Adam, I squatted 385x5 this morning...but you're like half my size and one of the few people here who could literally kick everyone's asses, so yes, quakes, tremors, etc.
Hey go easy on the knee, Mark. I hurt mine last year and it was nowhere near as gruesome as yours, and it still took me a long time to come back. For months my hips would slide over to the good leg during squats, and even know, my good leg is noticeably bigger than the bad, and on grinder reps, the hips still slide over. I found that the best thing for me was not squats but walking, running, and prowling. I have no idea why this was the case, but it seemed to remind my body that the bad leg was still there and should be used? Iono. This sounds super broscientific and like PT-talk, but hey, it's what happened. So what exactly is going on with your knee now?
