The Clamshell Drill is the key to the golf swing, no seriously! If you want to see how the pros differ from the joes in just one simple drill, then this is it. If you struggle with losing your posture, swinging over the top, a sore back and inconsistent, weak shots, then you MUST learn this simple yet effective drill now! Here's a link to where Tiger was talking about some of these moves in his swing: Tiger Woods Talks About Hip Movement


All right guys, I am super excited to share what I'm going to do. Share with you today on one of the most, if not the most important moves in the entire golf swing. If you get this right, you're going to see how everything falls into place. And I've talked about it for many, many years, but I'm going to get into super detailed stuff today. That's going to help you understand how to make this move really simple by simply understanding exactly how to do a couple key pieces. Now, as you can tell, it's not exactly a golf weather here. So June 9th, we got three inches of snow overnight in the San Juan mountains, but it doesn't mean you could be out. You don't have to be outside practicing. You can do this inside. I'm going to use, as you guys know, I have a serious disdain for training aids.

So I just have a simple chair here. It's all you need a kitchen countertop. Anything that you can put about hip line is all you need to learn how to master what is the most important and powerful move in the golf swing. If you swing over the top, if you struggle with casting the club, if you struggle with your shoulders, getting to open an impact, if you struggle with losing your posture, especially these are all things that the tour pros don't do, but most amateurs do the exact opposite. I'm going to show you and explain exactly why today. You're losing your posture, losing your spine angle, not hitting the ball the way that you want and learn how to feel and get incredible power out of your lower body. By just doing one simple drill. And again, you don't need complicated gizmos and training aids.

I'm going to use a chair. That's all. You need to learn the secret of how the pros use the lower body. So here's what we're going to do. What I want you to do. First of all, I've been paying a lot of attention on the Facebook group to the videos you guys are posting on there and watching a lot of the same common mistakes over and over again. And people don't understand some of the most basic stuff or they, they kind of ignore. And we all kind of fall into these traps, especially as we get tired with posture at setup, I'm guilty of it too. And so one thing I just want to emphasize again, in this video is as you're setting up to this, I want you to set up properly, which means first lock out your knees. Like my, my quads are tight here.

I'm literally locked out, hindering from the hip socket, with my spine, nice and neutral, and then just barely relaxed them as you start doing this and just adding knee flex and getting Squatty, which we see all the time and online lessons into the Facebook group. It changes every single aspect of your swing. And it makes it very, basically impossible to do what you're going to learn, how to do today, which is, well, I call it kind of the clam shell, which you're going to understand. And just a moment, this clamshell drill, if you will, if you're setting up like this and squatter, you're always going to almost always have a little extra curvature in your lower back. Your upper back is going to be rounded like this, to get to the ball. I call it. You've heard me talk about the pumpy doll, puppy, dog, humping the fire hydrant.

This is kind of what it looks like. And this is maybe a little exaggerated for some of you and for others. You may look even worse. We've seen everything in between. So keep your legs nice and straight hindrance suck in this. Barely relaxed your knees. And you'll find if you're the type of person who struggles with the stance with being too wide. This is really common. When you squat down a lot, you take a lot of add a lot of knee flex. You're going to feel really stable. As soon as you straighten your legs, it's going to feel really awkward. And so you'll find that it's much easier to have a narrow stance. When you minimize that knee flex, you're going to have such better posture to dress and better angles to get to the ball. So anyway, now what I want you to do is get set up weight from the center of the ankle, to the middle of the foot or the back of the ball of the foot in the middle of the foot is kind of where we're aiming for here.

And this you're going to understand why in just a moment, because I see a lot of times, people will way back on their heels. You seen that a lot in the live lessons. And what I want you to do is be able to put your hand once you're in your proper setup, behind between your butt and the chair or countertop or whatever it else that you're using here. So a little bit of space here. Now, here's the key as you're going back, as you've heard me talk about so many times, it's so important to get loaded up properly in the back. Single. What does that mean? Exactly. And I've explained it in lots of different videos, which I'll kind of reference here as we go through this. But what I want you to think about as your hip going back and touching that chair. So you're erasing that space where your hand was in there and now you're lightly touching it.

This is your hip, going back, your knee, going back and your weight going back from the middle of your foot to your ankle. This is why it's important. You can't be way back on your heels. You have nowhere to go during the back swing. The golf swing is about movement. You have to be allowed to move. And so if you're already way back on your heels, where else can you go? You're going to already be off balance and you just don't have anywhere to move to. So it's really important that you all have your weight forward enough that you can move your hip back. Now, the first thing you're probably going to notice to say, well, Hey, I'm supposed to maintain knee flex in my back knee, right? Yes, absolutely. The opposite of that would be this. We don't want your leg hyperextending, but as you move your knee back, losing a little bit of knee flex is okay.

We just see this kind of stuff all the time. And also keep in mind the swing is happening in 3d. So as I move back, if you look at it here, it still looks like I have more Knee-Flex than when you're looking at it straight down the line, because my hips are turning as well. So anyway, back to this nice and tall through the lower body, my hands got the space. Now, as I go back, I move my hip back so that my glute touches the chair. This is important, super important, because so many times guys move out onto the balls of their feet, their hips slide, they don't move their hip back. You don't move into that hip. You need to move into this hip socket. And another video I did many, many years ago was talking about this crease that you can see in your pant, as you go back properly, you can see that my pant leg, you know, my pant, the front of my plants are nice and flat.

