Ranked from 1 to 100 1. Seattle, WA the most active. 100. Lexington, KY the least. 70. Houston, TX http://health.msn.com/healthy-living/americas-most-sedentary-cities?page=1 Summer is the season for kicking back and doing nothing, which means it's always summer in Lexington, Kentucky. In fact, folks there didn't need to lift a finger to be named America's Most Sedentary City, since movement of any kind means you're not a committed couch potato. Now, we don't doubt the Lexington work ethic—it's the workout ethic we question. We looked at where and how often people exercise (Experian Marketing Services); the percentage of households that watch more than 15 hours of cable a week and buy more than 11 video games a year (Mediamark Research); and the rate of deaths from deep-vein thrombosis, a condition linked to a lot of sitting (CDC). And since some people define "exercise" loosely, we gave credit for any physical activity in the past month (CDC).
