Lie on your back on an exercise mat. Bend your right knee about 90 degrees and place your right foot next to and outside of your left knee. Reach across and place your left hand on the outside of your right knee. Using your left hand, drag your right knee downward to the side and upward toward your chest. Be sure to keep your lower back flat on the exercise mat. You'll feel a stretch in the outside of your right gluteal muscle and upper right hamstring. Relax and return to the starting position.
Repeat on the other side, placing your right hand on the outside of your left knee.