And I was like, go back and move into my hip. That's what creates that look of that crease in my pants. So that's what you're looking for. If you're looking at yourself face on you're moving back into this, loading back, getting weight loaded into that glute. Now that's the easy part to get, right? But so many people don't do it. So really using this, just knowing that you have a little bit of space and moving your hip back into it. So make a huge difference in what's going to happen next, which is the most important part of the entire golf swing. And that is the transition nine times out of 10. If you struggle with a proper transition, it's probably because you didn't load your lower body correctly and you overloaded your arms and shoulders. So when you're doing this, your focus is going to be here.

Your arms can. Now, first of all, they have room to swing back the lower bodies, helping move them back, and now they can stay a lot more relaxed. And now as you start down, your whole focus is switching sides. And what I mean by that is the left hip is now going to go back and go back further than what the left did or excuse me, what the right did. So now I'm just lightly touching it because my hips are also turning here. But now as the left goes back, my focus is sitting into that left side, pushing that left hip back, and even trying to bump the chair up a little bit, just a little bit here, just so that I get that hip back. Now you can see why I talk about this as like the clamshell. Cause as I'm standing here to dress nice and tall, my hip goes back.

That makes my spine angle increased slightly. And then as I get a little bit more aggressive with it, now you can see that my spine angle has gone forward even more. And my legs, this is what the squat to square is. My hips are going, my left hip is going back. My right hip goes back in the back swing left. Hip goes back in the downswing. And I look like I'm folding over like a lawn chair. That's the feeling or the look when you're looking at it on video, when you do it right now, the opposite of that, let me show you what's happened so often. So I'm going to stand up. I'm going to have a little bit of space here so you guys can see the gap and I'm going to over flex my knees a little bit. Now, as I go, go back, my hip doesn't touch this.

And in fact it may even move away from it. And then I fire with my right side, and this is my fault there. Now I'm nowhere near that. This is why people lose the tush line. They change their swing plane. They change their spine angle. Some of it has to do with starting with too much knee flex at address. And then once you do that, you can't move into this hip. And then you push hard from the right side and you move away from that. You want to do it correctly by moving the right hip back just a small amount. Then as you transition to the left, the left hip goes back. And now as you see it with the club, you're going to understand how these golfers on the tour, who do this really, really well look really powerful and have a ton of room for their arms to outstretch.

If I'm turning like this and losing my posture, my arms get stuck across my body. And I look really jammed up. It's costing me a ton of speed. It's hurting my back, but this is helping my spine stay in neutral versus kinking it and spinning it. My hip going back is creating room. And then I have all this room to release the club with a ton of speed and no effort, your lower body and the transition of the golf swing is everything. If you get this move right, this is how you do the squat to square. A lot of times when I'm seeing the squat to square, people are kind of going back and then just doing this. That's not what we're doing. The knee flex increasing is happening. As a result, as I'm sitting in the left side, this leg gets lighter and then there's, this leg goes back.

That's what moves this in forward from face-on. I'll do it just quickly so you can see the difference. Here's me too. Squatty all upper body. Now, as I stand nice and tall, right? Hip goes back, left hip. Now working to push that left hip back against the chair. Tons of room power is now at your disposal by feeling your glutes work in a golf swing. So all you need to learn a really powerful transition in the golf. Swing, a chair, a coffee counter, anything you have, you can put it in your hip up against, and you can learn how to swing, just like the best players in the world.

All right. So now let's take this drill and look at what a wide variety of tour pros to us. I've argued for years, the RST system, the method that you're learning, the techniques that you use, the fundamentals are what all of the tour pros use. The vast majority of tour pros all use RST fundamentals. Now of course, we talking about fundamentals versus variables. You're going to see things that may make the swing look different, but that's typically due to do with the arms and the hands and the club and the swing plane. Those are variables of the swing. Those are not fundamentals. I've explained why that is. And in another video, because simply those are dependent on how your body moves, how your other parts of your your arms move and so on. That's what creates a swing plane, et cetera. So let's look at, in this case, let's take Patrick Reed, Patrick Reed.

You may look at him and say, is he a rotary swing? Or is he using the RST fundamentals? Well, the stuff that you just learned in this video, absolutely. Let's take a look. So here you can imagine I've got that. The red line represents the, the chair drill that we just looked at. And so now watch, as he goes back, he obviously moves into it. Now watching the transition. This is where it really happens, where the load really happens and he really pushes back. Now you can see his hip is actually on the other side of that line, staying back against, and I watched the left hip boom on the other side, just like what you just learned, how to do in the drill. Notice the space that he has and the release with his arms. This is the RST movement. This is that clam shell drill.

This is the squat to square, all powerful golfers, all great ball strikers have the same characteristic. And it's all done by learning how to move from the core. Like you just learned in that clamshell drill. All right. What about DJ Dustin Johnson? You guys look at his swing. He's like, oh, that can't be an RST swing. He can't be using the rotary swing fundamentals because if you look at that crazy shot club face and super-strong grip and all that other stuff, well, again, those are variables of the swing. The fundamentals are, what matter? That's what moves the club is your body. So watch as Dustin demonstrates exactly what we just talked about, how his hip is already moved back. He's broken that chair. He's actually moved quite a bit. He makes a big hit turn. So he's well past that hip line. Now, as he goes back, look where that left tip is.

Again, all of the tour pros, the stuff that matters, the fundamentals of the swing, the stuff that we talk about in rotary swing the arm, plane, swing, plane, stuff like that. Those are variables. The body movement is what you have to focus on. And that's what the Dedra is all about. Teaching you how to do. And the tour pros all do it the same way. All right, now let's take another one. Brooks KEPCO, as he goes back, you can see on that hip line with the right hip during the peak of the back swing and the left hip goes back, stays there again, their hips move further back than where they started address. You can see clearly there's a space there. Now this camera move a little bit. So it makes it, he actually moves further back than it looks like, but you can still see the exact same things, all the tour pros do.

