Fitness needs frequency, but how many times you exercise a week depends on your own situation. If your body adapts, I personally suggest that you do some fitness training every day. If you feel very painful and uncomfortable the next day after one day's fitness, then you should rest for two days before training.

The purpose of fitness is to make the body healthier and more powerful. It's not to hurt your health, so you must be careful not to exercise too much. Excessive exercise can cause special pain after fitness, especially when you get up the next day. This is normal, but if you feel pain all over, or even unbearable, this kind of high-intensity fitness is not recommended.

At first, your fitness will make you feel uncomfortable, but after a period of adaptation, you exercise every day, as long as the intensity is not great, and you just feel a little tired the next day, which will not have much impact. If you reach this situation, I recommend you to do high-intensity training one day and low-intensity training one day, which not only has good training effect, but also helps to repair your body. Because the body will be damaged after fitness, you need to rest. The purpose of rest is to wait for the body to recuperate.

Correct training is the key to ensure the fitness effect. If the body is not cultivated in time, continuing high-intensity training can easily cause harm to the body and must be avoided.

Simply put, when you are in poor health, it is enough for you to exercise two or three days a day and two or three times a week. When your body is strong enough to adapt to your training, then you can choose one day's intensity to be higher and the other day's intensity to be lower. This is a leisure sport, and training every day is the most suitable.

For that kind of low-intensity training, just run or something, and high-intensity training must be high, otherwise the training effect will not be achieved.
