How Club Face Contact Affects Compression

This video studies compression in terms of where you hit the ball on the face of the club. Find out how you can change club face contact to reduce bad shots. You'll also learn about moment of inertia (MOI) to see how the stability of your club at impact determines how solidly you'll hit the ball.

  1. Center face contact gives maximum compression. 
  2. Shots off toe or heel cause face to twist and decrease compression.

Where should the club face be relative to the ball at set up?

Craig (Certified RST Instructor)
Hello Alden. Parallel to the target line and in the center of the face. The toe will be slightly off the ground if the club is fitted properly to you and setup is correct.

Thanks Craig. Asked because I Heard some advice about Hovering over the ball and club never touching the ground. Trying to ding a good club fitter any advice about determining who actually knows what they are doing?

Hello Alden. Gotcha. Some of that is personal preference. Jack N used to hover the club and others place it on the ground. I think allowing the club to settle on the ground behind the ball helps relieve a little tension and doesn't allow the little extensor muscles in the arms to fire the club back too soon.

I don't know where to ask this, but can you comment on how RST will affect stiffness on iron shafts? I seem to remember something about the RST swing being a lot less violent, and therefor a softer flex might be desirable. I know on drivers all out speed designates stiffness, but on irons we're looking for compression and control.

Hello Dan. There are a lot of factors when trying to get properly fit. However, RST is geared more towards efficiency and effortless power. You don't need something overly stiff because you then would have to work harder to get the proper dynamics out of the shaft.

Here’s where I’m confused - in video 1 (and in many others), what I feel Chuck is saying is the arms and hands are very passive. When I do the drill in video 1, the club feels almost floppy to me, but I see and understand how it gets you speed. The lead leg posting up, hips rotating, and core engaging all release the club. Awesome. The confusion comes in when I see him demonstrate the 5 min to the perfect release drill. To my eyes, I see very little of those movements happening. Instead I see what I feel like he says NOT to do, which is pulling of the arms across the body and very deliberately controlling the face of the club. So, how do I reconcile this and how, if ever, do I stop having this sort of floppy feeling? Or is that feeling actually the lag and “effortlessness” that I should be / have been searching for? Thanks for any help.

Hello Randy. You have to train the release and proper rotation of the lead wrist. At first, it will be very manual and deliberate. You need to ingrain the new motion. Once the release is trained and you understand how the control hand squares the face. The posting up is used as a trigger to start the release. It should become more reactionary versus a forced movement. Think about a hammer. If you methodically moved the hammer to the nail, but once you ingrained the movement and performed it faster. You would just allow the release of the hammer to strike the nail.

Will this work with a driver?

Hello Kevin. You may with a driver. It can be challenging doing the small shots lead arm only though. Also, the driver's sweet spot isn't necessarily right in the middle.

Another great video...thank you! I have a long way to go to be able to take a full swing with one hand and not hit the tees on either side but understand a bit better a simple/efficient way to help build such fine control into the swing to enable me to square the face & improve smash factor. I suggest also using clubface tape as a way to get some relatively clear, quick & cheap feedback.

HI, a couple of teaching pros looked at my swing on video and both agreed that I get too much rotation with my irons going into impact. The club face is in a pretty solid, square position at the top. As a result my most pure struck irons always hook. This does not happen with my hybrids or driver and 3 wood, as my ball flight is a slight draw to straight with both. Are there any drills on the site that would help me slow down the iron rotation? Thx very much.

Craig (Certified RST Instructor)
Hello William. I don't have any drills specifically for the over rotation issue. But, I would would on impact shots from the 5 Minutes to the Perfect Release and you could use the 9 Days to Amazing Ball Striking Section (Low and Fade) to get better control of impact issues.

Hello Walter. Thanks for the compliments. Controlling the lead thumb is tough. It is all about practice and gaining good awareness for when it is pushing. Work on the 2 Finger Release Drill to keep focusing on turning it off.

Clay, I've really enjoyed your 7 part series, very informative. I would like to make sure that I understand your face contact explanation. You are saying that a shot hit from the heel creates a slice and a shot hit from the toe creates a draw? Surely a ball hit from the heel of the clubface will close the clubface, therefore sending the ball left initially (right handed golfer) and vice-versa for balls hit from the toe.

Craig (Certified RST Instructor)
Hello Alvin. I am happy you are enjoying Clay's Video Series. Yes, the heel will be more prone to the slice and toe the draw. The gear effect happening at impact causes the confusion. For the heel, the club face will close but is putting opposite spin on the ball (closed face, but slice spin). Doesn't sound like common sense. If you Google Gear Effect. Take a look at a few images. Will provide a better picture in your head.

Hi Craig, thank you for your quick reply and I researched as you suggested. The gear effect theory is based on the assumption that the club head is creating side spin on the ball. I thought the d-plane theory dispelled the fact that the club head can create side spin, only backspin and the axis changes (similar to a plane).

Chris (Certified RST Instructor)
Hey Alvin, you are correct with the axis changes in regards to d-plane. Depending on the path and the position of the club face during an off center hit, will determine how the ball flies. Trackman has a pretty awesome data chart that shows you exactly what happens during off center hits and how the path and clubface angle will dictate the ball flight.

Where should the club face be relative to the ball at address ?

ideally right behind the ball with the ball in the center of the face.

Overall good stuff. However you need to be careful about bandying the term 'gear effect' about in relation to irons. Gear effect comes into play with woods, not irons do to the location of the center of gravity. http://www.tutelman.com/golf/ballflight/gearEffect.php
