Second, practice the whole body every day. This idea is absolutely wrong. Absolutely not desirable. Because if you do that, the point won't be prominent. Yes, you have practiced every part of your body, but that's just like practicing in vain, because your physical strength and energy only allow you to practice a certain part of your body in a limited time of 1 hour, and it is impossible to practice your whole body well.
So the correct way should be to practice only a part every day. However, it should be noted here. For example, practice your chest muscles today, but don't practice your chest muscles tomorrow, because muscles need time to recover. If you practice today and tomorrow, your muscles have not fully recovered, which is not only bad for long muscles, but also easy to get hurt.
Thirdly, it is completely correct to practice 1 hour in the gym every day, because after 40 minutes of anaerobic training, some important endocrine hormones that affect training will be greatly reduced until they basically stop, leading to muscle loss. For junior trainers, shortening time and improving efficiency are the habits that must be formed.
