The Chicken Wing is one of the most obvious things that people will see when they watch their golf swing in video.  Then off to the range to try to fix it, right?
This is the most common reaction and error when seeing the Chicken Wing.  However, many don’t realize that anything you view in the golf swing is merely a reaction or a result of a previous movement.  For instance, downswing, leads to impact, impact leads to follow through.  Anytime you want to fix Anything, you should always look earlier in the swing for the root of the cause.
