Knee to Chest

Stretches lower-back muscles. Lie on your back, legs flat on the floor. Bend your right knee and bring it toward your chest. Hug it firmly with both arms. You should feel a stretch along your lower back and into your buttocks. Hold the stretch for 30 seconds, then switch sides. Now bring both knees to your chest and hold for 30 seconds. Repeat the entire sequence once.
