For ordinary people, if the physical fitness itself is not particularly high, but when you start exercising, don't do too much exercise. For example, you can exercise three or four days a week. Because in the beginning, people always have an adaptation period. If you do high-intensity exercise at once, it is likely to cause some harm to the human body. And if you exercise every other day, you can basically improve your physical fitness, and you don't need to exercise every day.
If you have certain requirements for the body itself, such as how many muscles you must practice in a certain period of time, or vest line. Or athletes want to participate in a certain competition and improve their ability, it is best to train every day.
