Of course 5 X 5 advocates GOMAD too. I think it's patently absurd to imagine that anyone, even kids have to gorge on calories to gain appreciable muscle. My son sure didn't. Rippetoe is a goofball on this particular count and there are respected trainers who are not afraid to blaspheme him on this (and probably some who are afraid to).
Moreover, my son never, ever squatted ... and his quads blew up. He deadlifted, on average, once a week and probably did leg press even less frequently than that. Any BTW, guess who does leg presses ? That's right, the world's top bodybuilders.
So, FWIW, I'm calling BS on 'have to squat' and 'have to stuff your face' to get jacked and strong.
