Arnold Schwarzenegger has just released a rap song ... and we're not sure how to feel about it!

Arnold Schwarzenegger can now add rapper to his CV!

The Hollywood legend and former California governor has made the move into music, recording a rap duet titled 'Pump It Up', with Austrian singer Andreas Gabalier.

The song is about motivation and tells the story of Schwarzenegger's career - from a bodybuilder to one of Hollywood's most popular people and the governor of California.

The track details the 71-year-old's life and his drive to always strive for perfection.

"Hey I'm Arnold Schwarzenegger and listen carefully," Schwarzenegger begins. "Dig deep down and ask yourself, who do you want to be. Not what, but who. If you believe success will come to you. Work like hell, trust yourself and all your dreams come true."

The song charts his rise from his early days pumping iron at Venice Beach's Gold's Gym, becoming Mr Universe, attaining movie stardom, and becoming Governor of California, and also includes some of his famous catchphrases like "I'll be back".

"Break some rules, knock the wall, don't be afraid to fail. You have to think outside the box, I say no pain, no gain. I don't want to hear it can't be done, always give something back," he continues, before adding: "My name is Arnold Schwarzenegger and I'll be back."
