last year I ripped a groin muscle and couldnt do squats and any lower body with out my balls feeling like they were going to explode for about 6 months. when it was healing i started slow and now finally a year later i built it up to be able to do as much weight as i can with no pain. but now my upper body is a lot bigger than my lower body and i need to bring my legs up. so what can i do to get them to catch up to the rest of me
