In the following time, Wu Li took a group of coaches to practice Xingyi Quan for 8 hours a day from 8 a.m. to 12 p.m. and from 2 p.m. to 6 p.m. every day.

Because these people already have physical fitness and good physical fitness, they learn much faster than ordinary people, Wu Li only needs to teach them the skills of exerting force, and the rest is practiced by themselves.

However, Rao is like this, Wu Li is also tired, and he has to keep talking, correcting them one by one, and repeating the force.

Ordinary people will feel tired when they throw a few punches at the air, not to mention that Wu Li's muscle strength and muscle strength are in unison, every punch has to be in place, and the physical consumption is huge, fortunately, there is a passive skill of endurance muscle to reduce consumption, otherwise it may not be able to last all day.

Wu Li also couldn't rest when he got home at night, and he had to broadcast live and spend time sorting out the advanced tutorials of Xingyiquan, which can be said to be very fulfilling.

By the eighth day, Wu Li's introductory Xingyi boxing tutorial had been fully taught, and an assessment was needed.

All kinds of equipment and dynamometers have been prepared, and Wu Li asked the coaches to come forward one by one to be assessed.

A group of coaches gathered in a circle, their expressions were a little nervous, because Wu Li's ugly words were ahead, and if they failed the assessment, half of this month's business trip allowance would be deducted!

Liu Yuanbo was generous, and the business trip allowance calculated for these people was 600 a day, and if half of it was deducted, it would be more than a month's salary, so everyone was inevitably nervous.

In fact, there are a total of 8 hours of courses, and Wu Li gave everyone 60 hours to master, which is very generous, because after all, these people present have all practiced fighting, have physical fitness, and know how to exert strength, and their learning speed is far beyond that of ordinary people.

Bang! A coach threw a tiger-shaped split punch in front of Wu Li, and slammed one palm on the dynamometer below.

119, which is the number displayed on the force tester, represents 119 kilograms.

Wu Li nodded, signaling that the other party's punch had passed and he could continue to punch the next one.

Its kilogram to represent the punch strength is not correct, because one is the weight, the other is the force, if you really want to describe it, you should use the unit of kinetic energy joule to represent the weight of a punch, but most people are used to the kilogram to represent, feel that this is more intuitive, so many force measuring instruments have also been converted, directly display the weight, although not accurate, but can be used as a reference value.

Most of the boxing game machines on the street that can fight three punches for a few yuan are not accurate, and often ordinary people can hit hundreds of kilograms of strength, but in fact, the heavy punch power of top heavyweight professional boxers can reach about 200~300 kilograms.

Generally speaking, weight is directly proportional to the strength of the punch, and the weight class of a professional heavyweight boxer is above 91 kilograms, and the punch power can reach almost 2 or even 3 times his own weight, which must be achieved after a long period of hard training.

And ordinary people without any training foundation can play a punch equivalent to their own body weight, even if they are qualified, it is quite good to reach the level of 1.2 times their body weight, and it is almost a professional level to reach 1.5 times, although these data do not seem to be exaggerated, but for ordinary people who have not received professional training, if they are hit by a head-on impact equivalent to more than twice their own body weight, it is actually difficult to parry.

Internal boxing to use both muscle and muscle strength, so it is easier than professional boxers to hit a heavy punch higher than their own weight, Wu Li now if he adjusts his posture and then exerts force, he can almost hit a heavy punch equivalent to 3.5 times his own weight, that is, 255 kilograms, comparable to some heavyweight boxing champions!

For these new coaches, Wu Li did not ask too much, but only asked them to use the power posture of Xingyi Quan to play a force equivalent to 1.5 times their own body weight.

Bang! Bang!

One by one, the coaches have come forward to be assessed, and so far no one has failed to pass.

1.5 times the strength is easy to achieve if they are allowed to fight according to their previous posture, even if it is limited now, but as long as they practice it seriously, it is not difficult.

"Xu Chuan. "Wu idea to a name.

A relatively young-looking man stepped forward, saluted Wu Li, and then aimed at the dynamometer in front of him and struck a tiger-shaped fist.

Bang!

146 kg!

"Huo!" the coaches present let out exclamations.

Xu Chuan's weight is 70 kilograms, which means that his target value is only 105 kilograms, and he scored 146 kilograms, which is more than double his own weight, which is by far the highest priority.

Wu Li nodded to Xu Chuan and motioned for him to continue.

Drill boxing, cannon boxing, horizontal boxing, collapse boxing, Xu Chuan used twelve-shaped moves to punch the five elements of Xingyi one by one, almost all of which were stable at about 140 kilograms.

Wu Li nodded secretly, it was obvious that this Xu Chuan had preliminarily mastered the skills of muscles and bones.

In fact, in the process of teaching boxing, Wu Li had already noticed this Xu Chuan, the other party was sent to the martial arts school since he was a child, mainly practicing sanda, originally wanted to be a professional boxer, but later because of an accident at home, he couldn't afford his tuition, so he could only come out of the martial arts school, while working as a coach in the boxing gym, while signing up for some competitions with bonuses.

