More than 100-Million Americans are walking for exercise, according to a new study from the Centers for Disease Control and Prevention.
In 2010, More than 60 percent of adults said they walked at least once for ten minutes or more in the previous week. That's up from 56 percent in 2005.
The biggest increase in walking for exercise was seen among people living in the south. People who lived in the Western United States walked the most.
Despite this improvement, experts say less than half of Americans are getting enough exercise to improve their health.
CDC officials are encouraging state and local governments, and employers, to promote walking by providing easy access to jogging paths or local gyms.
