It may be because your front foot is squared off (90° to the target) restricting your rotation. Try to flare the front foot open a bit at setup to help create more freedom for rotating. It is critical for your front foot to roll to the outside of the golf shoe (DUPLESSISGOLF Members can watch: Roll your Feet in the Swing Section ). You can not rotate with the front foot flat. If you just throw a ball and see what your front foot does, it can give you an indication of how your front foot needs to be setup for your golf swing.
