Tonight's episode of the "Secret Millionaire" will feature Anytime Fitness founders Chuck Runyon and Dave Mortensen. The show, which was filmed in August, will feature the pair in Oklahoma City as they visit the city's organizations. The series is expected to be very emotional, as the millionaires go undercover, surviving on just $75 a week. They will visit nonprofit organizations Limbs for Life and the Oklahoma City Wrestling Foundation.


Runyon and Mortensen are co-founders of Anytime Fitness, a national health club chain with 2,000 locations.
Limbs for Life is a non-profit organization that provides financial aid to those who are in need of prosthetic limbs. The organization's director, Pam Timmons, told newsok.com: "You would have been crying too," Timmons said. "It was overwhelming."


Oklahoma City Wrestling Foundation works to take youths off the streets and get them to wrestle, providing positive role models and coaches for the kids.


Runyon and Mortensen met each other at a well-known chain of midwestern gyms, according to ABC. The two traveled throughout the nation and provided consulting services for fitness clubs. They purchased their first club together in 1995. They went on to establish Anytime Fitness in 2002. As one of the fastest-growing fitness club franchises in the world, it boasts nearly 1.5 million members.


The Secret Millionaire airs on ABC at 8 p.m. E.T tonight.
