Apply Back To Normal Arnica Cream™ to your chest near your shoulder and underarm.
Stand next to a corner or doorframe, with your feet shoulder width apart and your hand on the wall, palm facing forward
Turning your hips and shoulders together, rotate your body away, so that you feel a stretch across your chest
Rotate from your hips during the turn and keep your feet in the same position throughout the stretch. Let your elbow relax and remain bent.
