Women's Health and Yelp did a pretty extensive study in which they determined 20 of the nation's most social cities and divided their results into four categories. Cities were judged based on their Yelp reviews in fitness, nightlife, culture, and food. Turns out that despite Michigan being one of the fattest states in the union, Ann Arbor happens to be one of the country's most sporty cities.
In their October 2014 issue Women's Health editors briefly discuss why the city topped the list. Referring to residents as "sporty," they mention several of the city's parks such as Gallup, Bird Hills, and the Nichols Arboretum. Check out the issue for more on why Ann Arbor is so fit and sporty.
