I remember he was always advocating for activity. Keep moving, stay active, keep lifting, minimal rests between sets, he did so many sets and reps with little rest it was an aerobic workout with weights. I'm paraphrasing but thats how he described it.
He compared the modern bodybuilders ( modern in 05, 06, 07, 08, 09, 10 etc) to caged chickens and cattle being bulked up on hormones and feed.
