He was not just a bodybuilder, no one in the body-building scene today has anything in common with him. read his autobiography and listen to all the accounts of people who knew him when he was young, he had crazy ambition and an extra-ordinarily strong will. He used to train with weights after going through arduous military drills throughout the day, and he actually won many competitions like that.
You don't just travel out of post world war 2 Austria, and become the most aesthetic bodybuilder in the history of the world ,graduate from Princeton ,then become the biggest action star ,and governor of California by being lucky.
