Every good golfer knows that power comes from the body , not the arms. To learn to power the club with your body instead of your limbs and hands, put the club behind the ball at address, with your body in a dead-stop position. Without taking a backswing, try to drag the ball into the air. If you’re a player who use his or her hands to control the club, you’ll probably struggle at first. However, you’ll rapidly find that once you start moving the club with your body, you’ll begin to get the ball in the air more consistently. This helps you turn fully through the ball on the downswing.
