>>16599583That was their ribcage, not their pectoral muscles
OP is right
Joe weider was a fag with a fetish for big chests and started the whole huge droopy chests trend. before that chests were either small or proportionate to the physique itself
Huge ribcage is genetic and can slightly be improved with dumbell pullovers
just look at this german strongman from the 20s, huge ribcage but his pectorals themselves aren't to the levels that bodybuilders nowadays want to achieve
