If you feel like your neck is leaning forward and the shoulders slightly rounded this is the movement for you. The “Side to Side” addresses the Latissimus Dorsi, Sub Sapularis and Pectoralsis Major and Minor.
This movement, the “Back and Forth” focuses on taking the shoulder muscles through their range of motion (ROM). By doing so , you may feel stiff and the movement unatural. Begin with the hands wide apart and low intensity. This movement should be low intensity and easy to do. It will retrain all of the shoulder girdle muscles to be balanced and improve your posture.
