Adults in the Washington area, with the exception of those in Prince George’s County, are more active than the average American, according to the Centers for Disease Control and Prevention. Montgomery County is the most active in the area with only 17.7 percent of adults 20 and older reportedly inactive. By comparison, Prince George’s County is the most inactive local county with 25.5 percent of adults guilty of couch-potato syndrome.

The CDC estimated in its new report that 25.4 percent of U.S. adults failed to spend any free time walking, gardening, golfing, running or other physical activities in 2008. The estimates come from the center’s Behavioral Risk Factor Surveillance System, which is an ongoing, random-digit dialed, adult telephone survey.
