I love reading these numbers of the classic bodybuilders, and comparing them with today's, which are usually something like:
Offseason Weight: 278 lbs.
Competition Weight: 236 lbs.
Those guys back then had 6-packs all year round. The Professor will pounce on me for this, but that's what I think the essence of bodybuilding is: You are muscular, and you are lean. You may be leaner at certain times (for contests, if you're a competitor), but you should always have a 6-pack.
If only I could make this work for me...
And I second the person who said Serge had great pecs. I like them more that Arnold's too.
