Sergio Oliva & Arnold Schwarzenegger ///
In 1967, Sergio Oliva came into the contest big and ripped and ended up winning the third Mr. Olympia contest. He trained hard after his first Olympia title and looked so much better than the year before, that he won the 1968 Mr. Olympia easily.
The 1969 Mr. Olympia began the greatest rivalry in the history of bodybuilding. A young Austrian named Arnold Schwarzenegger came into the bodybuilding scene and challenged Oliva for the title. The two battled back and forth with Sergio coming out on top. Oliva had collected his third Mr. Olympia title in a row.
Both Arnold and Sergio hit the gym hard for the following year and in 1970, Arnold edged out Sergio to become the third bodybuilder to hold the Mr. Olympia title.
Arnold won The Olympia again in 1971. This was the first year the show was held outside of New York. The contest was held in Paris, which happened to be the same day the NABBA Universe was being held. Arnold competed in the Mr. Olympia while others decided to avoid Arnold and compete in the NABBA competition.
