Without George Washington’s membership to the YMCA, our first president would’ve never had the fearsome biceps and tenacious determination to destroy the Redcoats' man-eating cherry tree. Prep your body for the next British invasion with today’s Groupon: for $20, you get a one-month household membership plus $50 worth of credit toward any program at YMCA of Greater Tulsa (a $118.25 total value). This deal also waives the normal $54 joining fee, both for your month of membership and if you wish to renew your membership at normal rates. This deal is good at any of the seven YMCA facilities in the greater Tulsa area.

Since 1909, YMCA of Greater Tulsa has helped build strong families and even stronger bicep bulges—keeping families and individuals active with fitness formats that are much more fun than underwater boot camps or being hunted for sport by eccentric millionaires. Firm up your form and increase your energy level with unfettered access to pools, basketball courts, weight gyms, and thumb-wrestling arenas, all included with your membership.

You can use your $50 credit toward a personal trainer, who’ll pave the most efficient path to your own personal peak by designing a specific individual curriculum. Or apply your credit at a choice of program, such as seasonal youth sports, several rejuvenating yoga classes, Pilates, high-energy water aerobics, and self-defense-sharpening martial arts classes. Programs and classes vary by location, so be sure to check in with your specific YMCA to know what activities are available.

At the YMCA, members can impress peers by transforming into modern-day Renaissance men and women, becoming the center of attention during the season's post-demolition-derby dinner parties and hot-air-balloon soirees. Sharpen your free-throwing skills, take a refreshing dip in the pool, or give your body the thorough workout it’s asked for since your five-day C-SPAN marathon with today’s Groupon to the YMCA of Greater Tulsa.

For current YMCA members, today's Groupon may be used toward program registration only.
