The full squat is a perfectly natural position for the leg to occupy. That's why there is a joint in the middle of it, and why humans have been occupying this position, both unloaded and loaded, for millions of years. Much longer, in fact, than quasi-intellect ual morons have been telling us that it's 'bad' for the knees.
Mark RippetoeI don't even like Greg Glassman. I don't have a cult like allegiance to the guy. I really don't like him. He's too hard to get on the phone and he doesn't drink my kind of scotch.
Mark RippetoeOn resting in between reps: It varies with the length of the set. 5s or fewer get a breath to reset. Longer sets might take 2 breaths. During the last few reps of a true 20RM squat, just do what Jesus tells you. Trust me, if you do an honest 20 rep program, at some point Jesus will talk to you. On the last day of the program, he asked if he could work in.
