Movement: Lie on your back and place the leg to be stretched into internal rotation - placing the heel of that leg away from your body while the thigh remains relatively inline with the torso. Gently hook the other leg over the top of the stretched leg and apply pressure until a good stretch is achieved. Hold for prescribed time.
Repetitions: Hold for the full prescribed time on one side, then switch sides and repeat. This counts as one set.
