Start this exercise by laying on all fours. Your arms should be in a straight line with your palms flat on the ground. Keep your back straight and bend at your knees so your legs come straight back of you. Your knees and toes should be on the ground.
Take your right arm, and place it on a stability ball so that your arm is bent at a 90 degree angle and your forearm is resting on the stability ball.
Allow your body to drop while keeping your arm on the stability ball. Drop in a slow and controlled motion until a stretch is achieved. Maintain the pose for the allotted amount of time and then switch sides.
