The scapula is one of the least congruent joints in the body. There is no bony articulation between the scapula and the thorax. This is why the scapula can move so easily, essentially it is a free floating bone that can move into protraction/retraction, elevation/depression, anterior tilt/posterior tilt, internal/external rotation and upward/downward rotation. This video will help you visualize scapula movements. We can not change the structure of this scapulothoracic joint, however we can improve scapular control! Scapula position is almost fully determined by the pulling of muscle groups that attach onto the scapula. The scapula is the core of the upper body, this is where force comes in through and gets distributed out of. This article will demonstrate exercises that you can do on your own to improve your scapula control.
Serratus Anterior, which is also known as the “Big Swing Muscle” or “Boxer’s muscle” due to its effectiveness of protracting the scapula. Not only does this muscle have a cool name, but it is also needed for a plethora of arm movements; weather open chain (punching/grabbing something out of the cabinet) or closed chain (pushups, planks, downward dogs, or handstands). Due to its large role in stabilizing the scapula, inadequate strength here is often the culprit of Scapula Winging. This article will demonstrate a few exercises to improve activation and control of this Scapula Stabilizer in open kinetic chain.
