On 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.

Mark RippetoeThe 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 RippetoeYou are right to be wary. There is much bullshit. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic.
Mark RippetoeI was driving home the other night, listening to the radio, and the guy filling in for Art Bell on Coast to Coast AM was talking to some other guy about Nazis, UFOs, the Kennedy Assassination, time travel, and George Bush, and how it all relates to OneWorldGovernment. This, of course, made me think about barbell training.
