Then explain why the guys had smaller legs back then? The best answer anyone comes up with is usually because they overtrained them. And the guys then used a lot of drugs, dude. They just didn't use GH and slin. Don't kid yourself on the dosages. Also they didn't have today's nutritional knowledge down. To them, it was about eating enough protein precontest. Off-season, some didn't even lift or juice. Different era, can't compare to today.
But their arms, chest, back (depending on the bodybuilder), shoulder, forearms, and calves were just as big. Whats your point?
And you just say "they just didnt use GH and slin" as though they really dont do anything lol. GH and slin makes a WORLD of difference.
Fact is the guys back then trained like animals, lots of sets, no GH and no slin, and had better physiques, and all around, besides legs, had equal sized body parts. How do you explain Platz legs, arnolds chest, columbos back. All built with lots of sets and no gh and slin.
No overtraining there!
If guys today werent such lazy sacks of shit and trained and dieted and rested right, they could get away with a lot of sets like the guys back in the day did.