And when you compare this to the average amateur, nearly every single amateur in the, on the planet is moving their hips into the ball on the down swing. All right, let's take one. Last one. We all know who this is. Of course, Mr. Woods, same thing. In fact, tiger actually talked about this relatively recently, an interview talking about how he's trying to get deeper into his right hip. And then when his, when he was talking years ago, about how his glutes, when fires really talking about getting this left side to work in the downswing. But again, you see the same thing. He moves into that right hip into that chair that we just discussed in the drill even exceeds it. So now if you drew another line, you can see it's actually all the way out there. And then of course the left hip goes out there as well. And that is again, the main difference between amateur golf and pro golf is how the hips work and now you know exactly how to do it by doing my clam shell drill.

New to Rotary. Love this drill. My issue is on the transition move my upper body moves forward. Is it as simple as focusing on keeping the head relatively still that will help cure this move?
November 22, 2023

Craig (Certified RST Instructor)
Hello Edmund. Welcome to the site! The upper half/head will have to move slightly in transition. If the movement is excessive try to keep the head quiet, or feel like your back is staying to the target while the legs lead the way.

One of my bad habits is not opening my hips on the downswing. I suspect that in trying to correct this I have inadvertently introduced another mistake by initiating the transition with the lead hip and knee whilst leaving the trail hip and knee passive. This causes an increase in the separation between my knees in the downswing. Is this a mistake and do you have a video somewhere on the site addressing this issue? Thanks in advance, Gordon

Craig (Certified RST Instructor)
Hello Gordon. Take a look at the Sam Snead Squat Video. The movement you are describing isn't bad. My trail leg is pretty passive. I am also a very lead side dominant player. But, some players need to focus on trail foot pressure and leg movement to aid in clearing lead hip (for ex. Axiom).

gordon
Many thanks Craig, you are as quick as ever with your replies! I was a little put off by the comment in the Sam Snead video that it was for the advanced, i.e. well above my pay level! One thing I do want to try now is to more thoroughly implement the RST recommendation to roll the trail foot on the downswing until the club reaches 3 o‘clock. I hope this will help my weight transfer whilst preventing the knees from separating on the downswing. All this has been exacerbated by my needing a hernia op next week, - I want to protect the trail side muscles during (and after) recovery.
October 6, 2023
64x64
Craig (Certified RST Instructor)
Hello Gordon. Happy to help. The trail foot roll will aid in clearing the lead hip and ensuring you have transferred enough weight to the lead side. Also, if you think about the Axiom foot work from 6-9 on trail foot. The pressure is moving there to help ensure the weight moves correctly.

Hi Craig. I appreciate this video as it gets at a big problem I have which is moving into the ball on the downswing. Two of the main points of the video are more knee flexion and slightly more spine flexion in the squat move. This of course brings your chest closer to the ground. I can see how keeping the hips back creates more space for the arms however I don’t see why the loss of space relative to the ground wouldn’t result in fat shots? I know there was a similar comment/question on this before but the answer did not clarify for me at least. Thx
August 1, 2022
64x64
Craig (Certified RST Instructor)
Hello Michael. You shouldn't be dropping excessively, but lowering your seat and allowing for the increase in spine won't cause you to hit it fat. A couple factors to think about. Clearing the lead hip up and back will create more space for the release (You Hit the Golf Ball With Your Legs Video). Also, the fulcrum position of the swing is the lead shoulder socket. So the club head will be trailing in an iron shot but combined with weight shift you already moved the point another 2 inches ahead of the original setup position. That's why hanging back can be such a disaster. You haven't moved laterally enough to the lead side to change the bottoming out component. The pelvis shift roughly 6 to 8 inches in the swing. If you were in original setup position at the strike I could see where the conundrum would lie.

Thank you Craig for this very clear and detailed answer. As I look at the pro videos from Reed for example I may see why this is so difficult for me to achieve but I’d like to hear your thoughts. Watching Reed and others it looks as though the lumbar spine angle actually decreases on the downswing while the thoracic increases making the spine look very curved/hunched. This position would be impossible for my 70 year old spine to obtain. I find that my early extension issues seem to be related to wanting to decrease the lumbar like Reed to feel in a powerful position but due to the lack of flexion in the thoracic it makes my head/shoulders pop up a little. So should someone like me use this approach or should it be altered.? Thanks and sorry for the long note.

Craig (Certified RST Instructor)
Hello Michael. Unless there are severe mobility limitations. I've never really seen a reason someone can't maintain tush line. Yes, you will see more roundness in the thoracic spine. At the end of the day though tush line should be able to be achieved without a prior injury or major mobility issue.

with the left glute on the chair how do you prevent hitting the ball on the toe; pulling off the shot?
July 14, 2022

Hello Richard. Take a look at You Hit the Golf Ball with Your Legs Video. Lead hip back actually helps you increase spine angle. This, combined with square shoulders will allow for proper strike.

The clamshell looks like just what I need. Once the right glute is on the chair going back, would it be helpful to initiate the forward weight shift by thinking of letting the right glute slide a bit to the left in contact with the chair before the hips start to rotate?

I’m having a hard time on the takeaway losing posture and tush line moving towards my toes, as you can see from the pic there’s no depth in the right hand
June 9, 2021
64x64
Craig (Certified RST Instructor)
Hello Gavin. This is usually attributed to excessive knee flexion and improper hinge at setup. Combine with the shoulder plane getting flat the weight will move towards the toes. That's why you can see the loss of posture.

