Yoga Anatomy: 4 Steps to Facilitated Shoulder Stretching in Gomukhasana
Today’s post illustrates some of the shoulder biomechanics in Gomukhasana (Cow Face Pose) and some simple steps that can help to increase the range of motion of the lower-side arm through a facilitated stretch of the shoulder external rotators. Please note that persons with certain conditions of the shoulder, including arthritis and instability, should avoid extremes of range of motion (as in Gomukhasana), as this can aggravate their condition. Always, in your particular case, consult your healthcare provider before practicing yoga or any other exercise program.
The Basic Science
The shoulder is the most mobile joint in the body. It is actually a combination of four separate joints: the glenohumeral, acromioclavicular, sternoclavicular and scapulathoracic joints. All four joints contribute to shoulder movement in a “coupled” fashion—that is, movement occurs via a combination of individual joints. Limitation at any of the joints forming the shoulder can impair movement.
As with all of the articulations in the body, mobility and stability of the shoulder are determined by three factors: the bone shape, the capsuloligamentous structures, and the muscular stabilizers. The majority of shoulder movement is from the glenohumeral joint. This is a shallow ball and socket that is held in place by a capsule with ligaments and a series of muscles.

How to Deepen Shoulder Flexibility in Gomukhasana
This practice focuses the drishti on the lower arm in Gomukhasana and uses a facilitated stretch of the infraspinatus, teres minor, and posterior portion of the deltoid to allow deepening of the pose. A belt connects the upper and lower arms.
These steps are repeated once to deepen the stretch. Do not attempt to attain your maximum in one practice. Rather, build your flexibility over time with consistent, gentle practice.
The key to this technique is to press the back of your hand into your back while drawing down against the belt. Gradually increase the amount of force you use to press the hand into the back and do not exceed 20 percent of your maximum. This is a facilitated stretch. It works with the Golgi tendon organ to create relaxation of the muscles that are stretching in the lower side shoulder. Use the upper arm to gently draw the lower arm further up the back.
