The Fittest US City Is...

The fittest city in the US also happens to be the capital. So says this year's American Fitness Index, the work of the American College of Sports Medicine. The report scores cities based on a range of factors, including chronic health problems like diabetes; healthy and not-so-healthy behaviors, like diet and smoking; local recreational spots, like playgrounds; use of public transportation; and amount of parkland, USA Today reports. Washington, DC, comes out on top after three years of victory for Minneapolis-St. Paul, which this year comes in second. The rest of the top five:

3. Portland, Oregon
4. Denver
5. San Francisco

And the bottom five of the country's 50 biggest cities:

46. Nashville
47. Indianapolis
48. Oklahoma City
49. Louisville
50. Memphis
