Explain two points. First, the exercise time of half an hour before going to bed is too short. If you want to lose weight, you'd better do it for an hour, at least 45 minutes. Because you only warmed up for half an hour, you didn't consume any energy at all. It usually takes half an hour to start consuming. Therefore, people who lose weight generally require one-time exercise 1 hour or more.

Second, lie down after you finish, not for nothing, definitely not, but resting immediately after exercise is not good for sleep, and it will still have an impact on your health for a long time, so it is best to exercise early and then stop for an hour or two before going to sleep.
