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

There are many kinds of exercise. Bending (弯腰) and stretching (伸展) help us move easily. Before we play ball games or swim, it is better for us to do bending and stretching first. This kind of exercise is sometimes called “warm-up exercise”. Running is also good exercise. If we cannot run fast, we can jog. Jogging means running slowly. Before we run or jog, we must do warm-up exercises. And we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting (举重) because it can make their bodies strong. We also need to do some warm-up exercises before weight lifting.
