I said I would talk about this again and I am going to make it really simple.
It’s about two things. Your turn never stops except in the transition and your spine/head don’t change positions.
We can put different labels and feels on this, but that is the gist.
I will give a few practical examples and as usual, not a comprehensive list.
When getting in front of the ball, the head/front shoulder/spine move toward the target to start the downswing. This not only changes the spine angle, the whole time your body is moving toward the target, the shoulders will not turn.
When hanging back, the spine/head move away from the target to start the downswing…or the spine tilts more behind the ball to start the downswing, often causing the rear knee to collapse.
I’ll make it even simpler. If your head doesn’t change position to start the downswing, you are probably OK.
Like most things in golf, be careful of the opposite extreme. Trying so hard to keep your head still that you lock yourself up.
As long as your shoulders are turning around your spine to start the downswing, neither of these problem will be much of an issue.
I’ll do a video and have a few drills next week to clarify.
EDITED: I can see by the comments that I need to clarify. I am not talking about subtle movements, nor the slight adding of tilt in the transition. I am talking about obvious and severe moves. If the move is subtle, as I said above, we are not into any of these issues.
It’s all a matter of degree.
