Shortly after taking part in sports, no matter whether you are fat or thin, your weight tends to increase after starting sports. This is because after exercise, the absorption is enhanced, the muscle is increased, and the muscle is heavier than the fat, but the fat has not been consumed for the time being. At the same time, the demand for food after exercise is greater, and sleep will be better. Several factors lead to the weight gain after exercise.

If you persist in exercise, the growth rate of muscles will obviously slow down after they grow from a low level to a certain limit. At this time, exercise began to consume fat, and the real weight loss began at this time.

Fitness is a kind of exercise, such as all kinds of unarmed aerobics, rhythmic gymnastics, rhythmic gymnastics, and all kinds of self-resistance movements. Gymnastics can enhance the strength, flexibility, endurance, coordination and control of all parts of the body, thus making the body strong. If you want to relieve stress, exercise at least three times a week.

Swimming, brisk walking, jogging, cycling and all aerobic exercises can exercise the heart. Aerobic exercise has many benefits: it can exercise the heart and lungs, enhance the function of the circulatory system, burn fat, increase vital capacity, lower blood pressure, and even prevent diabetes and reduce the occurrence of heart disease.

The American College of Sports Medicine suggests that if you want to know whether the intensity of aerobic exercise is appropriate, you can test your heart rate to reach 60%-90% of the highest heart rate after exercise. If you want to lose weight through aerobic exercise, you can choose low to moderate exercise intensity and extend exercise time. This method consumes more calories. Exercise frequency is 3-5 times a week, 20-60 minutes each time.

If you want to exercise your muscles, you can do weight lifting, gymnastics and other exercises that repeatedly stretch and flex your muscles. Muscle exercise can burn calories, enhance bone density, reduce the chance of injury, especially joint injury, and prevent osteoporosis. Before you lift weights, measure them. If you can lift eight times in a row, practice from this weight.

When you can lift this weight 12 times in a row, try to increase the weight by 5%. Pay attention to lifting 8- 12 times in a row every exercise, so as to reach 70%-80% of the maximum endurance of muscles, and the exercise effect is good. 2-3 times a week, but avoid exercising the same group of muscles for two consecutive days to give the muscles sufficient recovery time.
