Your shoulders are the most mobile part of your body and they are involved in almost every movement you make. Thus, having strong shoulders is not only important in performing the activities of everyday life, but also in the prevention of injury and pain associated with weak shoulder muscles.
Your shoulders are made up of muscles that are primarily involved in the movement of your arms to the side, to the front, and to the rear of your body. Simple put, the muscles of your shoulders can be divided into three heads, and they are lateral, front, and rear. It’s crucial to strengthen the muscles of all three heads of your shoulders for optimal strength and injury prevention.
In the video below I demonstrate one of my favorite exercises for developing and strengthening the muscles of all three heads of your shoulders. Additionally, you get the benefit of strengthening your core, and improving your balance by performing this exercise while standing on a BOSU.
