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 individual (an $83 value) or family membership (good for two adults and any children under the age of 21 residing in the same household, normally $104) to this venerated institution and its numerous locations, which have numerous amenities, including fitness equipment and indoor and outdoor pools (pool availability varies by location). You also get the choice of one personal-training session with a certified trainer to help jump start a stymied fitness routine or improve a preexisting one ($75 value). 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 instead choose one private tennis lesson, available at the Bethesda/Chevy Chase location, Silver Spring location or the YMCA Arlington Tennis and Squash Center ($75 value).
