1. Lie on your left side and stack your knees and ankles on top of one another. Extend your left arm onto the floor and place your right hand on top of the left.
2. Lift your right arm and twist your torso toward your right side. Lower your right arm as close to the floor as you can manage, feeling a stretch along your back. Keep twisting back and forth, from left to right. When all reps are complete, lie on your right side and repeat the stretch, rotating to your left.
