WHAT IS EARLY EXTENSION?
Early extension occurs when the hips and spine of a golfer start to go into extension or straighten up too early on the downswing. This occurs when the hips and pelvis move closer to the ball on the downswing. Early extension causes the upper body to lift up allowing the golfer to maintain their balance. The lower body does not easily rotate through impact, instead it pushes forward and the person stands up. This will cause players to often complain of being stuck or trapped with their arms on the downswing. The result can be a block or hook as the hands and arms desperately try to deliver the club to the ball. If golfers do not do anything with their hands through impact, they may actually shank some shots because they are closer to the ball than they were at the address.
