Running

Running is good for people with too much fat because it can help them become slim. It also makes people strong. But it may be bad for joints(关节). If we don't feel comfortable in our joints, we should stop for another activity.

Walking

Walking makes our bodies relaxed(放松的). It can also help people to be slim.

Swimming

Swimming is a great way to make different places of your body strong. But it is not a good way to keep slim. The water in a swimming pool is cooler than our body. The body protects(保护)itself from the cold by keeping fat.

Cycling

Riding a bike will help us be slim and make our legs strong, too. But be careful! If you live in the city, you should ride on the bike road and be away from the busy traffic.
