Power starts from the ground, turns to the waist, and then sends it. This is the simplest description of motivation. Internal force is the stunt of China Wushu, the most labor-saving method, and the result of a highly unified and coordinated body. The application of Wushu in the family is the most in place.
The concept of "internal force" comes from the "internal force" in traditional Wushu.
"Strength" is relative to "strength" (main force, driven force). Everyone has "strength" with different strengths and weaknesses, and "strength" needs long-term strict training. There is an image metaphor, "energy" is like the energy when a tiger shakes off the water. So there are "internal strength" and "external strength".
To put it simply, "internal strength" means that the human body exerts its strength on the basis of high coordination, so that this force from the whole body passes through all joints without loss, and then is emitted from a certain point. Those who have not practiced "internal skills" can only attack through "strength" to generalize. Even if a person has strong internal strength, he is vulnerable to "strength".
Bruce Lee once called internal force exercise "flowing energy". This energy (internal force) is produced by the abdomen, not by the shoulders. To do this, it can be assumed that the internal force is "water", which emanates from the abdomen and flows in two arms equivalent to water pipes. In this way, the front end of the arm will become heavy and powerful, and at the same time, the palm of your hand should be stretched and relaxed, and it feels like water is going to be sprayed from your fist. Moreover, the arm seems to be weak, but it is actually very powerful, because it exercises the inner strength of the human body, which is invisible to the eyes.
Internal force, that is, qigong, is real. However, unlike the exaggeration written in the novel, there is no doubt that some qigong can really hurt people. The essence of the' true qi' measured by the instrument is electromagnetic waves, that is, high-energy substances. However, practicing qigong is also very boring. If you are interested, you can Baidu's exercise method.
And explosive power, explosive power, as the name implies, is the power generated instantly. It can be simply understood as the force produced by the rapid contraction of joints and muscles.
Even many people in China don't believe in this kind of thing, mainly because they have never seen it. Of course, qi is invisible. I haven't seen it, but I've experienced it myself. Its existence is also certain. Even Chinese medicine has many theories about qi and blood.
Let's talk about the theory of work first. Each family's internal strength theory is different, which means that each family's internal strength method is different. There are many martial arts schools in China. There are tai chi, octupole, form and meaning, gossip and so on at home. No matter what kind, there is a kind of so-called "gas boxing", and every move must be quiet for a long time. This is the cultivation of internal strength. In jargon, this is called "Gong Zhuang". Junior Gong Zhuang is just to experience Qi. For example, in a certain posture, you should feel the hot air spread from your feet to your waist. If you feel this way, you have practiced correctly, if not, you have practiced wrongly. When you are familiar with the internal force of walking, practice the more advanced Gong Zhuang. At this time, the methods of various factions are involved. How to guide and control one's internal forces, and how to make them run in the body.
The highest state of internal work is called "knowing the body", which means "the body itself knows the movement of Qi". To put it more bluntly, it is called "opening the second pulse of Ren Du". This statement is not unreasonable. People who study Chinese medicine have all studied acupoints, and there is a formula about the sequence and time of qi and blood running in human body. Which viscera to run at noon, which viscera to run at noon ... one day 12 hours so run all over the body. This is a Sunday (congenital big Sunday). This week was born to keep running. It takes an hour for a person who practices internal skills to control the internal forces to run quickly in the body to complete the operation that should be completed in one day. Can he still be like a normal person? And this Sunday (Sunday the day after tomorrow) is divided into two kinds, one is a big Sunday and the other is a small Sunday. Small Sunday means that the control of qi and blood only bypasses Ren Du (starting at Baihui point on the top of the head and ending at Yin Hui point on the crotch). The middle line in front of the body is ren meridian, and the middle line behind it is du meridian), and the long work is fast and slow. Big Sunday refers to controlling qi and blood to bypass all meridians of the whole body, fast and slow. This level of internal cultivation can only be achieved by people who know the body.
People who reach the "body" really give people an unfathomable feeling. There was a famous Taiji master (deceased) who was over 1.6 meters tall. Before his death (when he was over 80 years old), a strong man with a height of 1.9 meters pressed his arm with both hands and pressed him with all his strength. The old man just gave a cry and ejected the strong man more than 2 meters with internal force. This is the power of knowing the body.
In addition, there is also an internal skill that is not used to hit people. Wu Tangmen has a kind of kung fu called "Cold and Summer Iron Cloth Kung Fu", which was founded by Zhang Sanfeng. Practicing this kind of kung fu can make people not afraid of cold and heat, and they can travel around the world in four seasons with only their clothes on. This kind of internal strength involves not only the theory mentioned above, but also the unique world outlook and health preservation theory of Taoism. I won't repeat it here. But again, there is a limit to internal strength. To put it bluntly, internal strength is also a knowledge about the human body. Refuse to go beyond physical limits. In cold and hot weather, it is impossible to explore the Antarctic with only a pair of shorts. The body can't stop the bullet. The internal force can at most make a hole in the iron plate for the aircraft carrier.
