Based on documented results of the top bodybuilding contest, the title of most muscular man ever is held by a two-way tie between Lee Haney, Mr. Olympia (1984-1991), and Ronnie Coleman, Mr. Olympia (1998-2005), according to the Mr. Olympia website. Opinions of individuals may differ subjectively from judging decisions.
Using the Mr. Olympia contest results as judging criteria gives a fair estimate of the most muscular man ever, since it is the highest honor winnable in bodybuilding. Arnold Schwarzenegger is the second most-winning Mr. Olympia competitor of all time with seven wins. Third place in this category goes to Dorian Yates with six wins.
