you dont have to squat 600lbs to get good legs..................im tall, i already slipped a disk or two in my back, so i got to watch what i do..............
smith machine squats are the way to go.................moder ate weight, nothing crazy...............but feel the motion, really feel you quads and hamstrings contracting........hi reps help alot too.
oh yeah, and 800mgs of upjohn Cyp a week.................... ...legs will be growin' in no time.
