I have always had a problem with this. When you don’t play and get under a little pressure, old habits have a way of finding themselves back into your grill.
Obviously hanging back is bad and no one wants this, but when your head/front shoulder move toward the target to start the downswing, in inhibits the shoulder turn and gets things out of sync.
I especially get caught in this when trying to keep the ball flight down.
I am going to do a video on this next week sometime. If any of you have trouble with this, don’t feel shame. Many golfers who used to have a reverse pivot/weight shift often develop this problem.
