Well, I am basically just re-watching the videos that you sent me in the original post. The main issue is that I have consistent knee pain while squatting with an arch. It’s not any part of the quads, or any muscle related part of my knee. I have since bought orthotics for my shoes. It’s a moderate improvement, but any improvement seems like I just won the superbowl. There is no knee pain from any other movement. When I practice body weight squatting alot, I notice that I ahve alot of knee pain when i try to arch my foot in the way Kelly advocates. I am probably just post footage from now. This week I will do just that with a bar.
