As part of his advocacy in promoting health and fitness, action movie icon Arnold Schwarzenegger recently went undercover as an employee at a Gold's Gym.

To raise awareness for After-School All-Stars, national provider of year-round, school-based, comprehensive after-school programs, Arnold made this prank video where he disguised himself as a Gold’s Gym trainor.

Arnold’s message:

I wanted to have a little fun and raise money for a good cause, so I went to Gold’s Gym in Venice in disguise. You can help! Please enter for a chance to ride with me on my tank and do some lifts together. Visit www.omaze.com/Arnold to support and spend an afternoon with me.

Can some gym rats recognize Arnold with his picture on the wall? Watch this video which already garnered almost 3 million hits since January 21, 2014:
