Here's three videos of me doing my current 5 rep max on the starting strength program (top down view, side view and front view) . Problem is now my front shoulders seem to be doing most of the work and i don't know why. I'm pinching my shoulders and trying to keep my elbows tucked in more. But my front delts give in way before any other of my muscles do causing me to stall.
*edit* it's mostly in the left shoulder the right is either fine or non-noticable.
