Hi! Not to overstep but if it’s allowed, I’m also happy to help. I have a doctorate in physical therapy with an ortho specialist and ten years experience- even I had some knee pain from the increased load lol. A lot of knee pain is compression on the knee cap from tight quads/it band. Roll the heck out of your quad and ITB daily. Look up ‘kneeling quad stretch with back leg up’ (you need a pad to kneel on), look up ‘McConnell taping’ to help pain during activity, and reverse Nordics are usually well tolerated for a great quad burn without pain once your symptoms improve (esp as a sub for sissy squats).
