In CrossFit and in life, we go overhead. Kelly Starrett, of San Francisco CrossFit, explains the essential anatomy and physiology of the shoulder in this excerpt from his one day seminar at CrossFit Santa Cruz on November 9, 2008.
The shoulder is designed primarily for mobility. There are a number of forces that rotate it internally, while there are relatively few forces rotating externally. Balancing the shoulder so that it remains in an optimal position for maximum stability and force production is the goal.
This is the continuation of the series from Kelly on the theory and practice of stabilizing the midline in functional movement.
