Exercise is an important part of daily care of the body. Physical exercise helps keep weight under control by using some of the energy supplied by food. Exercise is good for the blood vessels because it helps keep even the smaller blood vessels open. Exercise also keep the muscles healthy and in a good tone. This means that even when they are at the rest not completely limp. Some of the muscle fibres are straightly tensed so that the muscles are always ready to be used.
Healthy muscles have a great deal to do with good posture. When your muscles have a good tone, it is much easier for you to hold your body as it should be held - the head straight, chest up, stomach flat, and lower back curved as little as possible.
Through certain kinds of exercise, such as tennis, badminton, or dancing, many different sets of muscles become trained so that they move together smoothly. This is known as coordination. If you learn coordination, you will find that they are able to use your muscles so that all your movements seem easy and graceful.
You should get at least 15 minutes planned, vigorous exercise every day. This is in addition to exercise you normally get by walking, doing some jobs arround the home and so on.
