Use this quick stretch to get the shoulder action you need to hit bombs.
Take your regular backswing and stop at the top. If you've noticed a serious lack of power in your game recently, you probably look like this (photo, below): left elbow bent, hands in close to your body. You're all arms and no turn, and it's costing you yards.
Try this: Using your left hand only, swing the club back until your left arm is parallel to the ground and straight. Grab the shaft with your right hand about a foot from the bottom of the grip and pull it toward your right shoulder. Keep pulling it until your left shoulder swings under your chin. That, friends, is a proper windup.
Thanks to this easy drill, you've learned how to combine arm swing with shoulder turn to create maximum potential energy on your backswing. Do this on the range when you're practicing with your driver or even on the box during your round when prepping to tee off. It's a great way to remind yourself during play to complete your turn and deliver with authority.
