Chuck, What are the recommended flexion/extension ranges for the Hackmotion? I'm not sure the pattern a is a good match for the Goat swing. Thanks!

Chuck, I ordered the HackMotion Core (thanks for recommending this and getting us a discount!) and I am > 95% accurate at the top of my backswing but am averaging around 15 degrees of EXTENSION at impact. Per the graph of a flip presented in HackMotion, it does not appear that I am aggressively flipping but I am not sure. Do you have any suggestions on how to get more flexion at impact? Do I need to upgrade my HackMotion software to the Plus or Pro? Thanks again for all of your great work on this website! Chris.

Hi Christopher and thanks! I'm working on a video right now that covers ulnar/radial deviation as they go hand and hand with extension/flexion. But if you don't want to go for the upgrade to the Pro version to get that data, realize that the most common cause of the flip when looking at the data is trying to bow the wrist too much too early and then you run out of anywhere to go as I discuss in the video or you are cocking the wrist too much (too much radial deviation on the Hackmotion) and this cups the wrist (too much extension) and makes it hard to get rid of the extension in time before impact.

Chuck, the HackMotion videos are fascinating and a wonderful insight into understanding wrist angles during the swing. This might not be the best place for my question, though it is related. I joined RotarySwing to learn a swing that requires less swing thoughts and I am delighted with my progress so far. Tell me, why don't you address the ball with the strike wrist flexion then maintain that angle throughout the whole swing? That would reduce swing thoughts, I think.

The golf swing is too dynamic. As much as it logically makes sense to take this approach, there's a reason you almost never see a good player doing it. You must give the body areas to move THROUGH the swing. Just trying to hold it static doesn't work as it restricts movement too much and in this case, actually most often leads to the exact opposite desired result - a flip.

Chuck, I have to admit that my head is spinning. The GOAT Code and GOAT Theory videos have been eye-opening and exciting. My swing feels more free and athletic than ever. I have swing feels instead of swing thoughts and it’s been fun to be a part of your deep dive into what the GOATS really did in your swing. But I find myself on the range not knowing what feel should I work on. The side arm throw with a weight shift? The wide-glide-wide drill emulating Tiger circa 2000? Or trying to get into the GDP and working on getting my wrists to copy Thorbjorn Olesen? Or do I have to do all of these things to swing it my best? Is there a hierarchy to all of this? Is there a framework in which to categorize all of this new GOAT info? I’m still topping out at 105mph with my driver so I think I have to be missing some pieces.

Focus on the main core videos until you have the basic motion down, then simply use GDP as a checkpoint and the refining videos to dial things in. If you can hit the ball well with wide glide wide then you are well on your way.

Thanks for the reply Chuck. Swing is feeling good as I quiet the body and “throw from the top”. Contact has been great and I’m picking up speed for sure. Club Path has zeroed nicely, but club face can be a little open, a little shut or square. So misses are right and left. I’m trying to bow the left wrist as I throw from the top while moving the hands fast. Any tips on how to keep the face more stable in the downswing and through impact?

You may be getting too much deviation (wrist cock) which opens the face and then you are struggling to square it back up. Could also be too much rotation, but I would start with deviation.

Thanks Chuck. Radial deviation correct?

Hey Chuck , Are you still thinking the club is ‘thrown’ from the top with this new wrist data ?
March 10, 2024

Chuck (Certified RST Instructor)
Yes, you can see that in the data in Olesen's swing. I've had this asked a few times so I will probably do a video on it soon

Chuck, it's great to see these videos with HackMotion. I've been using HackMotion for about a year, working with Craig on changing my swing. I agree with you, absolutely the best training aid I have ever used. One questions regarding when to bow. When I'm doing a Lead Arm Parallel drill, the time from the top of my backswing to GDP is 0.23 seconds and the time from GDP to impact is 0.07 seconds and this is with a shot that only goes 100 yards or so. When do you "think" about starting to bow? Is there a trigger point in your swing when you do it or is it, as you say in the video, only by drilling more slowly? Thanks, Neil. BTW, whatever you pay Craig, it isn't enough, he is fantastic!

Hi Neil, great question. As you can imagine, it's impossible to "think" the timing of this as it happens much too fast. But, if you move into GDP, the wrist will naturally start to bow. When it starts to flip is when we aren't moving through GDP correctly. The momentum and weight of the clubhead when the trail arm is in GDP leaves little choice but for it to bow naturally.

Thanks Chuck, this is exactly what I needed to see! Got my Hackmotion sensor (thanks for discount!) on Monday and was practicing with it. My initial thought was that I needed to bow my wrist at the top of the backswing, and exactly like you say, it was showing me flipping at impact. Now I know better. BTW, for rest of members you can start with the base Core model at $280 and then choose later to upgrade to Plus or Pro, which is a software update you pay for. The hardware is exactly the same for all 3 versions. Thanks again!

Chuck, thank you for the simple explanation of a very difficult process. I can't wait to calm the wrists and hands and post some great results. This is absolutely AWESOME content! This is simply another Homerun in the GOAT series! Keep it coming! This information is finally giving us the simplification of what needs to be done to be a great ball striker. AMAZING STUFF! Keep pouring it on. Thanks again. You're Da Man or should I say Da Decoder of the Golf Swing! Unbelievable!
