One of the world's most famous action movie stars put on a (awfully obvious) disguise and pretended to be an employee at Gold's Gym in Venice Beach, CA. Arnold Schwarzenegger plays Howard Kleiner, a regional manager who takes his business seriously and makes sure that those working out in his gym know the proper techniques of water drinking.

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.
