I am 6ft4in myself. I just started squats this month. They kick my ass... leave my muscles very sore. But this is only because I haven't been doing them. Done properly they won't fuck with your knees or back or anything. I use a squat-rack. I can't squat very much (yet) but as I continue to eat right and train right my numbers will go up.
Don't use your height as a crutch. What is a few extra inches!?
