All of that is from Pumping Iron.
Still, that shit gave me a hard-on (NO HOMO).
I will say though, that by todays standards, Arnold was lifting pretty light, at least what was shown in those clips. I toss around the same or more weight. And compared to the brutes of today, he'd get burried.
They trained much higher volume back then, and did it for HOURS a day. Today they would classify that as over training.
I'd hate (LOVE) to see a prime Arnie running the circuits today with the advances in gear, training and nutrition.
