I am on stronglift 5*5 and as the weight is increasing with each workout, squats are getting challenging, while the program is really good, I want to keep doing it and avoid any injuries. The other day after squatting I felt some pain in my left shoulder, it got me worried about my form. After watching a few videos, I think my bar position might be causing this pain.
The Mark Ripetoe Video says that the elbows should come back to create that shelf with the posterior deltoid, while this video by OmarIsuf very clearly demonstrates that elbows should be inline with the body.
My question is how do I figure out what is the correct bar position for me? And how does it feel when the bar is correctly positioned.
Another complication is that guys in these videos have fully developed deltoids so they can create that shelf very easily, I am very skinny with almost no deltoids, so it hurts my bones with the weight gets heavy and is wrongly placed. As it had happened while doing high bar on local trainers advice. So please tell me how to perfect the low bar squat.
Thanks!
