Please settle a debate for me. A friend of mine swears that Squats can be bad for your knees. In fact he suggests leg presses instead of squats. I say that if done correctly, squats are not bad for your knees, and that leg presses will do far more damage then squats. Can someone please tell me who is right, there is money riding on this as well, so please be somewhat scientific (if posibble) in your answer. Basically, what I mean is, please don’t reply with “Squats rule!” or something like that.
