Lie on your back with your legs extended and arms at your sides. Cross your left arm across your chest and slowly roll onto your stomach.

Keep your right arm in the same position across your body. As you rotate, press your chest on the ground with your right arm across your body.

Reach your left arm overhead stabilize this prone position. This will increase the stretch in the posterior shoulder capsule. When you're ready, roll back to the supine position and switch sides.
