Swing within your feet

Golfers who’ve developed "good hands" through years of practice err toward too little use of the body. Less "trained" players try to make up for their lack of hand speed with excessive body action. As you swing, picture yourself coiling and uncoiling so no part of your torso moves beyond the confines of your feet. In other words, only your hands and arms move beyond the outer edge of your right foot on the backswing and the same goes on the downswing in relation to your left foot.
