This is a great drill if you are having trouble with your shoulder turn. First get in your golf posture, then take a club and put it accross your chest, with the club head on the same side as your backswing. Hold the club accross your chest by crossing your arms. Then in your golf stance pretend there is a golf ball you are going to hit, make a backswing and make sure the butt end goes to the ball, on the forward swing make sure the club head is square to the ball. This drill will help you with your shoulders through the golf swing.
