Martial arts says, "practice your breath inside and your bones and muscles outside." How to practice these two things?

It is a well-known boxing proverb to "exercise your muscles and bones inside and outside". Although everyone can say it, most people who practice martial arts can't really understand its meaning, let alone show it in the process of practicing martial arts. Here, the author only analyzes this boxing proverb from the viewpoint of one family. The definition of "internal qi" mentioned here is very similar in Chinese medicine and martial arts. In fact, "qi" has two meanings in the human body: one refers to the breathing qi, and the other refers to the internal qi of the human body. In Su Wen of Neijing, it is said that "the innate qi passes through the lungs and the acquired qi passes through the throat", which means that "weather" passes through the lungs from breathing, and "acquired qi" (that is, Shui Gu's qi) enters the pharynx from diet. In Neijing Lingshu, it is also said that "the true qi is influenced by the secret, and it is integrated with the valley qi to fill the whole body", which further proves that "the true qi" is the combination of Shui Gu's qi and breathing qi and has the function of nourishing the whole body. It can be seen that "true qi" is the foundation of human body and the motive force of human life activities. The ancients thought that "essence, qi and spirit" were the three treasures of the human body, so it can be seen that "qi" is a very important substance, especially for regulating and promoting human blood. Traditional Chinese medicine pays attention to "qi is handsome for blood, and qi promotes blood circulation by itself", but the human body cannot live without the circulation and nourishment of blood. Therefore, "Qi" is the foundation of life. The Book of Changes says that "the spirit is invisible and the bones and muscles are tangible", so "those who practice the tangible are invisible, and those who practice the intangible are tangible." The true qi is invisible and intangible, but it exists objectively and is the dependence of life activities. Both spirit and body can be nursed back to health through it. As an intangible thing, the essence can only be adjusted by thinking, and qi can be enhanced by physical exercise, so it is of practical significance to advocate the practice of internal qi in Wushu. Practicing internal qi is one of the necessary kung fu for martial arts practitioners. As early as thousands of years ago, Zhuangzi put forward the theory that "it's only for a long life", and Mencius also said that "it's good to keep my integrity". Therefore, only by practicing internal skills and external skills, keeping shape with luck, keeping shape with qi and combining qi and shape can we achieve the Excellence of Kung Fu. The "internal triad" and "external triad" mentioned in the boxing classics are the specific requirements of practicing internal qi and appearance, and are the combination of internal and external factors. The foot of internal qi can nourish and moisten the human body, and the exercise of external qi can also regulate internal qi to a certain extent. They are complementary and inseparable. The training methods of internal qi and appearance are different, and so are the training methods of internal qi and external boxing. However, the author thinks that there is not much difference between Neijia Boxing and Waijia Boxing in the essence of practicing Qi, but there are slight differences in methods and operation forms. Many methods of practicing Qi in modern boxing are too complicated, which turns the original simple principle into thousands of laws and regulations. What is good luck, good luck in the week, collecting gas, opening gas, and inner alchemy, such as self-restraint, has little effect. Because practicing qi is an invisible sport, it is not excluded that some people who practice martial arts are extraordinary, but there are few breakthroughs in practicing appearance. They basically follow the traditional martial arts training methods and rely entirely on equipment to practice. In fact, in order to prove the significance of Xi's straight boxing, one is to look at the health care effect, and the other is to experience the actual combat effect. If you try, you will find the authenticity of what you have learned about boxing. Practicing internal qi and appearance, focusing on health preservation function and focusing on attack and defense function, the performance is very rich. First of all, the internal force is sufficient and the viscera function is strong, but the internal force actually has high cardiopulmonary function, good human endurance and certain combat ability; Secondly, in appearance, the muscles are thick, the bones are hard, the skin is thick, the muscles are elastic, and they can strike hard and react quickly. So in actual combat, they are not afraid of being pinched, robbed and beaten by each other. Therefore, it can be said that the sentence "practice one breath inside and exercise one's muscles outside" highly summarizes the whole process of Wushu. It is not only a boxing theory of practicing martial arts, but also a combination of philosophy, martial arts, health preservation and other theories. It is a high generalization of traditional martial arts, has a guiding role in thinking and action, and is the ultimate embodiment of martial arts practitioners' skills.
