I started squatting a few weeks ago vs. just doing legpress. The first week I did it, everything went fine. Last week I played basketball for the first time in a while, then did legs the next day. During my sets (of squats), I felt a pain in my left groin area (felt like it was related to a tendon, not a muscle). It didn't hurt too bad, so I just worked through it. It did not bother me at all during this past week, so I figured it was just soreness from playing basketball. Fast-forward to today. I was at the gym doing squats and the pain is back, this time a bit worse. It happens only when I'm coming back up and near locking out my knees. I've tried adjusting my stance and adjusting my form, but nothing seems to help. What could it be? Is it that my form sucks and I don't realize it (I'm all about form, so I don't think this is it)? Also, I'm 6'3" and I'm finding that I lean forward pretty damn far when I go down (to where thigh is parallel to the ground). I've tried to not lean forward as much, but it feels like I'm going to fall over backwards. Is it bad to lean really far forward?
