The 56th Mr. Olympia will be staged this weekend in Orlando. In celebration, we look back at the history of Olympia programs. You can see not only how the programs have changed (we’re fond of those late-’70s silkscreen Arnold covers) but also how the O evolved: from a small men’s contest in a crowded lineup of shows (always in New York City) in the ’60s to a prestigious, stand-alone men’s contest (held annually in different locations around the globe) in the ’80s and ’90s to a fitness celebration with multiple male and female contests in multiple divisions (in Las Vegas) this century.
