Fitness is a comprehensive sport, not only a sport, but also closely related to diet, rest and exercise control. There are two reasons why you are tired. First of all, you must not get enough sleep. You know, muscles grow when we are resting. During exercise, your muscles are congested and slightly torn, and during rest, you will grow because of greater recovery. Therefore, sleep is essential. If you do a lot of exercise and sleep less than 8 hours a day, it will be difficult for your muscles to rest and grow, and you will not have the unique pumping feeling of new muscles the next day. Instead, I feel a little numb. Secondly, you said that you go every day, which is wrong. If your training cycle is so tight that you are not influenced by the past every day, it can only show that your strength or motion perception is not in place. I suggest that you divide your body into six muscle groups, with a cycle of three days, so that you can get twice the result with half the effort.
