The Most Under Trained Muscle of The Shoulder and How to Strengthen It
The Rear Deltoid
The Deltoid muscle is a large muscle that surrounds the shoulder shoulder joint and is involved in most motions of the shoulder. It has an anterior (front), middle, and posterior (rear). While common to see training programs that focus on the anterior and middle portions of the muscle, the rear deltoid is most commonly left out.
The rear deltoid is the most under trained muscle of the shoulder. A weak rear deltoid leads to an imbalance in shoulder motion and contributes to chronic shoulder pain.
