the shoulder is really stabilized by not a true ball and socket but rather by these four muscles that make up the rotator cuff the muscles are Terry's minor infraspinatus supraspinatus and subscapularis
The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

so we've got the supraspinatus and the subscapularis there there's two other muscles that make up the rotator cuff I think everyone's heard of the rotator cuff yes and yet it's probably not obvious to people that it's it's really for muscle right that are doing this what are the other two so the other two are the infraspinatus and the teres minor
it's not normal that we usually look at them from front and back but the bird's eye view is what allows you to see how the subscapularis and the infraspinatus are stabilizing the front and the back while the supinatus is coming in over the top
