Navajo Tom isn't too insane. Expectations and reality are different for everyone though. But I find it pretty easy to get sub 150lb novice women to 200lb squats, 300lb deadlifts, and 100lb benches in the same timeframe he mentioned. But I know how to do what I do and how to get the results out of all sorts of personalities. Males in the age range and athletic potential that he most likely associates with, with the atmosphere they have going on, could get pretty far in a short period of time.
