Ok well before I started the 5x5 I rarely squatted heavy or frequently. Use to get my leg work on leg press, extensions, and so on. Well i found the missing link to make my legs grow, thats for sure! My knees must not be used to the movement. I've been told by numerous educated lifters that my form on the squat is very good. I go below parallel and love it. The problem is my knees. First I had pain in my left inner knee area now I have it on the right side. I don't want to fuck my knees up and i definitely don't want to lay off the squatting. After doing the 5x5 I can't imagine not squatting when going into the gym. It's a way of life now. Any advice would be appreciated.
