This exercise is about rotation, and there are a couple of ways to test this. First, Mike sits on the ground with his left leg bent other the other. He places his right arm outstretched, resting on his knee. His left arm is behind him, and he turns and looks over his left shoulder. Mike can get his shoulders in line with his straight leg. He repeats this exercise with the other leg, turning the opposite way. A second exercise to test rotation is to stand and place the club across your chest and shoulders and then rotate. The key is to turn from side to side and not turn your hips. Mike can also rotate his hips and isolate his shoulders. When Mike swings, there can be a separation between the shoulders and hips, but it won't be easy if you are tight. This is a great exercise to help with rotation in your swing.
