Hey, I have been working w/ squats for a while, but I never really went below paralell before or going to where the hamstrings touch the calves;always stopped just above parallel and then went back up. So when I started doing that I had to reduce the weight to 135lbs. to get propper form. I am noticing a weird feeling in my knees that I haven't noticed before. It has been already a few days since I last squated and I'm still feeling it. The feeling isn't pain or anything. . .can't really describe it, but I'm starting to get worried. I haven't had any pre-existing knee problems. IS ANYBODY EXPERIENCING WHAT I AM EXPERIENCING? Or is this just normal?
