If you practice properly, you will recover excessively when you sleep the next day or the third day, that is to say, if you have pain the next day, if you get better the third day, you will already recover excessively, and you can practice again at noon. If you still have some pain on the third day, it means that your muscles have not recovered and you need to sleep again. I recover the fastest when I sleep, and I certainly won't feel pain on the fourth day, so it is impossible for my muscles to recover for that long. So you can continue practicing on the fourth day-the pain I'm talking about is not the accumulation of lactic acid in the early stage of fitness. If you don't massage and take a bath, it may hurt the whole planet. In fact, your muscles have already recovered-that is, your muscles recovered in about 48 hours, and your excess recovery was between 48 and 72 hours.
