We now know about more health benefits from physical activity — and how Americans can more easily achieve them. The second edition of the Physical Activity Guidelines for Americans is based on the latest scientific evidence that shows that physical activity has many health benefits independent of other healthy behaviors, like good nutrition.
The recommended amount of physical activity for adults is the same. To attain the most health benefits from physical activity, adults need at least 150 to 300 minutes of moderate-intensity aerobic activity, like brisk walking or fast dancing, each week. Adults also need muscle-strengthening activity, like lifting weights or doing push-ups, at least 2 days each week.
