I'm currently going through some training with a military school for promotion and during the school we PT every day. I'm already used to working out (doing a 5x5 right now) and other than being about 10lbs overweight and recovering from a lower back injury (happened several months ago, I'm fine now and back to doing BORs, SDLs-just not at near max weights yet, I'm taking it slow) I'm in pretty good shape. I had stopped running though for a while because of some inner/medial knee pain on my L knee that basically I chalked up to me just being too damn heavy (gained weight from my back injury, I'm close to 200lbs and I like to be usually around 185 or so). Anyways, so we went running yesterday and sort of had an "unofficial" PT test. I maxed the push ups and sit ups like usual, and then we did our 1.5 mile run on the flight line of all places. So, running on concrete in high Montana winds really sucked, but I still managed to out run everyone in my class. Part of the reason why I'm positive I outrun them is that other than being a formerly serious runner I also do squats, DLs, and lift seriously. But again, that nagging knee pain on my Left knee popped back up. Its only on my left knee, right on the inside/medial side. I just came off a long lay off from running, so its obvious that it is "rested", but the pain is still there but only when I run. I can tell that my left knee is less stable than my right knee, not like its going to buckle or anything crazy like that, I can just tell. That's why I think I need to target the vastus medialus. I can squat around 200lbs for 5x5. Nothing that impressive I know, but still way better than most runners. So how do I do this? Frankly (and I know this is blasphemy on this forum) I don't think that squats and DLs are the answer. I already do those. When I squat I go ass to ground, toes slightly pointed out, and I keep a slightly wider stance than conventional squats anyways. I know I'm not near as strong as most of the lifters on here, but compared to most runners I'm pretty strong. I'm definitely no little skinny ass Ethiopian looking guy. It seems like things like step ups mostly target the outside of the knee or the over all knee, what I am looking for are ways to target the inner knee. Any help would be appreciated.
