Sergio Oliva (July 4, 1941 – November 12, 2012) was a bodybuilder known as "The Myth". This sobriquet was arguably given to him by bodybuilder/writer Rick Wayne but Oliva himself has doubted this claim. Supposedly Wayne had begun calling Oliva "The Myth" "(because everyone who saw him at the 1967 Montreal World's Fair said he was "Just unbelievable")".

Sergio Oliva is considered by most to be the world's most genetically gifted bodybuilder. He set a whole new standard for competitive bodybuilding; loved by millions, revered by many and feared by some. He was so huge and extremely proportioned that he used to bring chills to his adversaries. This is how he acquired the name of the Myth."
