Don't know about the 80 sets arm thing but if I remember right he would do 32 reps each set for whatever muscle group he was working, nothing less than that. . He never did direct ab exercises but worked them from the inside out. So I'm assuming that he did those martial arts exercises or Yoga exercises (both muscle control exercises), it was never quite clear what he really did. Got this info from some of the old muscle mags, so there may be a grain of truth about his training somewhere in there. Hard to tell what's myth & what's fact in those old BS magazines (today's are worse). Any way, a metabolism like his was one in a billion, probably had to eat quite a bit each day to keep his bwt/muscle mass up to that high level. Lot's of guy's back in the day would mix dry liver powder in a blender, adding water only. That could gag a maggot.
