Guys know how to get fit in the nation's capital. They skirt traffic jams by biking to work and run circles around the city's miles of monuments, outdoor malls, and parks. And with an off-the-charts number of swimming pools, plus plenty of tennis courts, rec centers, and dog parks throughout the metro, staying active is easy. The residents eat healthy too. D.C. has way more farmers' markets than in most big cities. As a result, they average five or more servings of fruit and veggies a day, which plays a role in the city's low prevalence of heart disease. D.C. residents also have ready access to more top-notch health care facilities and providers than people in most metropolitans do, which never hurts.
