The best exercise time is around 8 pm. Exercise time should not be too long, just half an hour. If you are strong, take control of it yourself. I don't know the purpose of your exercise. For example, if you are doing fitness, to put it bluntly, it is for muscles. Then you must exhaust the energy of your body, so as to stimulate the potential in your body. Because the body can't bear the load, it will stimulate the growth of muscles. And if you just want to shape, you can't do it. The intensity has to be reduced, usually when you feel tired and sweaty. Then take a bath and go to bed early. Scientific research shows that lack of sleep is also one of the reasons for getting fat. Little Sarah () kindly replied, hoping to help you.
