2. Move into a deeper stretch by grasping your hands together under your right leg and cradling your ankle and knee in your arms. Be sure that you sit up tall. Do not round or hunch your back. Concentrate on relaxing the right buttock muscle as your bring your leg closer to your chest. Hold this position and breathe for 20 to 30 seconds. Lower your leg and repeat on the other side.
