Question

Exercise is a way of keeping the body healthy through being active. Another name for exercise is physical fitness. Most people exercise in their spare time. Sports are some of the most popular ways to get exercise.

The two main kinds of exercise are aerobic exercise(有氧运动)and anaerobic exercise (无氧运动).Sports such as football and basketball are great forms of exercise 1.

Aerobic exercise is energetic movement that lasts for a certain period of time. 2.The lungs and the heart work harder to bring in extra oxygen. Swimming, cycling, running and rapid walking are good examples of aerobic exercise.

Anaerobic exercise is a powerful burst of movement followed by a period of rest. During anaerobic exercise the muscles need more energy than the body can make with its supply of oxygen. After the exercise a person feels out of breath because the muscles have worked without oxygen. 3.

Exercise affects every part of the body in positive ways. It improves balance and coordination (协调). 4.Exercise strengthens the heart and increases the lungs′ ability to take in oxygen. Through exercise the bones and muscles get stronger, and the whole body becomes healthy and strong.
