Yes.
Hes not full of shit, those guys were far from druggies back then and Reg busted his ass to get the lifts he did. 500lb bench press, 225lb barbell curls, 185lb incline dumbbell bench presses, 600lb squats. Guy had a huge frame was strong as hell and came from an athletic background with a hard working competitive spirit and desire to get big and strong. Completely different mentality and fundamentals than the guys today pumping themselves full of drugs trying to earn a living wearing a thong because they're too lazy to work a real job. Reg didnt do this for money or fame, he was a successful businessman who trained only for himself. Im telling you the guys back then were a different breed and had totally different intentions, motivations and outlooks on what the pursuit of a superior physique is supposed to be.
