Arnold Schwarzenegger

In 1967, Schwarzenegger competed in and won the Munich stone-lifting contest, in which a stone weighing 508 German pounds (254 kg/560 lbs.) is lifted between the legs while standing on two foot rests.
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.
