Upper trap yes if your shoulder is truly winged (like my right side) but NEVER levator scapula!!!! The real problem is the serratus anterior. Its not simply shoulders being elevated or depressed...its their rotation

Why would he mention lats and levator but not lower traps and s.a?

there's research on this all over the net, just off the top of my head:

Ive stretched my brachial plexus to death (aka cyriax test) what most people have here is downward rotation syndrome. The levators and lats and pec minor turn on bc theyre doing work that the lower trap and serratus anterior should be doing. Theres real winging and pseudo winging. I wish i was a pseudo winger

Dr evan osar has tons of information about this and hes spot on.

I agree tho you cant do any strengthening if your fascia and rib are jammed in the wrong position
(Or something systemic like my mg deficiency)
