Stretching can discharge lactic acid accumulation, and there will be some lactic acid accumulation in muscles after fitness, especially for people who have not exercised for a long time. Muscle ability decreases, and muscle aches the next day after training, partly because of delayed soreness, and another reason is lactic acid accumulation. Proper stretching after training can accelerate the discharge of lactic acid.
Third, stretching can improve the strain point of muscles. People who train regularly are not prone to muscle fatigue, especially when doing strength training.

Beginners may be tired after doing several groups, while people who train regularly can completely consume the target muscles and stimulate them better.
Fourth, stretching can reduce muscle adhesion, and muscle adhesion will occur after fitness, especially for people who only do strength training during fitness. If you don't stretch, you can train large muscles for a long time, but the muscle shape will not look good.
