The rotator cuff muscles stabilize the upper arm bone to the shoulder socket and allow for a wide range of motion in the shoulder. Often times these muscles are weak, overstretched, strained, and even torn. In yoga practice, the repetition of Chaturanga Dandasana with the arm bones out of alignment can be problematic. Whether or not you have a strain or tear, this exercise, as taught by Stacey Rosenberg, is a fantastic way to strengthen your shoulders and provide the support you need in your yoga practice and your life.
