My favorite short game training aid is the Golf In Sync. It gives the necessary feedback to train the golfer to use the shoulders to move the arms and sync up the movements. I have been using it for almost 10 years and in that time, I have seen people that had the yips and poor wrist/hand control become confident with their short game. Golf In Sync is a versatile tool and can be used for all aspects of the game from putting, chipping, pitching, bunker, to even full swing.
