an old wives' tale that ignores the mechanics involved. the greatest torque that endangers your knees is right at 90 degrees, and if you try to stop at 90, that makes it worse. you can't do nearly as much weight if you go below 90, so you're actually putting less strain on your knees all the way through the motion. i'd be much more worried about stressing the knees on some of these really big leg presses some guys attempt.Hockey Playa said:yes im am also curious of benefits of 20 reps?
BTW i thought squatting past 90 degrees was bad for your knees:
the 20 reps are simply to wear out muscles that are able to take a lot of abuse. if you tried 20 reps at your true 10rm on small muscle groups, you'd tear them apart, and I don't mean in a good way.
