To stretch, lengthen andrelax the muscles that twist the upper arm in an outwardly direction. To stretch the Teres Minor and Infraspinatus muscles.
Place the arm of the affected side horizontally across the chest with thumb pointing downward. Using the vertical forearm of the unaffected side, contact the elbow of the horizontal arm.
Using the vertical forearm gently pull the horizontal arm both toward and across the chest until a stretch is felt in the affected shoulder. Hold this position for 20 seconds whilst breathing slowly and deeply. Then return to the start position.
Be sure not to rotate the torso during this exercise as this will lessen the stretch of the targeted muscles of the shoulder.
