Excuse 1: My legs hurt - go out and run first 　　After a long run or intense exercise, you feel as if your body has betrayed you. Don't panic, this is a normal phenomenon, the scientific name is "delayed muscle soreness". This is caused by the lactic acid produced in the muscle fibers after the body has exercised at a certain intensity. Yes, it feels bad. Professional advice: if your muscles start to ache after exercise, no matter how tired you are, keep going. But the amount of exercise can be reduced a bit. 25% is a wonderful number, if you ran 10 km today, the distance you should run the next day is 2500 meters. This amount of exercise is enough to activate your muscles' memory for the exercise, but it won't use up too much of your physical energy and your joints won't be overstressed. The time it takes for lactic acid to be eliminated is related to the level of exercise, and professional athletes won't have soreness soon.
