Physical activity is one of the best things people can do to improve their health. The U.S. Department of Health and Human Services recommends in the Physical Activity Guidelines for Americans that people of all ages and abilities engage in regular physical activity. This spring, the Community Preventive Services Task Force (CPSTF) issued a recommendation for park, trail, and greenway infrastructure interventions used in combination with additional interventions, such as structured programs or community awareness, to increase physical activity.
