The reason I had been looking for an exercise like this in the first place is that I have been really questioning a common approach to addressing scapular stability, which is to give the person some combination of open chain rotator cuff and serratus anterior activation exercises. The reason I’m not a fan is that I just don’t think they work.
Is your (lack of) scapular stability cheating your thoracic mobility?
This morning, as part of this whole scapular stability/thoracic mobility project I’m working on, I noticed something interesting: I’ve been cheating the quadruped rotation exercise. The picture on the left is of me at the top end of my left side rotation range of motion, and the picture on the right is of me at the top end of my left side rotation range of motion after setting my scapulae.
