On the second or third day after exercise, many people will feel sore muscles all over. This kind of muscle soreness, which usually appears 24 hours after exercise, is called "delayed muscle soreness" in sports medicine. The pain peaked 24-72 hours after exercise and basically disappeared after 5-7 days.

This is a normal phenomenon. If you don't exercise for a long time and suddenly increase the intensity of exercise, your muscles will feel sore and swollen. You can rest for two days, relax and then exercise, and then your symptoms will basically disappear. It doesn't matter if you keep practicing with pain, as long as you can hold back the pain.
