The Pectoralis Stretch over Ball stretches the chest muscles that tend to pull you into a forward shoulder, slumped posture. It is important to stretch the pectoral muscles to decrease the stress on your neck, shoulders, and thoracic spine.
Get into a comfortable position lying on your back over an exercise ball with your feet and knees hip width apart, forming a bridge position over the ball. Ideally, your knees, hips, shoulders, and head should form a straight line.
Bring your arms up and out to the side so that your shoulders and elbows are bent to a 90 degree angle. Allow the weight of your arms to help you stretch your pectoral muscles across the front of your chest. You should feel a pulling sensation across the front of your shoulders and chest, but you should not feel any pain in the front of your shoulders. Stop the stretch if you experience any shoulder pain.
