A new report looked at 48 medium and large US cities and assigned "active living" scores. Boston nabbed the highest score.

San Francisco came in at No. 2 in the study, which looked at factors like walkability, bike-ability, quality of public transit and availability of well-maintained parks.

Chicago was third in the report, part of the Gallup-Healthways State of American Well-Being Series.

New York -- home of the increasingly popular High Line walking path -- came in fourth.

Washington was named the fifth most active US city. Residents of the top five cities have significantly lower rates, on average, of a handful of diseases (from diabetes to high cholesterol to depression) than people living in cities with low scores.
