Sit on the floor with your legs together and stretched out in front of you. Place your hands on the floor behind you for support. Slowly bend your right knee, sliding your heel along the floor toward your butt until you feel a gentle stretch in the thigh muscles. Hold for about 5 seconds, and then slide your foot forward, straightening your leg. Rest a few seconds. Do 10 times. Reverse legs, and repeat 10 times.
