Arnold Schwarzenegger is going back to his bodybuilding roots.
The action movie star turned politician will become group executive editor for the magazines Flex, and Muscle & Fitness, writing monthly columns in the publications and their online websites, American Media said on Friday.
The "Terminator" star, who began his Hollywood career as a bodybuilder and went on to win five Mr. Universe titles, held the same position at the magazines before he was elected California governor in 2003.
"Bodybuilding has always been part of my life, and I know Muscle & Fitness and Flex will continue to motivate others - as it did me - to lift weights and lead a healthy lifestyle (and) promote the sport of bodybuilding," Schwarzenegger said in a statement.
Schwarzenegger's relationship with the two magazines goes back to 1968, when he was just 21, and he has appeared on their covers more than 60 times.
Schwarzenegger, 65, has taken a diverse path since stepping down as California governor in January 2011, returning to movies in films like "The Last Stand" and "The Expendables 2," writing an autobiography, and launching an eponymous global policy think tank at the University of Southern California's Los Angeles campus.
Muscle & Fitness and Flex are part of American Media Inc , whose other titles include the National Enquirer tabloid, and celebrity magazine OK!
