Question

People are busy working every day， so they do not have enough time to do exercise. As a result， many people become too fat or too thin. To keep our bodies healthy， we have to do exercise every day.

There are many kinds of exercises. Bending (弯腰) and stretching (伸展) helps us move easily. Before we play ball games or swim， it is better for us to do bending and stretching exercises first. This kind of exercise is something called warm-up exercise.
