Arms & delts overpowered his back
it's like comparing apples with bags of smashed assholes...
You would think his arms would overpower everything else in back shots, but he looks good.Shame about that tricep injury.
Having a peanut-sized head like Sergio did also helps with the illusion of overall size.
I got to see Sergio guest pose in 1984. Just a complete freak of nature.
