This exercise is a great way of decreasing the tension of the pec minor muscle, allowing the shoulders to roll back to a healthier posture, and decreasing any tingling and numbness in the arms that may be present. Do this exercise on a daily basis to fend off forward shoulders that ultimately lead to hunching of the upper back.
Step 1: Stand up. Move away from your desk.
Step 2: Raise your hands so that your elbows are bent at a 90 degree angle and your upper arms are parallel to the floor.
Step 3: Step into a doorway so that your forearms rest against the door frame.
Step 4: Put your feet together in the center of the doorway.
Step 5: Gently push your hips forward until you feel a stretch in your upper chest and shoulders.
Step 6: Hold this position without bounding for 30-45 seconds.
