Physical fitness depends mainly on regular activity and exercise. This can be as simple as a brisk walk several times a week. Or it might be regular visits to the gym, working out at home, playing sports or ball games, swimming, cycling, dance, running… the list is very long.
Activity should be regular, at least five times each week for adults. It should also last at least 30 minutes each time, and involve enough exercise to speed up breathing and heart rate. Young people should do more exercise than this. Some people make exercise part of their daily routine. Others like to set aside time for it, perhaps in a group, for example, playing team games for a club.
FOOD AND DRINK
A car engine soon breaks down if it has dirty water in its tank, rather than proper fuel. The human body also needs proper fuel in the form of healthy foods and drinks. They provide energy for activity, and also nutrients to keep the body working well and to prevent disease. A healthy selection of foods and drinks is called a balanced diet. It includes a wide variety of foods, especially fresh fruits and vegetables. It also means not eating too many fatty foods, especially fatty meats. Too much of certain foods can cause ill health and diseases of the stomach, intestines and other body parts.
