Someone said, way back in the thread, that it wasn't a problem having the head move away from target in BS, so long as the hips don't sway with it. Is that the case or is it important to keep both my head and hips from swaying back on BS, and if so, why and how can i learn to keep my head from swaying forward with my hips?
Ideally you want to keep your head steady and not have the hips sway back to the right on the backswing. Having said that I would rather have a player move their head a little to the right (hips centered) rather than towards the target on the backswing.
Check out these drills to help keep the head steady on the downswing but the weight forward.
