Showtime bought a new drama series about a no-frills gym in 1970's Venice Beach, Calif., which will star Arnold Schwarzenegger in a recurring role,The Washington Post reported Wednesday. The project, titled Pump, traces the origin of the present-day fitness industry and culture of body worship to a single 1,000-square-foot concrete room on Pacific Avenue, a gym called Pump. Schwarzenegger was brought in to the project after the original creator brought the idea to Two and a Half Men executive producers Eric and Kim Tannenbaum, who invited the former bodybuilder and California governor to join the series.
