The shoulder joint is the joint in the human body with the greatest range of motion. To keep the shoulder joint stable, we have the wonderful rotator cuff, a group of small muscles below the armpit and shoulderblade. Sadly, these little muscles are ofter under-developed, leaving the shoulder unsupported and prone to pain and dislocation. This little sequence is very healing for shoulders. I learned it from Claude Maréchal, the head of the Viniyoga lineage in Europe. But, the shoulder-drop to the floor with the arms at vertical is pure Rachel...my little contribution to the sequence to make it more healing...Try to do this six times, twice a day.
