Not all low right shoulders are what they seem.
In baseball a low right shoulder on a right-handed pitcher often gets read one way: a byproduct of throwing, the same in everyone, addressed the same way. It isn’t the same thing. What it means depends on structural bias, and treating every low right shoulder the same is shortsided.
On a narrow, the low right shoulder can be a right-sided compressive strategy. It’s not acquired relatively. It’s how the narrow holds the base of support against the body’s rightward drift. The narrow carries an ER bias, so posterior compression is the starting point, and anterior compression is the reciprocal response to it. Sequentially this works top down. That anterior orientation is what you see at the shoulder: forward center of gravity, loss of IR, bends and twists that leave a visual look to the scap being positioned forward and down.
When the go to response is to row more, drive shoulder ER, etc. you add posterior compression on top of the posterior compression that is already baseline. The reciprocity means the anterior compression you were trying to resolve only deepens.
On a wide, the low right shoulder is likely not a compressive strategy taking hold. It’s often the oblique right turn itself. The left unweights, which raises the left shoulder, the right sits relatively lower as it takes on more IR. The right shoulder is relatively lower, than the left. The wide’s order is reversed from the narrow’s: anterior compression baseline, posterior as the initial response, sequencing from the bottom up. Play the wide’s relatively low right shoulder as compressive bending and twisting… and you’ll often find your lost in the sauce.
The assumption that the shoulder is a held compressive adaptation is closer to true on the narrow than the wide. However, in any context…it would be best to have diagnostics to place better bets. Treat every low right shoulder the same and you may not be successful: or maybe worse mislead as to why when things do work out.
