Do not allow the arm to move during this exercise. Hold the pressure for three seconds, then relax. Repeat 10 times and switch to the opposite side. Work up to three sets of 10 repetitions. Strengthen the infraspinatus using a small hand-held dumbbell.
The subscapularis muscle works to depress the head of the humerus allowing it to move freely in the glenohumeral joint during elevation of the arm. It also works with the other rotator cuff muscles to stabilize the head of the humerus in the glenohumeral joint, or shoulder joint. Infraspinatus: The infraspinatus muscle originates below the spine of the scapula, in the infraspinatus fossa, and it inserts on the posterior aspect of the greater tuberosity of the humerus.