Just for clarification: when I really feel the left glute contract as the first "move" in the transition/downswing, i feel a strong rotation of the pelvis leading to an immediate post-up feel---versus when my first move is more downward pressure into the left foot, giving what feels more like the squat first followed by the post up. I assume this is more what I should be feeling, but any comments about what the first move/feel should be to begin the weight shift/transition would be appreciated. Thanks--really feeling the improvemnet in my swing!

Hi Craig Now the posture is better, you said that I was hitting it with the hands too much. My thought is to get over to the left and post up should I’ve doing something differently?

Hello Gavin. Those are correct thoughts. But, from setup and swing you had to do a lot with the hands. We hope to diminish that now that we a getting you into a better position for a cleaner release.

Apologies if my previous post was incomplete, I will resubmit. I have just rewatched the dead drill video. I have currently completed nearly 2000 backswing reps and I have a few questions: 1 Do you recommend 3000 reps of every step of the Dead drill ( for a total of 18, 000 reps)? 2 Does it make sense to treat the first three steps of the Dead drill as a single entity (provided that all of the checkpoints are executed properly), to get the feel of combining them as an organic whole? 3 Is the Clamshell drill a good adjunct to the first 3 steps? It seems to me that it would be very valuable in maintaining good rear hip position and proper weight distribution throughout the transition Thanks David Ryan
March 25, 2021
64x64
Craig (Certified RST Instructor)
Hello David. No it is not recommended to do 3000 of each step. Start with chunking DEAD 1-3 with the goal of blending and doing them at pace. Clamshell can easily be incorporated to the 3 pieces. In fact it is recommended for tush pushers.

Working thru many reps of dead drill with club. 3 steps, takeaway, squat to square, release - done in sequence but with short pause after each to check. After 1000 or so reps what is the recommended way or rep schedule/speed to start blending these into 1 move?

Hello Andrew. Tour Pro Downswing Sequence Drill would be a good follow up.

The surprising thing in that video (at least to me) is that I interpret that the "effort" in the downswing is very early, and sequenced very tightly. Lateral done by lead arm 10 oclock, torque(squat) by lead arm 9 oclock, and post max veritcal force by lead arm 7 or 8 ish. To me, on the few tries I did blending that together, that feels like the swing is "over" before the club gets to the ball - and that I'm just hanging on while the club head freewheels thru impact and eventually tugs the arms in the follow thru.

Hi Craig, Just got a swing review yesterday and my teacher suggested the clam shell video. I think the longer the club, i.e. driver, the more I want to pull up and out of it to make room for the club shaft. Should I practice this drill body first then maybe one-handed driver swings? Thanks!
March 3, 2021
64x64
Craig (Certified RST Instructor)
Hello Kyle. For sure do it body only first. The movement shouldn't make much difference when using different clubs. But, if you tend to make the error more with the driver. I don't have a problem. But, 1 handed driver swings people tend to yank the club so you have to be mindful. I would work up to the driver. Master with a smaller iron first.

Thanks Craig, I think a lot of it is that the club toward the top of my swing carries me further and I get out of sequence. Would that just mean more body drills, then introduce arms then club after?

Hello Bob. You can start with slow motion drills to get the movement down, but then start adding a little pace. As you clear the lead hip behind you during the posting phase you don't want to dive the chest, but you will feel the chest covering the ball during this phase. Take a look at You Hit the Golf Ball with Your Legs Video. Chuck will describe the same senstation.

Hi Craig Still having issues getting the right leg to straighten on the backswing, is there something specific I can do, does it mean I'm not getting the weight across enough? Also on the downswing once you post up should that be an automatic release to square the face, I'm hitting it a lot out of the heel with low cuts. Cheers,

I’ve been drilling bases on the 5 Minute series - setup, takeaway, backswing, etc. is the concept of keeping contact with a chair or a wall a good substitute for the squat to square aspect of the downswing? It seems that the clam shell drill will have the added benefit of keeping the proper posture throughout the whole swing.

Hello Eric. This will work well for retaining posture and chair/wall will help you achieve the sq to sq aspect.

I know it has been recommended to use the Sam Snead power squat video to help with tush line as well. Could you use those video cues, which was trail side knee externally rotating in coordination with this clamshell video? I see Chuck's trail side knee coming closer to his lead side knee in this video in comparison to the Sam Snead video where his trail knees is externally rotating. Any thoughts?

Hi Chuck : Just reviewed my swing analysis and it was awesome. Coincidentally, last week I had been playing poorly, and I remembered from a previous lesson that I moved my head off the ball, so I concentrated on staying centered. Shot a 44 on the front nine, then the lightbulb came on, focused on staying centered, and shot par (36) on back nine, hitting every fairway and green! Handicap has risen from a 8 to 11.5 over the past year , still not bad for a 70 yr old. So, when you did my swing analysis, and saw my huge head move off the ball, it was like, yea I know that!! Here is my question and it pertains to the second issue I need to work on, the clam shell drill. How do you increase your right knee flex as you start the squat to square - and move to the left side- without pushing off the right foot? I guess I have been hanging back on my right side too long, by just laterally moving to my left leg, and keeping my right foot on the ground longer which I know you should do . It just seems counterintuitive to squat to square, increase your right knee flex, and not feel like you do this without pushing off your right foot which is cardinal sin in RST. Thanks again, and I look forward to working on this transition drill without the above mentioned confusion. Greg

Craig (Certified RST Instructor)
Hello Gregory. Think about the squat. What is squatting? Increasing knee flexion to be able to leverage the ground and use the leg muscles. To allow for the increase while still opening up the hips I've had lots of success combining the Sam Snead Squat Video (counter torque move). This allows for you to feel the trail knee movement, but without the want/need to push early as the hips start to open.

