Activity Guidelines

"These studies have also prompted questions as to what type and how much physical activity is needed for various health benefits. That led to the development of The Physical Activity Guidelines for Americans, which gives guidance on the amount of physical activity that will provide health benefits for all Americans. Although some health benefits seem to begin with as little as 60 minutes, or 1 hour, a week, research shows that a total amount of 150 minutes, or 2 hours and 30 minutes, a week of moderate-intensity aerobic activity, such as brisk walking, consistently reduces the risk of many chronic diseases and other adverse health outcomes. For important health benefits, adults need at least 2 hours and 30 minutes, or 150 minutes, of moderate aerobic activity every week, such as brisk walking, and muscle-strengthening activities on 2 or more days a week that work all major muscle groups. They may instead complete 1 hour and 15 minutes, or 75 minutes, of vigorous-intensity aerobic activity, such as jogging or running, every week, or an equivalent mix of moderate- and vigorous-intensity aerobic activity."
