HOW MUCH EXERCISE IS ENOUGH?

To gain the important health benefits, adults need at least 150 minutes of moderate-intensity aerobic activity (e.g brisk walking), or 75 minutes of vigorous-intensity (e.g running) activity every week.

Activity is best when spread throughout the week, and it can be done is small chunks of time.