Left arm parrallel snip from the top - chuck talks about just focusing on getting the left hip back before the right leaves the chair. If I make my weight shift and keep my chest closed it feels like a close hip slide and it’s solid but goes left. Blending that sit and rotate is tough!

I worked on this more yesterday and think I have a learning / feel that works. I made practice swings / drills with my left foot staggered back and had that “feeling” that my belt buckle never gets closer to the ball and I’m working away from the ball...basically the centrifugal forces Chuck mentions in the “hit the ball with your legs video”. My lower body feels much more grounded and more of a pull down move with my arms

Hi Craig, In transition and post up I don’t feel my left butt go further back than my right. If anything less. I don’t know why I can’t replicate what you do. PS: just watched Rahm win. He and Folau have such short, compact backswings. Should we aim for that? How does one do that with power?
September 1, 2020
64x64
Craig (Certified RST Instructor)
Hello Jim. You want big body turn and minimal arm swing. There are multiple power sources in the swing. Those players use a lot of leverage from their wrists. 2/3 of your speed will come from lag alone. If you can't get your butt back. Make sure when squatting your weight isn't already too far back on the heels. You will have no where to go when posting.

If you're not very flexible in the hip or lower back, would this be harder to do? If so, are there stretches that you would recommend? I know I am not very flexible. I'm a low handicapper and I find this, keeping my tush line, to be hard to do, but I am working hard at it. Thank you!

New to Rotary Swing, so please bare with me... Does the push vs pull idea apply here as well? I know we want to “pull” our weight shift and turn in the back swing by “pulling” from the right shoulder blade and right hip, but should we also be “pulling” from the left shoulder blade and left Hip to start the transition and complete the downswing? Or is it a feeling of “pushing” from right side to left side for the transition and downswing. I hope that made sense. Thanks in advance for the help.

Hi Jake, welcome to the RST family. The push vs. pulling concept applies in every part of the swing. In the downswing the focus is pulling the hip and left oblique instead of the left shoulders. Shoulders should feel passive.

Two things: is it ok to feel that the right glute just move straight back to maintain the ancle as the balance point as you turn or is that risking improper rotation? Also, ive Always found "sitting in to" a confusing term. Is it referring to the use of the left glute to start pulling the left hip back or something different/more?
August 15, 2020
64x64
Craig (Certified RST Instructor)
Hello Jens. If you just move it straight back you might not shift weight. Just make sure you are loading into the trail glute with some weight shift. The lead adductor will start to pull the weight back as the torso will help square the hips planting into the lead glute/leg. Most players can think about pushing their trail foot into the ground and then their lead foot into the ground to start facilitating the correct motion.

Gerard
Is it fair to say that in the transition, the angle between the spine and the femur decreases, and not the knee flex as I’ve been doing? This seems contrary to comments I’ve heard that the “squat to square” is like going into a squat, bc in that instance, it would be knee flex that changed?
August 13, 2020
64x64
Craig (Certified RST Instructor)
Hello Gerard. The knee flexion will increase during the squat. You don't want to manually be decreasing the spine angle. The drop in the head is due to the squat/added flexion and as you clear the hips the backwards motion will allow you to maintain posture. Take a look at You Hit the Golf Ball with Your Legs Video.

Regarding my backswing Craig, further to your comments in my review, I looked again at some of Chuck's videos including this one above and noted that his lead knee tends to bend towards his toe of his right foot; whereas mine goes more towards the ball. When I tried this movement in my backswing, allied to letting the lead foot roll to the inside edge definitely makes my backswing better as I feel the obliques stretching and right butt controlling the action. I don't get that big gap opening up between the legs when my club is parallel to the ground. I also found by feeling my right butt starting to go into a bit of a sitting position, this tends to slightly lower my head at the top of the backswing, hope I have this idea correct. Will try and get some video of this later.
August 12, 2020
64x64
Craig (Certified RST Instructor)
Hello James. Players have the tendency to have the lead knee work too far straight out over the lead toe. As you rotate the lead knee working a little more towards the trail side, but over the toes is fine to help facilitate the weight/rotation.

really like this drill in helping get the right feel for how much hip movement i need to do. Feels like a lot less action than i was trying for and you keep much more square than i thought. One question... on the backswing i get that the right glute brushes the chair. on the downswing the right glute obviously moves away from the chair but i'm not yet getting the feel for how far is too much. any tips on how much it can move away before being more of a right hip push shot
July 30, 2020
64x64
Craig (Certified RST Instructor)
Hello Richard. It shouldn't move much away, but has to during post up. If the trail foot is behaving, left butt cheek on the chair and posture has been maintained. You should be good. You will tend to see the usual early extension elements of push and weight towards the toes if over active.

Hi - been struggling with "getting stuck" lately - have found that using this drill seems to fix it. When I squat and move chest lower to the ground (clam shell) it feels like the club/arms are being "pulled down" in front of my chest and then the rotation (via the hips and lats) "pulls the club out" - is that the correct feeling? Thanks
July 29, 2020
64x64
Craig (Certified RST Instructor)
Hello Alan. The chest won't dive a lot when squatting. Make sure it's solely the legs lowering your height. But, the post up move is correct in diagnosis. Clearing the hips to have room to deliver the club.

Further to upping my review yesterday I felt that something was not quite right. I watched the "How Ernie, Rory & Tiger Move Their Hips for Effortless Power - Golf Lesson" Live lesson and realised what the issue was. It was not shifting my pelvis (middle back belt hoop) towards target as I changed direction forward. Also, where Chuck refers to as you pull the left (lead) hip back the left shoulder is pulled up and back at the same time. So went back out in my net and worked on that and it felt much better and my arms extended towards target because my left hip had cleared out of the way. Sorry Craig for not getting this done when doing the review; was more focused on that head issue and knee bend at setup, plus really trying to post up that left leg by rotating and turning back away from target at impact.

