This is caused by the fact that waste and lactic acid in muscle are not rushed out of the body. I don't think you relaxed well after exercise. Let me talk about my usual fitness experience. How can you quickly excrete waste from muscles? In the field of fitness, there is a common method of alternating hot and cold showers, which can quickly relieve muscle soreness, but this method is obviously not suitable for ordinary people in winter. Another common method is doing aerobic exercise. For example, you can find a very light dumbbell, bend it once and lift it 100 times. The principle is: small weight, more times! After running for 30 minutes, the most important thing is to eat more eggs Replenishing protein in an emergency is king!
