Healthy Activity Environment

Building Places that Get People Moving

Our surroundings can have a profound impact on our actions. This is especially so when it comes to physical activity. If a city has few sidewalks, for example, few people will walk places. If there are no safe places to ride bikes, few people will commute by bike to work or school. If there are no gyms nearby, few people will have a safe and comfortable place to exercise.

More bikeways, less urban sprawl, safer parks—there are many strategies communities can use to make active lifestyles the norm. Read recommendations for designing communities that promote daily activity and making activity safe, affordable, and accessible.

In a nation—and, increasingly, world—where people get less and less physical activity, the “built environment”—the actual physical structures that make up the places where we live, eat, work, play, and go to school—is a key component in the fight against obesity. And it deserves a great deal of attention.

An activity-friendly environment is one that offers a variety of safe and affordable ways to be active. Some environmental changes can help people weave activity into their everyday routines, such as promoting active transportation, so people can walk or ride bikes to shops, school, and workplaces; instituting land use practices that discourage pedestrian-unfriendly sprawl; or designing buildings with attractive stairs, bicycle storage rooms, and layouts that encourage people to get up from their desks. These everyday activity approaches hold promise because they don’t require people to add “exercise” to the to-do list. Other changes can promote active “play” for all ages during free time, such as by opening school gyms to community use on evenings and weekends, or improving public safety, so that people feel comfortable being active outdoors. Media campaigns and social marketing can also help change social norms and encourage people to become more active as part of their daily routine and during their free time.

Integral to implementing such strategies are concerted efforts across many disciplines—transportation and city planners, private developers and employers, community groups and educators. Small-scale changes to the built environment can make a difference. Large-scale changes can make a difference. Together over time, they can provide the structure and support needed to make real and robust strides again obesity.

This section of the website summarizes broad recommendations for improving the physical activity environment, based on a review of expert guidance from the Centers for Disease Control and Prevention, the Institute of Medicine, the World Health Organization, and other major governmental, professional, and public health advocacy organizations. While many of the recommendations are aimed at the local level, state and national governments also play an important role. For more detailed guidance on these recommendations and ideas for putting them into practice, explore the source list on each page, as well as the links to useful toolkits and other resources. Keep in mind that these recommendations are based primarily on a review of U.S. expert guidance, unless otherwise indicated; in other countries, different policy approaches may be needed to achieve improvements in the physical activity environment.
