Advantages: While losing weight, it can also improve cardiopulmonary function and prevent cardiovascular diseases. It is a healthy and effective way to lose weight.

Disadvantages: Not all sports have the effect of losing weight. After strenuous exercise, the blood sugar level will decrease, which will greatly stimulate people's appetite. If you are not careful, the calories you eat will exceed the calories you consume during exercise. Short-term exercise, such as aerobic exercise, lasts only about 1 hour. At this time, the fat has just begun to decompose, but you have stopped exercising, so there is no weight loss effect. There are also rapid and explosive sports, mainly white muscle fibers with thick cross sections. Losing weight like this will only get stronger and stronger.

Even if you reach your ideal weight through proper exercise, it doesn't mean you have lost weight. Once you stop exercising, you will gain weight again. Only by long-term exercise can we keep fit.
