1. PALM WEAR: Your hands may be slipping during your swing, or you may be holding your club with your palms rather than your fingers.
2. HEEL WEAR: You may be re-gripping at the top of your swing, or you may be holding the club too close to the end. Check that you are gripping the clubs about an inch from the end.
3. THUMB WEAR: You may be extending your thumb too far down the shaft. Point your left thumb slightly toward the right for a more natural, comfortable backswing.
