405 for 12 is fuckin good, what are you talking about?!
For example my squat sucks, I can only get 405 for 12 or so reps yet 900 for 12-15 is no problem on an inclined leg press. Why the big difference? Granted I've had some issues with the lower back...but I'd rather have a big squat. No one cares how much you leg press anyway.
