In Destin I learned that my head moves significantly to the right in the backswing, causing too much hip slide going back and all sorts of problems, including difficulty in performing a proper extensor action.
So I am trying to re-program for a stationary head. The only off-course drill I have been able to come up with is to rest the right side of my skull to the doorblade of an open door, putting a ball in the right spot on the floor and swinging back without a club. It gives me a new "perspective" on where the ball should be in relation to the head and a new feeling for the backswing move. Also the door moves if the head moves.
Still I am able to do some "hula hula" at the same time, which is also good.
Obviously there are some drawbacks since I am unable to do this with a club and/or plane board. The closet or door is in the way.
So I wonder if anyone has come up with other ways of "programming the head" to be stationary assuming there is no one around to help watching your head is not moving.