Further to your comments on my review Craig. After upping my review I was aware about those issues of not shifting my weight quick enough left after watching Chuck's live lesson with that big guy. I accept everything you said in the review but what you never called out was the fact that when my arms got level in the backswing, as was rotating my hips back, I was failing to move the right butt towards target triggering my forward swing. What I did appreciate was your advice in the setup of when standing up straight, soldier like, keeping my body totally perpendicular, then bending from the hip joint until and at the same time letting my butt stick out until I could see the ball without arching my head forward to do so. To assist in this, I placed the shaft of my 8 iron down my back with the grip end firmly against the bottom of my spine and the club head resting on the top of my head and the top of the shaft keeping my neck at the same angle as my spine. This worked a treat, and when I could see the ball without any flexing my neck down to do so, I could feel the weight on my toes go lighter as mentioned by Chris in "Common Golf Setup Faults and Fixes". Will practice frequently indoors so that this becomes second nature. Thanks again to all your welcome comments.
July 29, 2020

James
Regarding my setup height, after comparing angles against Chucks setup I think I need to bend over a tad more of my upper body towards the ball, not forgetting of course to extend the butt as I do it. My comment about this was triggered by the fact that the end of gingers on the grip do not reach the perpendicular plumbing from my chin as Chuck's does. I know you mentioned this before to me BG, it is just something I overlooked when checking my setup angles viewing on LiveView DL; really must use this more as it does highlight areas I need to focus on. See picture below, most of the angles do coincide with Chuck's apart from the back tilt towards the ball.
July 29, 2020
64x64
James
On checking my setup in a mirror, when I tilted over a tad more from my hips and bumped out my butt a tad to combat the balance it looked a lot better. This then put me more in sync with Chuck's angles regarding the angle from under his armpit to the butt end of the shaft (75.96) against my (80.85). Plus the shaft angle relative to the ground, 50.08 Chuck, with me 54.29. I realise I may be a bit more upright due to my height taller than Chuck. Anyway here is another capture.

Kevin
Just a clarification based on my recent swing reviews and the online lesson yesterday 1) head movement / balance - I had a balance issue of moving into the ball on the backswing - just confirming the head can go up and down but not in toward the ball? 2) in my review today I lose the tush line when the right cheek comes off but regain it on the post. To get both checks to touch the chair it seems like the shoulders staying shut and down helps keep the right check back while you start the left hip rotating and posting then allowing the right cheek to come off the chair - does that sequencing make sense?
July 28, 2020
64x64
Craig (Certified RST Instructor)
Hello Kevin. In the backswing, you don't want a lot of head movement. It can move a slight bit away, but you shouldn't be seeing a lot of up and down motion. Less spin from the shoulders will help. For you it is a little trail side push. That is why the head hangs back during the shift to the lead side and you get a little tilty.
July 29, 2020
64x64
Kevin
I’ve been working hard on getting left earlier and sitting left but still can’t seem to maintain the tush line. Not sure if it’s my setup - knee flex doesn’t look too bad but maybe more hip bend and less knee flex? I maintain the tush line to the top but that first move from the top is where I’m stuck - missing it left with a hook

After watching Chuck with the latest live lesson on this drill, I understand a lot more of it now.

Hey guys, really enjoying the process so far. I never thought of locking the knees, then hinging from hips, then flexing the knees to address the ball. I usually hinge from the hips with the knees slightly flexed. I don't feel or look like I'm too squatty. Would you suggest a change in set up process with the "locked knee first" approach for every shot? Thanks
July 28, 2020
64x64
Craig (Certified RST Instructor)
Hello Christopher. The main goal is to make sure you hinge from the hips sockets and have the weight balanced. After practicing the setup multiple times you may not need to return to the locked knee position for every shot. Just a good method at making sure you complete the hinge/balance correctly.

Mark
In order to get the timing of this drill in proper synch, it appears to help me if I transfer my weight from my right heel to my left heel from the ground up (to initiate the squat to square) and post up immediately after I rotate my left hip to neutral joint alignment with my left shoulder (that is pulled by the hip turn) and my left heel. When I focus on moving from my left heel to right heel from the ground, my shift appears to be smoother and a bit faster. Is this an appropriate swing thought. Also, is the clam shell drill movement appropriate for at least long wedge shots.
July 27, 2020
64x64
Craig (Certified RST Instructor)
Hello Mark. For all stock shots this will be appropriate. Even full wedges. The weight will move a little more in the figure 8 pattern with the feet. If you just stay on the back of the heels you may find it hard to post up.

Hi Terry. It's the same move as he did earlier in the video just with a club. When you use the lower body like the clamshell drill the club moves down automatic, the only thing there is left is the release, which is basicly letting go. Look at the 5 minutes to the perfect release to understand that one. Hope that helps.

Hi, should I still press the right foot into the ground at the top of the backswing, or is that just to start the backswing and to halfway back? It helps me keep my right knee bend.

I think I have it now, I just press into the right foot in the takeaway until left arm parallel and then if I just keep turning the right shoulder blade and keep my right arm as straight as I can I'm in a good position. The same feeling as if I do the step drill and stop before I come down. It feels more 50-50 or close anyway while still feeling the upper body behind the ball.

On the transition to the left side this video seems to imply that the right hip is the silent partner to the left on the squat to square move. Chuck's latest live lesson emphasizes the role of the right hip in getting to the left side perhaps marginalizing the role of the squat to square. Am I misinterpreting and would appreciate some clarification because I have fallen into the arms for power mistake.
July 3, 2020

Craig (Certified RST Instructor)
Hello Neil. You don't need to push with the trail hip to get to the lead side. You want to load the trail glute early because of the kinematic sequence in the golf swing. Loading early helps you start to shift to the lead side first in the transition. Take a look at Which Muscles to Feel in Golf Swing Transition Video to see how you pull to the lead side.

