CHRIS TOULSON demonstrates how the speed of the swing and length of the finish play key roles in controlling distance
Shanks occur in the one plane swing because your arms are too far out in front of your body so concentrate on bringing your hands in closer to your legs on the downswing.
Use your right forearm to turn as you go through while the left arm is folding in. Make sure to maintain an arc in your swing as this short swing still requires a rounded swing path.
