Arnold Schwarzenegger doesn't need a membership to surprise Gold's Gym members for a good cause. The actor/ former California governor took on a new role as an undercover fitness instructor and hit up Gold's Gym in Venice, Calif. to prank those working out to raise money and awareness for the After-School All-Stars, a nationwide program that provides free academic support and fun-filled activities to students from low-income families.
If you forward $10 to the organization through omaze.com, you're given the chance to win two tickets to L.A., to ride along with Arnie in his personal Sherman Tank and smoke cigars. Pretty boss stuff right there.
After gluing on a 'stache and slipping on some long threads and a fitted cap, the Terminator star motivated unsuspecting gym rats in the best prank ever. Roll the funny above.
