One of the best drills to increase range of motion in the hips. On the downswing, we need to have the ability to internally rotate the lead hip in order to use our lower body for power and avoid swing faults such as early extension. Squeeze the yoga block and move the lower legs away as best you can. This is not a drill with a large range of motion and warning, you may cramp doing this! One set of 15 reps.
