People are busy working every day, so they don’t have enough time to do exercises. As a result, many people become too fat. To keep our bodies healthy, we have to do exercises every day.

These 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 sometimes called warm-up exercise. Running is also a good exercise. If we can not run fast, we can jog. Jogging means running slowly. Again, before we run or jog, we must do warm-up exercises. Also, we should not run or jog in busy streets. The air is often dirty. Some people like weightlifting (举重) because it can make their bodies strong, we also need to do some warm-up exercises before weightlifting.
