Early extension is best defined as the hips and spine of a golfer going into extension or straightening up to early in the downswing. Golfers also complain of being stuck or trapped with their arms on the downswing. This is because the lower body has moved into the space where the arms need to go and usually results in either a golfer blocking the shot to the right or hooking it to the left as they use their hands excessively to deliver the clubhead to the ball.
Research has shown that the golfer’s inability to perform a full deep squat or a full hip bend can force a player to early extend during the downswing. Failure to perform these movements generally means that there is stiffness in the muscles and joints in the lower body. These limitations might alter good posture at address and force players to change their spinal posture in the swing. In the TPI screen the overhead Deep Squat best evaluates these limitations. 64% of golfers suffer from early extension.
Practice squatting to decrease your chances of early extension. Try to get your knees aligned over your feet while keeping your heels on the ground. If you are unable to keep your heels on the ground, it is almost impossible to maintain posture during the downswing. The actual TPI test involves doing this squat whilst holding a bar over your head.