I have been on Rotary Swing for a few years. This video is great. Whenever I play I hit 3 to 5 of the most amazing golf shots. Straight, great flight, powerful. I wonder if it is the swings I have properly loaded into my right hip and glute. Playing around with this at home. It seems like it is almost impossible to get into this position if my weight is on the balls of my feel or heels at setup. Question: it seems that if I setup on my ankles this good hip movement is almost automatic (assuming proper posture)?

Hello Eric. It won't be automatic. But, you need to be over the ankle joints to have the ability to make the proper shifting/foot work.

I am having a hard time understanding where exactly my weight should be and where my right knee (right handed golfer) should be in this drill. When I push back and engage my glut, it seems to have my knee almost hyper extend and the weight go to the outside of my foot. I am not even making it into the squat yet because I am trying to teach my body how to just turn at the hips and not use my arms. Any advice would be great.

Craig (Certified RST Instructor)
Hello Brad. Sounds like you are over exaggerating the distance of the chair behind you and how much to move the hip back. You should feel like the weight is center of the ankle joint trending towards the heel. Some images here, or a swing review would be helpful to clean the move up.

Hi Craig. Previously Chuck has mentioned that foot pressure moves in a figure 8. Watching the feet in this video Chuck seems to move his weight directly from the left heel to the right heel . Is this the correct feeling to have?

Hello Ian. The weight will move more similar to a figure 8 in the feet. It may appear that way in the video, but a word of caution not to get too far back on the heels. Balance in life and swing young apprentice.

This video is the biggest help yet. Maybe it’s just what I needed when I needed it but either way just like Chuck says in the beginning of the vid. Getting you setup posture correct and moving the hips properly is HUGE. I think of it as the DEAD drill simplified. Thanks for all the the great content but especially this one.

Just had to write to tell you about the success I'm having since concentrating on this drill. I've been blown up a couple of times, had at least 20 concussions, had multiple surgeries/procedures on neck, back, jaw, shoulders and hip ("It's not the years, honey, it's the mileage.") and now have onsetting arthritis, so I don't turn that well or get my hands up very high anymore, certainly not like even 10, 15 years ago. But this move, where I am focusing on shifting my weight/pressure and then turning around the center of my hips, not only restores distance, it lets me swing relatively pain-free. I got a late start to the season due to recuperation time, and yesterday was the first time this year I was able to make full swings with longer clubs. I have been doing this drill inside since the video came out, going very slowly, making sure I could do it and make center face contact. This made a tremendous amount of difference/improvement to my whole swing. My pressure is more on my lead leg now, and for some reason I'm getting more lag which is resulting in PURE shots (center face baby draws) and good distance. I'll keep working. You keep offering great instruction like this, please!

One more thing. It's very clear to me now why Chuck says, "You swing with your legs." In martial arts training, we say, "Control the hips, and you control the fight." Just as true in the golf swing. Everything else follows what you do with the hips and legs: core, shoulders, arms, hands, club. Your ability to make solid, center-face contact is made so much easier.

Hi Guys- when I practice this drill, I end up much farther back on my left heel than before at completion....I'm guessing this is because losing the toosh line is ingrained now, but I wanted to confirm this is correct when weight is on the front foot. Where should I feel the weight when on front foot?

Hello Todd. It will be moving to the heel. But, I don't want you falling off the back of the heel. Still firmly planted with a little bit of option to wiggle the toes.

I see on the PGA Tour a number of players lowering their torso in the downswing, Tiger being an extreme example of that group. I tend to hit some shots thin and when I think “Clamshell” there is definite improvement (along with right shoulder back). Is this a good concept to work on?
June 17, 2020

Hello William. The clamshell is a great concept to work on. However, the thin, or fat shot can be due to multiple different variables.

This video really helped me and my balance as I was moving out toward my toes on the backswing. Hit it solid tonight for the most part but hit some hard hooks low left off the toe with driver and fairway woods a few times. I was trying to feel like I kept the right shoulder back along with the clamshell drill and maybe my hands are really whipping through impact faster now? Maybe a right side push and not pulling the hands down?

Great drill, Chuck. I do notice sometimes when doing it my club bottoms out before impact hitting the ground behind the ball as a result of the increased spine angle. Any idea why that is happening?
June 16, 2020
64x64
Craig (Certified RST Instructor)
Hello Adam. Your spine angle shouldn't be dropping so much it causes a fat shot. The lead hip is clearing out of the way and lead shoulder will still be above trail at impact. Sounds like you are driving the upper half into the ground.

Hey Chuck, Amazing video, and by far the most simplified way I've ever seen the lower body move explained. This drill essentially combines the backswing, transition and post up into one move! Somehow the DEAD drill just got even more simple.

Hi Chuck, Patrick Reed's trail foot hardly moves to impact position, the others tend towards being on their toes. How significant is that in relation to executing the correct movement for hip rotation? Regards, Arthur.
June 15, 2020
64x64
Craig (Certified RST Instructor)
Hello Arthur. Ideally, you don't want to lift the trail heel before impact. Take a look at Role of the Right Foot Video. Too little foot won't allow you to finish weight/hip rotation and too much will allow excessive hip rotation/loss of tush line.

