This kind of pain is because you do anaerobic exercise, which leads to too much lactic acid in cells, and lactic acid can not be metabolized in time, which will produce a feeling of pain. As for whether you can continue to exercise the next day, it depends on your own lactic acid metabolism speed. If you exercise regularly, he will feel sore during exercise, but he metabolizes lactic acid quickly, so this feeling will disappear the next day and you can continue to exercise. If you feel sore the next day, try not to do high-intensity exercise, but jog and warm up to activate your body, which can speed up your body's metabolism of lactic acid.
