Can “not-shrugging” in the Press contribute to shoulder impingement?
Greetings everyone.
I just want to ask whether not shrugging in the Press can contribute to shoulder impingement (i.e. the head of the humerus hitting the bony protrusion of the scapula).
I just finished a set of high-rep Presses today (I know, I didn’t do fahves) and felt an impinging sensation in my left shoulder at lockout. Granted, I forgot to shrug at the top (or had a “weak,” incomplete shrug) at the later reps.
As far as I understand, when we move our arms overhead (prior to the shrug), the scapulae already freely rotate upwards, so impingement isn’t really possible. The shrug at the top serves to reinforce their upward rotation and elevation, but it isn’t “necessary” per se from an injury prevention standpoint.
However, my experience today suggests otherwise. Could it probably be due to the way my acromion is structured (i.e. having a more pronounced protrusion)?
Sorry for the wall-of-texty post. Thank you, I appreciate you guys’ inputs!
