I'm doing barbell squats as described in Starting Strength.
When I get to a certain depth, I feel my thigh bone (femur?) pinching up against the inside of my pelvis, and feel like I can't go any deeper. Is my form wrong? Do I stop there? Or do I somehow go deeper?
Note that I didn't feel these before, and was going very deep. But observers told me (correctly I believe) that my knees would go forward too much, or that my hips were going up and down, not back and out. Fixing that (now my squat looks like right) has caused this pinch.
