Schwarzenegger began weight training at the age of 15. He won the Mr. Universe title at age 20 and went on to win the Mr. Olympia contest seven times. Schwarzenegger has remained a prominent presence in bodybuilding and has written many books and articles on the sport. Schwarzenegger gained worldwide fame as a Hollywood action film icon. He was nicknamed the "Austrian Oak" and the "Styrian Oak" in his bodybuilding days, "Arnie" during his acting career and more recently "The Governator" (a portmanteau of "Governor" and "The Terminator" – one of his best-known movie roles).