Xu Chuan is twenty-four years old this year, is at the peak of physical fitness, these few days of contact, Wu Li found that he has a high talent for learning boxing, almost any content is a learning ability, a lecture can be understood, and the same as the previous Wu Li.

This made Wu Li move the mind of accepting apprentices, although when teaching these coaches, he did not hide his selfishness, he taught what he had, and he would point out anything wrong, but a person's energy is limited after all, even if Wu Li does not hide his selfishness, he can only accept a few apprentices at most to teach carefully, and the rest of the people he can't stay by his side at all times to guide, but martial arts is such a thing, with the guidance of the master and without the guidance of the master are completely different things.

Just like teaching boxing this time, Liu Yuanbo is also practicing with him, Wu Li will inevitably give him more guidance, even after class, Liu Yuanbo has questions, Wu Li will answer them as soon as possible, so Liu Yuanbo's progress is faster than most of the coaches present.

It's a pity that Liu Yuanbo's talent is average, and he is a top rich second generation, so he can support Wu Li in business in the future, but he definitely doesn't have to expect him to become a master and help Wu Li support the scene in the future.

And Xu Chuan is different, with Xu Chuan's talent, Wu Li is confident that under his own teaching, the other party will become a master who can take charge in the future.

Although Xu Chuan's age is four years older than Wu Li, when Wu Li is too old to fight in the future, Xu Chuan may not be able to fight, but the apprentice does not necessarily have to wait until he can't fight before it comes to use, for example, when Wu Li is injured, someone comes to the door to challenge, or some unknown people but can disgust people come to challenge, Wu Li doesn't need to do anything with the other party, he can send an apprentice to solve it.

In short, the road that Wu Li will take in the future is destined to be bumpy, and it is better to accept apprentices as soon as possible, and prepare early.

Now that he finally met a person with good qualifications, Wu Li didn't want to miss it easily, he planned to propose this idea to Xu Chuan when the time was right, but he didn't know if the other party was willing.

In about an hour, all the coaches passed the assessment.

"Congratulations to all of you, you have passed the introductory exam, and now you are all qualified to be the coach of the introductory class. Wu Li got up and said to everyone.

"But I'll give you a month in the next month, and we'll continue to learn the advanced content of Xingyi Boxing. The advanced content focuses more on battles and the use of various moves in the ring, which is more difficult, so let's keep working hard. ”

Wu Li's voice fell, and some coaches had already lamented, it was really too hard to practice for 8 days, 8 hours a day, almost no rest time in the middle, and after the end, in order not to be deducted money, many people would practice by themselves, which was harder than many professional athletes.

"Sir Wu, what is this muscle and bone strength that you have been emphasizing, it's too difficult to do. A female coach said with a bitter face.

Because in the process of practicing boxing, Wu Li was very serious and very demanding, which made everyone under a lot of pressure, and once a female coach played a lot of punches in a row and failed to meet Wu Li's requirements, so she complained: "Isn't it, sir, this can't work?"

Including Wu Li, everyone present laughed at the time, so since then, everyone loves to call Wu Li Wu sir.

Wu Li smiled and explained: "Everyone knows that the more relaxed the muscles, the faster the punch can be hit, and the tight muscles can't hit the fast punch, this is the principle of muscle force, first relax, and then instantly tighten." ”

In the same way, we usually practice pile gong in order to stretch the muscles and bones to make them in a state of stretching, and when we exert force, the muscles and bones will also contract instantly, so as to send out stronger force, which is the principle of muscle and bone force. ”

"Everyone thinks that musculoskeletal strength is difficult to master, but in fact, each of us can already use musculoskeletal strength when we are just born. ”

Everyone looked at each other, thinking that Wu Li was joking.

Wu Li smiled: "The baby's body is very soft, and the newborn baby can't control the muscles to contract, but he can still move, and his hands are strong, and at this time he uses muscle and bone strength." ”

It's just that this innate instinct is forgotten as we grow up, and the so-called return to the innate saying of Neijiaquan actually refers to making people return to the state when they were just born, and they can use their muscles and bones freely. ”

"It turns out that this is called returning to innocence. Someone muttered.

Wu Li nodded, I have to say that our ancestors are too talented in naming things, all kinds of names sound like thieves have temperament, what yin and yang are combined, practice the way of emptiness, and return to the innate ...... When you hear it, it feels lofty and difficult to understand.

But in fact, as long as these things are said, combined with reality, martial arts is not a fantasy thing, on the contrary, it is still very close to life.

Next, in addition to continuing to teach a group of coaches, Wu Li plans to start using master-level experience cards to help him break through and return to innocence in the true sense.

The so-called return to innate is to be able to control one's own muscles and bones freely, and its corresponding realm is master!
