The Fittest of the Fit Index rankings will be updated on a monthly basis throughout the year based on the self-reported runs, bike rides, walks, gym sessions and other calorie-burning activities recorded by the millions of active MapMyFITNESS community members. Anyone who joins the MapMyFITNESS, MapMyRUN, MapMyRIDE or other MapMy community in 2012 and logs their workouts will be able to impact their city and state's rankings.
