Exercise would be a doubly efficient venture if people could split into two halves and have both body sections burn calories simultaneously by riding a tandem bike. Today's Groupon makes the most of feasible workouts and fitness activities: for $20, you get a one-month family membership, choice of two personal-training sessions or two private tennis lessons, and a $25 credit toward programs of your choice at the YMCA of Metropolitan Washington (up to a $305 total value). Choose to redeem your membership sessions at the National Capital, Alexandria, Arlington, Reston, Bethesda, Potomac Overlook, or Silver Spring locations.

The YMCA of Metropolitan Washington has been serving families and family-free individuals for more than 150 years. Today's deal gives you one month of family membership (good for two adults and any children under the age of 21 residing in the same household, normally $130) to this venerated institution and its numerous locations, which have numerous amenities. In addition to accessing fitness equipment and indoor and outdoor pools (pool availability varies by location), you'll have a standing invitation to the family festivals and pool events happening throughout the summer. You also get the choice of two personal-training sessions ($120–$140 value) with a certified trainer to help jumpstart a stymied fitness routine or improve a preexisting one. Personal training can even incorporate popular elements such as Zumba, cycling, belly dance, kickboxing, playing catch with computer monitors, and more. If you prefer squeaky-shoe sports, you may also choose two private tennis lessons ($150 value), available at the Bethesda/Chevy Chase location, Silver Spring location, or the YMCA Arlington Tennis and Squash Center.

The $25 credit can be used toward the cost of the YMCA's numerous adult and children's programs, such as one of the many summer camp programs YMCA offers. The credit can also go toward mind and body wellness classes such as yoga, Pilates, and meditation to improve soul and soul sack alike. Program availability varies by location, and $25 will likely not cover the entire cost. Whatever your fitness needs, this membership to the YMCA will help you close in on them. If you like having excuses, you might prefer Nevertime Fitness, which only opens its single Barrow, Alaska, location during solar eclipses.

Today's Groupon expires on August 31st, so you must activate your membership by the end of July to take full advantage of the one-month deal. Current members can redeem this deal for credit toward new program purchases only.
