FAULT: SLIDING AHEAD OF THE BALL AT IMPACT
Sliding in front of the ball can be one of the more damaging swing flaws, but one of the easiest to fix. This occurs when a player shifts their upper body in front of the ball before striking the ball at impact. This will usually cause some compensations, such as hinging of the lead elbow as pictured above. This leads to a weak shot and very difficult to control the angle of the clubface that dictates where the ball travels.
FIX: LEAD ARM BAND DRILL
Place the band around your body and your lead arm. Take a couple of swing and notice how the lead elbow stays on the body longer and also notice how the clubface releases with the toe of the club pointing towards the sky. This drill will address how the lead arm works in a proper release. Also, when you are using this drill notice how your head will stay over the ball during impact and by keeping the elbow closer to the body this helps you to rotate and not slide in front of the ball at impact.
In this drill you are simply pulling the lead leg back before you hit the ball and then hitting a few 3/4 shots while maintaining your balance in the finish. This is a great drill for players that slide forward during the downswing. Most of the reason of why players slide forward is due to the lack flexibility in their hip flexors and hip area. This drill will not only allow you to rotate forward, but also help stretch the hip area and give you some additional flexibility to rotate during impact and not slide.
