Lie on your back on an exercise mat. Your knees are bent to 90 degrees and your feet are flat on the mat. Place your right foot across the top of your left thigh, near your left knee. Your right leg is turned out. Reach through your legs and clasp your hands together behind your left knee. Pull your legs toward your chest. You'll feel a stretch behind your right thigh and in your right gluteal muscles. Relax and return to the starting position. Repeat on the other side.
