生命在于运动。但随着社会的大力发展，人们生活水平有了很大的提高。出门多以车代步，家电代替家务劳动。晚饭后常常坐在电视机着看电视，往往看电视连续剧一看就是好多天，这部未等放完另一部好看的又接着放，这样多数人长期缺乏运动，新陈代谢缓慢，脂肪过多地贮于体内，使人过早地发胖，使内脏脂肪充填，负担加大，很快心、肺、肾等主要器官会出现障碍，使你不得不到医院去看医生。大量的时间消耗在医院里，更多的钱花在吃药打针上。运动前要做好体检和心理准备，根据自己的健康状况，制定一个适合自己的运动健身计划，定期总结运动效果，适时调整锻炼方法和运动量。((Life lies in motion.However, with the vigorous development of the society, people's living standards have greatly improved.When we go out, we always take a bus or car instead of walking. And when we do housework, we usually use household appliances instead of working on our own.After dinner, we often sit on the sofa watching TV. We like watching TV series one after another which last for a lot of days. In this way, many people are lack of exercise which may bring about many health problems. For example, the metabolism will become slow and too much fat will be stored in the body, which made people become overweight prematurely. And the fat filled in the internal organs will increase the burden on major organs, such as heart, lung and kidney. At last, you have to see a doctor.A lot of time will be spent in the hospital, and more money will be spent on medicine and injection.Before doing exercise, you should take a physical examination and make psychological preparation. According to your own health condition, you should develop a suitable sports fitness program, regularly summarize the effect of exercise and timely adjust the exercise methods and amount.)
