HOW: Begin by lying on your side with your knees bent up and a block in between your legs. Place your bottom arm on the ground straight out from your shoulder. Place your top arm on top of that arm with your palms together. Rotate both arms up and over to the other side as you rotate only the upper half of your body. The goal is to rotate both arms over as much as you can while your hips remain in the starting position facing the other way. Return to the starting position and repeat.
FEEL: You should feel a stretch in your mid back and torso.
COMPENSATION: Keep your legs on the ground and don’t let them twist with your upper body and back.
