If you want to exercise your muscles, you should do anaerobic exercise. On the basis of aerobic exercise, you can do it for a few minutes at a time, 2~3 times a week, because the formation and repair of muscles need a process, so that muscles can be fully recovered and rested, so that muscles can be better trained.
If the purpose of exercise is to eliminate excess fat and lose weight, you need to exercise more than 5 times a week. With the increase of exercise frequency, the effect will also increase, because the exercise frequency is directly related to the exercise effect.
After one exercise, the fitness effect on the muscles, organs and piping system of the whole body can be maintained for at least 3 days. That is, do the second exercise before the effect of the previous exercise disappears, so that the effect of each exercise will accumulate and achieve the purpose of improving health.
If the interval between each exercise is too long, it will destroy the continuity of exercise training and it will be difficult to achieve the expected fitness effect. Moreover, it is easy to cause muscle soreness, fatigue and even muscle joint injury after each exercise.

Secondly, people who lose weight can increase the intensity of running according to their own situation to achieve the effect of fitness and weight loss, but if they feel unwell, they should stop in time.

After moderate exercise, the fitness effect on the muscles and organs of the whole body can last for several hours to several days. Therefore, the most suitable exercise frequency should be mastered in the following points: do the second exercise before the effect of the last exercise disappears. In this way, the fitness effect of each exercise will gradually accumulate, achieving the purpose of enhancing physical fitness and improving health. Otherwise, the interval of each exercise is too long, which destroys the continuity of exercise training and makes it difficult to achieve the expected fitness effect. Muscle soreness, fatigue and some sports injuries are also prone to occur after each exercise.
