Why is this so hard? I can do back and front squats okay and feel good about my gains there, and can do all the overheads I want with a dowel, but as soon as I try it with a 45# bar, my back stiffens up and I can barely go down with cocking my knee out and the whole thing is pretty ugly.
Is it a simple issue of too much weight? 45 lbs just doesn't seem like all that much. My back is very stiff doing this, could it be a flexibility issue?
