I emailed you a couple weeks ago, then never posted. Here's me not being lazy any more, since I didn't resolve the problem...
I'm having some pain in what I assume is the quadriceps tendon. My knees hurt after squatting (pretty much all the time now) right at the top of my patella. I feel this when I'm extending and flexing my knees (I just did some body-weight squats and they hurt), and when I press on the very top of the patella (right at the angle), there is local pain.
I just posted the following video of my squat, and PFerrari pointed out that my knees are too far forward.
I've heard about and tried to fix my knees-forward problem a couple of times. I'm wondering if I just have long femurs and therefore I can't get my knees back, or if there is a cue I can use to help this out. I'm also wondering if my knee pain is due to the knee position.
