As we all know, keeping healthy is very important for each of us. If we are not strong enough, we will not get good jobs in the future. So, how can we keep fit? In my opinion, we should try our best to do the following:

First of all, I think you'd better exercise every day. People think that people who do exercise every day have healthier hearts than those who don't. However, it is best to exercise regularly. Half an hour a day is enough. It is not a good idea to spend too much or too little time on it. Let's do exercise to keep healthy from now on!

Second, don't eat junk food. It is reported that most children can't help eating junk food every day. This is not a good habit. The reason why we shouldn't eat fast food is that it contains too much fat. The more we eat, the less healthy we are. Eat as many fruits and vegetables as possible, and you will feel better soon!

Thirdly, I suggest that you should try your best to relax yourself. Are you always busy with your homework? Do you often feel tired? Do you have any difficulty in listening to the teacher carefully in class? Why not have a good sleep or listen to wonderful music in your spare time?

In short, there are many ways to stay healthy. If you change your bad habits, you will have a strong body. Have you decided to do as I say? I hope you do!
