You must be caused by excessive exercise. If you are really sore, I suggest you take a few days off and don't exercise. In addition, it is not advisable to exercise in the gym for too long and with too much intensity, otherwise it will damage our health. Some time ago, I saw a news on the internet: "The failure of exercise to lose weight leads to muscle dissolution", which is quite scary and posted on the Luohe River. Finally, urine turned into soy sauce. Exercise to lose weight should be moderate.
