I agree he looks like crap in that photo.
Arnold as a bodybuilder is a strange beast. In some ways, I find his physique amazing, but in others, completely not so.
He also never had the appearance of great strength and power.
I love when idiots suggest Arnie benched 500 pounds. My former boss, Robert Kennedy, was The Oak's friend and witnessed him training many times during his peak years. He said Arnold was nowhere near that kind of poundage on the bench press. More like 315 for sets if eight, when he was strong.
He was also a shit squatter. Check out Pumping Iron. He uses 315 and is doing very shallow reps.
These magazines just keep squeezing the Arnold pics for everything they're worth. When I was at MuscleMag, featuring him on the cover was an immediate guarantee for better sales. It's unreal to imagine that 20 years later this could still be the case.
Everyone's seen every single photo of the guy in his prime. And workout secrets? As another says, the "secret" is called Dianabol. LOTS of it. Kennedy told me he'd literally pour a huge handful into his hand (not bothering to count them) and back it down with a protein shake.
