Only saw Rosbo when out restaurants etc ..he trained at different time...guys at Golds said he was a tank..curled 225 like a piston....guy had forearms and hands size of tree. Everybody did tons of sets back then.....in the words of the Barbarians" no such thing as overtraining...just undereating and undersleeping"...gotta remember to no GH, no IGF-1,no slin back then
