Chip balls to groove the shift onto your lead foot
To groove the forward shift, get into the shifted position with knees together and weight rolled onto the outside of the lead foot, arms extended, chest slightly up with a slight arch in the lower back, then chip balls feeling your body move through. The aim is to improve compression and low point while stopping the upper body from sliding forward.
