Why did you exercise in the gym for two days in a row this time? At night, you have insomnia, and you rest very late at night, and you are particularly energetic during the day. This has never happened before. You may be too excited. Exercise, if it exceeds 12 at night, it is easy to fall asleep, and the spirit during the day is only temporary, indicating that you may be in a good mood and particularly excited recently, but you should pay attention to rest. It hurts especially after exercise, which means that you often didn't exercise before, but exercise every day in the future. If you exercise for a long time, it won't hurt.
