Instead of hijacking the 'Protruding Scapula' thread, I'll post my question here.
From what I've read/studied, the Serratus Anterior and Lower Trapezius fibres are quite important for scapula positioning/control/posture. Does anyone train them directly as part of their normal program? How?
Thanks for the input. I actually have some shoulder issues so I bit the bullet and am getting physio treatment. My uni has a physio clinic where the 4th years practice under supervision - cheap, thorough and a great learning experience for me (just started studying physiotherapy).
The exercises in the rehab articles here didn't really help me that much: my problems were mainly posterior capsule tightness, anterior capsule laxity, the head of my humerous wasn't sitting in the shoulder socket and my lower traps suck - my other muscles like to take over. Professional treatment/guidance has been very helpful.
I asked the initial question because I'm not sure how much serratus anterior involvement there is during a bench press.. nor how much lower traps are involved during chins/rows. If these muscles aren't involved much in common exercises then could that be why postural issues/shoulder injuries seem relatively common?
Damn dude, you're a mess, but it sounds like you've got a good grasp on the problem; which is key.
The more I've been looking into shoulder balance, the more I see that all these little muscles holding them in place properly are virtually never worked. Right now to fast track my progress for example I've devoted about 20 minutes a day to shoulder health.
