I think Arnold has a few body parts that would stand up and more than hold it's own on the Olympia stage like his calves, biceps, and chest. But I think it was his chest that just blew everybody away. Even just barely out of his teens his pecs were already world class and beat everyone else at the time. And they got even better later in his career.
Cant decide between chest,bis or calves.
C’mon! Everyone knows his calves were implants.
Not true.
Chest but Howard Stern was obsessed with his penis during a 90's interview.
His tongue (seriously)His gift of gab and other things, helped propel his career just as much as his physique.
