#2 Arnold Schwarzenegger
Starting out as a professional bodybuilder, the 'Terminator' won the Mr. Universe title at the age of 20 and went on to win the Mr. Olympia contest seven times in a row. Later, Arnold led a successful professional career as an actor, director, filmmaker, businessman, philanthropist, author and currently a politician. He has also served two terms as the 38th Governor of California, representing the Republican party.
Years later, Arnold admitted to using steroids in a shocking revelation. He said that drugs were 'new' in those days and were actively recommended by doctors for bodybuilding and faster healing. Rules for drugs were tangible in those days and also less awareness drove almost everyone to consume substances at least in bodybuilding, to remain in the competition.
