"Nineteen...twenty...haha...ha."

Bang!

Takuma Chiba, who had just finished sitting ups, lay on the ground without any image. The upper part of her clothes was completely wet, and even the ground was soaked with sweat.

"No wonder I couldn't hold on. I can only experience this kind of fatigue after doing it. Now I feel that my body is no longer my own." Chiba Takuma said weakly, his body trembling slightly.

If there were only twenty sit-ups, it would definitely not be like this. People in this world are still very strong in physical fitness. Twenty sit-ups are nothing to Takuma Chiba. The reason why Takuma Chiba is so tired is because he exercises strictly according to Teacher Chen's method.

In Chiba Takuma's opinion, Teacher Chen's exercise method has three obvious characteristics.

First, mixing various training contents together, which is a bit like the exercise that claimed to be the most weight-lossing exercise in the previous life - Poppy jumping, mixing some regular training contents such as frog jumping, push-ups, sit-ups, and jumping in the spot. After a complete set of training, you can fully exercise every part of the body, and at the same time you will not cause deformities due to excessive training of a certain part. It is precisely because of this that Chiba Takuma can do such high-intensity training now.

The second is to pursue the limit. In Takuma Chiba’s memory, Teacher Chen once mentioned to himself that his training method is also called "extreme flow", as the name suggests, is to make the body pursue the limit during training.

What is "extreme"? Teacher Chen's definition is quite rough and simple. It means that you need to practice until your body loses feelings and cannot even feel soreness. Extreme flow is a test for both the spirit and the body.

The third is the chakra cooperation method mentioned earlier. Chiba Takuma requires active control and storage of chakra in his body. Using Professor Chen’s special method, he uses chakra at a fixed time to relieve physical fatigue. In addition, he cannot consume all chakra during exercise. He must leave at least 20% of chakra.

Only after the exercise can you call the remaining chakra to recover from fatigue. Of course, this is also a unique skill taught by Teacher Chen, but do you think this will end?

Of course not.

The so-called "Kung Fu is extracurricular". If you want to become stronger, you must not only be strict during extreme training, but also not relax during rest. You must even be stricter. The requirements after exercise are higher. Chakra is needed to repair physical damage and stimulate potential.

If you blindly pursue the limit, you will definitely leave more or less hidden injuries. If you do not deal with these hidden injuries properly, it will inevitably cause irreversible damage.

Here I have to sigh again about the magic of chakra. If a six-year-old child was in his previous life, his body would definitely not be able to stand it after exercising like this. Even adults should cooperate with medicine, so that there is a saying of "rich martial arts and poor literature". However, in this world, there is chakra, and chakra plays a magical role that can restore the body.

Of course, the recovery process cannot be achieved overnight. Depending on the physical fitness, the recovery speed also varies. Some people may take ten days and half a month, while others only need one night. If it is a rich family, they can also use medicinal materials to assist in recovery and enhance physical potential. This is also the reason why there will be a gap between ninjas and civilian ninjas.

Takuma Chiba has some advantages in this regard, because Takuma Chiba’s father works in the Konoha slaughterhouse and has employee benefits. Although it is not a good meat, Takuma Chiba doesn’t have to worry about food energy intake.

Teacher Chen's unique method can make chakra better repair the body. According to Takuma Chiba's estimate, it will take about a week to completely recover. Only after the body is fully recovered can you carry out the next extreme practice. You also need to do moderate exercise during this period.

In short, it is not easy to operate.

"Huh, I'm not at the limit yet, let's have another set." As he said that, Takuma Chiba turned over, supported his body with both hands, and continued to exercise. When his body felt the heat, it was already considered to have reached a limit, but that was not the limit of "extreme current". With willpower, he could actually hold on. A person's will is much stronger than he imagined.

Takuma Chiba estimated that this might be the reason why he had 20% of the chakra left. If there was chakra in his body, it would make his body feel that he was not yet reached its limit, so he could continue to hold on.

According to statistics, nearly half of the people who died in the desert in their previous lives were found. When they were discovered, there was actually water in the kettle. Their minds were to endure for a while and then for a while, and in the end they died of thirst.

This also proves from another perspective that the strength of human will. The 20% chakra left behind is like the water in the kettle of a desert traveler, which can drive the body to reach its true limit.

Of course, there is no need to worry about dying of thirst. After all, chakra is different from the water in a kettle. Chakra is a part of the body. After reaching the limit, it will actively protect the body like white blood cells actively fighting the invading virus.

...

"Is this, extreme current, Takuma?"

The scene of Chiba Takuma's training happened to be seen by Chen Qili who passed by the school. Chen Qili is the son of Teacher Chen and Chen E's husband, Konoha Nishin.

"It's really hard."

He could see at a glance that Chiba Taku was really conducting "extreme current" training. When he was a child, he was also asked to do this kind of training, but he couldn't hold on. After he became a ninja and experienced some things, he realized the importance of strength, but his father was unwilling to teach him.

...

Chen's house.

"E." During dinner, Chen Qili suddenly looked up.

"Ah, what's wrong?"

"If you see Takuma these days, please don't treat him." Chen Qili said.

"Hmm? What's wrong with Takuma? Hasn't his injury been healed?"

"After my mission was over in the afternoon, I passed by the school and happened to see Takuro from outside the fence doing extreme flow exercises."

"That child, he..." As Teacher Chen's wife and a medical ninja, she also knows about "extreme current".

"If you use medical ninjutsu, you should be able to recover better, right?"

"Extreme current is not only pursuing the limit when exercising, but in the next few days, I will feel very uncomfortable, but I still have to continue to exercise moderately. This is a double test of the body and will, and it is also pursuing the limit. I couldn't hold on at the beginning."

"You don't let me treat Takuma, just to see if he can persevere?"

"Um."
