The 20 winners that follow have all figured out the right balance between their active citizens and their active leaders. But how exactly did we arrive at this list?

We analyzed 100 of Americas most populous cities and gave each an activity rating based on fitness guidelines, as defined by the Centers for Disease Control and Prevention, and, on the flip side, the percentage of the population reporting inactivity. This rating contributed 50 percent of the weighted score.

Then we looked at general health, with our team determining the percent- age of the population reporting good, very good, or excellent overall health, according to the CDC and various state and county health records. We also pulled self-reported data about heart health and obesity. These three categories made up the other 50 percent of the weighted score, with obesity level carrying 25 percent, general health 15 percent, and cardiac health the remaining 10 percent.

After calculating all that, we found a clear correlation between raw data and fitness culture (how much a city creates opportunities for fitness and encourages connection). A citys culture of activity can play a large role in persuading people to exercise with others, says Dan Giordano, D.P.T., C.S.C.S., cofounder of Bespoke Treatments, a physical-therapy clinic.

These top cities engage people to be activewhether its biking, hiking, or walking, says Michael Fredericson, M.D., of Stanford Medicines Department of Orthopaedic Surgery. Researchers now know that being in shape can involve more than working out in a gym.

It can involve simply stepping outside and joining the community of active people in your city, even ifespecially ifit didnt make this list.
