Explanation:

The combination of aerobic and muscle-strengthening physical activity is crucial for a healthy lifestyle. Regular physical activity can help to reduce the risk of cardiovascular and chronic diseases, disability and premature mortality.  

Adults need a moderate physical aerobic activity for a minimum of 30 minutes 5 days a week or 20 minutes of vigorous-intensity aerobic activity. A combination of these two can be done to achieve this goal.

A moderate-intensity physical activity, like fast walking, should produce a noticeable rise in heart rate and breathing. On the other hand, a vigorous-intensity activity, like running, should produce a large and bigger change in heart rate and breathing.

The muscle-strengthening activity, should be performed for a minimum of 2 days a week on two or more nonconsecutive days.
