Anyone who has been to the gym knows that abdominal muscle training is indispensable for reasonable fitness and perfect lines. People who sit in the office all the year round, because of lack of exercise, abdominal fat accumulation, have a great impact on the extrusion of internal organs, so there is no doubt that sit-ups have become a good exercise choice for such people. Some people say that abdominal pain will occur after sit-ups. I want to say that this kind of pain is normal if you just start exercising.

Lactic acid is an intermediate product produced in the process of glucose metabolism during exercise. Because the exercise is relatively excessive and exceeds the intensity of anaerobic exercise, lactic acid produced in the body cannot be further decomposed into water and carbon dioxide in a short time, and anaerobic metabolism is formed due to insufficient oxygen supply, which leads to the accumulation of a large amount of excess lactic acid in the body.

Lactic acid accumulation can cause local muscle soreness. Lactic acid accumulation usually occurs. If you want to accelerate the excretion of lactic acid, one is continuous aerobic exercise to accelerate the excretion of lactic acid by energy metabolism, and the other is fumigation with hot water (such as sauna) or application with hot towel, which can also accelerate the excretion of lactic acid.

Doing relaxation activities for more than 10 minutes after strenuous exercise can keep the cardiovascular system and respiratory system at a high level, which is conducive to paying off the oxygen debt owed during exercise. At the same time, relaxation activities can also relax muscles and avoid affecting the metabolic process due to local circulation disorders. Recommended relaxation activities include jogging, breathing gymnastics and stretching exercises for various muscle groups. Stretching exercise after exercise can eliminate muscle spasm, improve muscle blood circulation, reduce muscle soreness and stiffness, eliminate local fatigue, and also play a good role in preventing sports injuries.

For example, after intense sit-ups, you can do some stretching movements of the waist and abdomen. It can relieve muscle soreness. Generally, after a period of exercise, the body adapts to the intensity of this load, and there will be no muscle soreness caused by lactic acid accumulation.

Because we exercise the abdominal muscles that are not commonly used, we will feel the pain of the muscles, and even feel tears when it is heavier. These are all normal phenomena. Of course, if bad breath is caused by improper methods, you should stop and rest in time, don't drink water, walk slowly, and abdominal pain can also be alleviated. Remember not to eat cold food.
