Long-term fitness will make our bodies healthier and get unexpected good results. First of all, people who exercise for a long time live a regular life. They have regular work and rest, good living habits, seldom stay up late, often get up early, seldom smoke and drink, eat healthier food and avoid eating high-calorie food and junk food, so they will get healthier bodies. Secondly, people who exercise for a long time are younger. Research shows that long-term exercise can change the structure of human DNA, and people who exercise for a long time are younger and more energetic than those who don't exercise, thus delaying aging. Third, generally speaking, people tend to get fat in adulthood, especially in middle age. This is because people have great work pressure, more social activities and less dietary constraints, and may not pay attention to their appearance as they did when they were young. People who exercise for a long time, both men and women, will not get fat as easily as their peers. Therefore, long-term exercise can give us a healthy and stylish body. Fourth, people who exercise for a long time generally have great strength. People who exercise regularly will have stronger physical and mental strength than those who don't exercise regularly. Physical exercise can not only improve our physical fitness, for example, lifting heavy objects easily, but also exercise our willpower, cultivate our hard-working spirit and overcome difficulties with perseverance, so generally speaking, people who exercise regularly are more resistant to pressure. Fifth, people who exercise regularly have more flexible minds and become smarter. Physical exercise can accelerate the growth and division of cells in our brain, because the growth and division of cells in our brain will slow down in adulthood. Aerobic exercise we do will also provide oxygen to the brain and promote the regulation of the body's metabolism, so people who exercise for a long time will become smarter.
