Life lies in exercise. However, with the vigorous development of society, people's living standards have been greatly improved. Most people go out by car, and household appliances take the place of housework. After dinner, I often sit in front of the TV and watch TV. I often watch TV series for several days in a row. This one was played before the other one finished. As a result, most people lack exercise for a long time, their metabolism is slow, and they store too much fat in their bodies, which makes them gain weight prematurely and increase their burden. Soon, the heart, lungs, kidneys and other major organs will appear obstacles, making you have to go to the hospital. A lot of time is spent in the hospital, and more money is spent on taking medicine and injections. Physical examination and psychological preparation should be done before exercise. According to your own health, you should make a fitness plan that suits you, summarize the exercise effect regularly, and adjust the exercise method and amount in time.
