I seem to be having some problems with squatting lately. In the past few months I have gone to using a slightly wider stance, and placing the bar lower on my back than I used to. I can definitely move weight much easier this way and hit depth better so I really like squatting this way. Only thing is my hips have begun bothering me doing this, to the point where I can't go above 315 even without my hips beginning to hurt. I really enjoy powerlifting, and squatting and would feel extremely inadequate if I could no longer squat in meets (jk of course..well kind of). Does anyone have any suggestions for things that I can do to help strengthen my hip flexors? I have been doing a lot of stretching for them, and rolling out my hips on a foam roller but it's not really helping that much...