How much should we flare the left foot in order to maintain the left cheek tush line post-impact? Practicing the clam-shell drill, it's much easier (as a 40 year old golfer) to initiate a backwards thrusting left cheek and maintain balance into a a full follow-thru if I flare my left foot ~45 degrees instead of my normal ~15 degrees.
June 12, 2020

Craig (Certified RST Instructor)
Hello David. I don't mind if you have a splay in your feet at setup. However, 45 degrees would be a little excessive. Take a look at Should You Splay Your Feet at Setup Video.

Would I be right in saying that the weight on the backswing would be moved into the heel (from the address position of being centered over the ankle) and then on post up would also be back in the heel as well (from centered over the ankle at address)?

Chuck I put myself on video and I stand up on the downswing slightly. I can make myself keep the tush line, but I loose mph. My driver is about 103 standing up and about 98 keeping the tush line. Will that change after doing this for a while?
June 12, 2020
64x64
Chuck
Any time you do something new, you're having to think through how to do it a conscious level and the brain simply can't process things fast enough at the level to move fast, so in many cases, you can lose speed during the initial learning phase. However, the fact that you're at 103 lets me know there are many other areas that are costing you speed, so it's not just learning how to move your hips differently, there are other things going on that need to be addressed as well.

Hi, This is so oportune, a light bulb moment and confirmation of something I've stumbles onto. Like so many I've strugled with a number of faults, excessive arm lift in the back swing, improper transition and loss of posture in the downswing - thus coming up out of the shot. I have been working steadily with the "Squat to Square" move - having sorted my excessive arm lift. I must admit I had problems getting my body to understand how to move from the the right and back to the left. In the last two weeks I discovered that towards the end of the back swing if I pulled my left obliques and abdominals back it did a number of cool things like, it automatically started the weight transfer from right back to let, if it was timed correctly it added wrist cock, it got my left buttock moving backwards and cleared loads of room for my arms to drop so that when my hands reach my right thigh the club is parallel to the ground. Now all I have to do is add a proper release and figure out what my arms and hand should be doing from that parallel to the ground position through impact. Great great video - I'm sure it will really clarify things for a great number of befuddled golfers. Keep up the good work.

Randy The swing issue I continue to struggle with is that I tend to dip my head and left shoulder down on the takeaway and then have to raise up on the downswing to bring my shoulders back to square with the consistent result that I hit the ball thin with irons and fairway woods, often just topping the ball. Any thoughts/drills to work on here? many thanks; your series is terrific.

I have had issues with hip spinning and with this drill I am afraid I could be spinning the hips up and out to fast. How fast should you clear your hips up and out as suggested in the drill to maintain the tush line?
June 11, 2020

John
Somewhere Chuck talks about keeping the right (trail) foot on the ground while posting up, which keeps the hips from spinning out during that move... While still getting the weight well over to lead side.
June 12, 2020
64x64
Craig (Certified RST Instructor)
Hello Ryan. Had issues? . You don't want to drop the hammer too much. Particular to you and your swing. You need a transition. Most of your move is racing to get to the post up. Should feel less aggressive when drilling for you.
June 11, 2020

Martin
Hi, as suggested I have tried this out and really like it. I have one question and one suggestion. The question concerns weight shift. Say transition ends with weight 50/50 - 40/60 (trail/lead) and then you post up. From the video I understand that the hip at this point should have turned to the postion illustrated and from there post up? So end of transition you have moved weight so it is centered or slightly favouring lead with hip rotated slightly further than on backswing. Then transfer all weight and straighten lead for post up. My suggestion> I didn't have a chair so stacked an impact bag on top of a stool. Just by chance this was the exact height of my leg so at the point where the hamstring stops and glute starts once at address. So for the backswing I felt the top of my hamstring push the bag. The key point was that for transition I could just then lightly feel as if the very end of my glute was actually sitting on top of the bag and then my lead glute would move it back. This made the move easier, especially the sit, it just felt like very gently sitting not as if I was trying to do a golf move at all.
June 11, 2020
64x64
Craig (Certified RST Instructor)
Hello Martin. Thanks for the suggestion Martin. Yes, once the hips are square weight (40/60) you will finish the weight shift during the post up phase.

Sorry, just one other comment. It's related to this and my swing review re losing axis tilt. I think one mistake I have been making is to do the body only drills without looking at an actual ball in the correct position. I've added one and this has helped me focus more on where my head is in relation to it.
June 11, 2020
64x64
Craig (Certified RST Instructor)
Hello Martin. Absolutely. We suggest often to have something on the ground to give you a focal point of where the actual ball would be. Helps with excessive movement out ahead of it when drilling.

My head drops significantly from setup to post up in doing this clamshell business. Is this a problem?
June 10, 2020
64x64
Craig (Certified RST Instructor)
Hello James. You don't want your head bobbing up and down excessively during the swing. In the backswing, shouldn't see much variation in the head. You will see some drop in the transition and it should maintain into post. Make sure you aren't over exaggerating the drill how far the chair is behind you, or pushing the lead shoulder causing some head dip down.
June 10, 2020

Chuck - When you demonstrate how we should look without a club down the line with our left hip moved fully back it appears your shoulders are almost 45% open. Is this an optical illusion? Your shoulders do not look as open when you add the club and demonstrate the same move. I think this video is going to be a mainstay video for RST. Thanks.
June 10, 2020

I was not demonstrating the correct shoulder position while doing this, just focusing on the hips. The shoulders would still be square at impact as per the other drills.

Of course, I thoroughly understand now. I worked on this move a lot today and for the first time ever I can feel a powerful transition and post-up that results in surprising club head speed. I really appreciate the level of detail you gave us about how the hips move into the transition and then into the post. Having the stool as a reference point was brilliant. I played a few holes at the end of the day and had wonderful results. I am going to video my improved move and send it to CM for his blessing. Thanks for re-visiting this crucial part of the swing.
