I'm so used to squatting with the high bar position but I keep reading articles and opinions saying that the high bar position just does not give me the full benefit of doing the Box Squat. Even from videos and images I still don't get it, is the bar supposed to be on the area right under my shoulders? Wouldn't that put the weight right on my spine?
I've gone through a little trial and error and put the bar a little below the edge of my shoulders but that feels so awkward and I can never seem to finish my heaviest set without failing (but with high-bar, no problem). My left hand and shoulder feels pretty strained too, is this due to lack of shoulder flexibility? I'm already doing dislocations and doorway presses every day just to get a better feel for the low bar position.
