Arnold Schwarzenegger

Mr. Olympia
Schwarzenegger's goal was to become the greatest bodybuilder in the world, which meant becoming Mr. Olympia. His first attempt was in 1969, when he lost to three-time champion Sergio Oliva. However, Schwarzenegger came back in 1970 and won the competition, making him the youngest ever Mr. Olympia at the age 23, a record he holds to this day.
He continued his winning streak in the 1971–1974 competitions. In 1975, Schwarzenegger was once again in top form, and won the title for the sixth consecutive time, beating Franco Columbu. After the 1975 Mr. Olympia contest, Schwarzenegger announced his retirement from pressional bodybuilding.
