How much physical exercise should a person do every week in order to stay healthy?

30 mins daily of moderate or vigorous exercise.

You should aim to get at least 30 minutes of moderate to vigorous exercise every day, with a minimum goal of exercising 5 days each week. Getting an appropriate amount of daily exercise is a vital part of leading a healthy lifestyle. Daily exercise can help prevent obesity, diabetes, and heart disease, which is one of the leading killers of people in developed countries.

But that exercise doesn’t have to be a trip to the gym. Daily exercise can take many forms, including mowing your lawn, walking your dog, playing a game of basketball with friends, or going on a bike ride with your family. Whatever activity gets you moving and raises your heart rate, it is considered a viable aerobic exercise and counts towards your total daily recommended minutes.
