Left Arm Only Swings

For right-handed players the left arm must remain extended from the start of the backswing to the beginning of the follow-through.  A good drill to help feel this extension is to make some swings holding the club only in the left hand. Start with choking down on short iron.  Feel the left arm push the club away, hinge the left wrist and pull the club through on the downswing.  The left arm wont fold until your hands are just about waist high on the follow-through.  Right hand dominating your swing, this drill helps that too!
