Humans need physical exercise every day. It can take the form of walking, swimming, running or playing a sport, for example. 

By exercising, you raise your energy levels and maintain your health.

Some people like competitive forms of exercise, such as team sports. However, exercise does not always need to have the element of competition. 

Everyone should get at least 1,5 hours of physical exercise each day. 0,5 hours of this should be demanding physical exercise, which means that it should make you sweat.
