I squat really heavy twice a week. My question: is squatting really heavy twice a week bad for you. I have a bit of a patellar tendonitis in my right knee too. I also started to get a achey left knee. I talked to Greg Everett on fb and he said I'm not taking care of myself, things like foam rolling and warming up properly. I usually do 3x5 at 275, 295, 315. Should I also be taking joint pills too.
