HOW TO PUT SHOULDER FLEXIBILITY TO WORK FOR YOU
From testing thousands of players we've found that good golfers keep their left arm straighter than less-skilled players during the backswing and downswing. One of the reasons why good players are able to do this is that their right shoulder is flexible enough to support the left-arm extension (when your right shoulder can no longer support it, your left arm bends). If you have a quarterback's arm, make a conscious effort to keep your left arm as straight as possible on your backswing and on the way back down. As you swing to the top, fold your right elbow to support this action.
