Muscle Beach refers to the exclusive Santa Monica location of the birthplace of the physical fitness boom in the US during the 20th century, started in 1934 with predominantly gymnastics activities on the south side of the Santa Monica Pier. Muscle Beach Venice is the contemporary title of the outdoor weightlifting platform constructed in Venice, Calif., 18 years after Muscle Beach was established. Muscle Beach Venice was officially titled in 1987 by the City of Los Angeles with the distinguishing name 'Venice' added to the location to honor the original Santa Monica site. The contemporary Muscle Beach Venice is located two blocks north of Venice Boulevard on Ocean Front Walk in Venice, California. Santa Monica's "Muscle Beach" landmark derives its name from the growing local and national reputation of gymnastics and strength athletes who congregated at what was first known simply as the "Santa Monica Beach Playground", with the 'muscle' term gaining momentum by 1940. The 1940 opening of the first of an eventual nationwide chain of weightlifting gyms by famed pioneer gym chain operator, Vic Tanny, only two city blocks from Muscle Beach in Santa Monica is commonly considered a key contributor to the increasing attraction of bodybuilders and strength lifters to Muscle Beach from across the nation. By the 1950s Muscle Beach established worldwide fame and helped to popularize and bring legitimacy to physical culture with acrobatics and bodybuilding.
