Let's talk about the benefits of fitness to our human body. First of all, fitness can improve the function of the heart and lungs, especially aerobic exercise, such as running or swimming, which can improve the contractility of the heart and increase the vital capacity. Secondly, fitness can improve blood lipid metabolism, lower blood lipid level, lower blood sugar level and reduce the occurrence of diabetes. Thirdly, fitness can reduce weight, reduce the proportion of fat in weight, make muscles more developed and improve basal metabolic rate. Finally, fitness may improve the strength of bones, make bones stronger and reduce the occurrence of osteoporosis.
So fitness is really good for our health, so now many people like to choose fitness in their spare time. People who like fitness generally have a long fitness age. If one day he suddenly stops exercising, he will feel uncomfortable all over, mainly because of habit, which is also a hobby. For example, if you tell a person who has smoked for ten years to give up smoking, he will promise you, but on the first day he starts to give up smoking, he is not used to it. There is also a truth, just like in love, if a person likes someone for many years, tell him that there is no hope and let him give up. He was not used to giving up at first.
If a person who has been exercising for a long time suddenly stops exercising one day, he will feel uncomfortable all over because of his habit. Getting used to this kind of thing is not developed in a day, nor is it quit in a day.
