How to Add Power and Speed
Back in Step Five we emphasized the rotation of the shoulders, and we said that while you should work to increase the comfortable range of your shoulder turn, you should only gradually try to put the greater turn in your everyday swing. The same is true for the arm pivot on the upswing. This pivot is the amount the arms move around the swing plane in addition to the shoulder turn. Jaidee Thongchai is actually one of the Top 100 golfers who uses relatively little arm pivot. Even in his swing (below), however, you can see that the arms move more than the shoulders, changing the angle formed by the back and the left arm.
