A review of 10 studies suggests that creating or enhancing access to places for physical activity, such as fitness centers or trails, combined with informational outreach, such as training on equipment or health education, is effective in increasing physical activity. In the five studies that measured change in aerobic capacity, the median increase was 5.1%. In the two studies that measured change in energy expenditure, the median increase was 8.2%. In the five studies that measured frequency of physical activity, the median increase was 48.4%.
