workout of the day
Inflexibility in the shoulder results in the forward-of-overhead posture in the first picture. Balance and control here quickly becomes tough with even light loads. The second picture represents the postural perturbation needed to find balance with the same inflexible shoulder. In the third picture, the problem is fixed when the shoulders are pulled back to bring the load over the center of balance without moving the athlete's center of balance forward of the frontal plane.
