Arnold is pretty ripped now, but back in the day, he was an absolute freak. Arnold first got people’s attention as a bodybuilder, and is one of the winningest competitors in the history of the discipline. It’s a lot of hard work to look that sculpted, but Arnold was genetically gifted to begin with. At this point, he lacked the muscular definition he would later become famous for, but he was absolutely massive. By the age of 20, he owned and ran his own gym in Munich, Germany, and he won the Mr. Universe competition for the first of four times—the youngest competitor to ever do so. Arnold caught the attention of Joe Weider, the publisher of Flex and Muscle & Fitness Magazines. In 1968, Arnold accepted Weider’s invitation to train and work out in the United States. It was a protégé / mentor relationship that endured for decades to come.
