Squatting "ass to grass" is retarded
First of all let me say that I DO squat and can put up 185 for 6 ass to grass and I HAVE tried it and that doesnt change that it is retarded because it is bad for your knees. I When you squat ass to grass you use less weight than you would on lets say a quarter squat which mean less weight on your quad fibers. Just putting 315 on the bar and holding it will produce gains because you are training your frame to withstand pressure which trains it to accommodate things like lets say huge arms. Most importantly it IT IS BAD FOR YOUR KNEES! When you quarter squat you spending less time with the weight on your knees and saving your precious cartilage. If you want big quads to leg extensions, if you want ham strings do ham string curls, if you want calfs then do donkey calf raises but stop acting like an ass to grass squat is going to work all those things, that is just a cop out.
