I think if you do all the different types of warm-ups (I think the book discusses 3 different types), which include exercise-specific warm-ups, and are experienced enough a lifter to be handling really heavy weights, an hour or longer is probably not unrealistic. I don't know if cynic's avatar is really a picture of him, but to be able to be that muscley at that advanced an age (just kidding) gives him the right to take as long as he wants
