On the sofa in the living room of the knife factory, the fat tiger and the orange cat were sticky together, they hadn't seen each other for a long time, and found that the little fat man was not attentive, and was actually watching TV, and the orange cat used his paws to dial his ugly face to himself.

Ji An looked at the video on Hu Ai's mobile phone and said suspiciously: "I still haven't seen when they gave the medicine." ”

Hu Ai approached, pointed to the screen and said, "At the very beginning, the medicine was sandwiched in the little finger by Wan Yin......"

Ji An interrupted: "Wan Yin?"

Hu Ai nodded: "He is my former high school classmate." Then he continued: "You see, that day he deliberately ordered the black formula, and after opening the bottle and pouring it, when he picked up the cup, he released his little thumb and the medicine fell in. ”

Ji An took a closer look, vaguely saw something fall into the cup, and said, "It's really, amazing, it's almost time to change magic." ”

The good man's mood came and went quickly, and it had returned to normal, she said: "What's so good about this? If you are the current little brother, you don't need to be drugged, Xiao Ai, right?"

Hu Ai smiled but did not speak, and his small dimples were sunken. Ji An snorted, thinking about going to the street to brush his face another day, and with his current overnight fee of 500 Buddha jumping over the wall, to see if there was a young lady who would scream.

Glancing at the time, Ji An remembered that there was still something to do, and asked, "Hu Ai, there is something I want to ask you." ”

Seeing Hu Ai's gaze turn to him, Ji An organized his wording and said, "For example, I need to swing 60 swords with all my strength in 60 seconds, but I probably don't have the strength after 30 swords now, is there any way to improve this?"

After listening, Hu Ai thought about it, the bright color in his eyes flashed, got up and walked to the wall, pulled out the eight-sided Han sword made by Ren Hu Yidao and handed it to Ji An, and said, "Little brother, you go to the courtyard first and swing the sword with all your strength 30 times, I'll take a look." ”

Ji An took it and walked out of the house into the yard.

The eight-sided Han sword in his hand is more slender than his Zhan Lu, and its beauty is not much inferior to that of Zhan Lu, but it is slightly delicate, and its weight is lighter than that of Zhan Lu, which is more suitable for scholars to wear.

Ji An only tried a few swords, but Hu Ai quickly stopped and said, "There is room for improvement." ”

Returning to the house, closing the door, blocking the cold wind outside, Hu Ai didn't speak, Zhuang Ying rushed and said: "Little brother, you have to pay attention to your breathing." ”

Ji An was puzzled and asked, "What do you mean? What is this about breathing?"

In this regard, a good man can also be regarded as an expert, but it is a little difficult for her to express it, scratching her head for a long time and not knowing what to say, she is so anxious that she is "wow, yes, ......"

Hu Ai still said, she said: "Little brother boxing match, right?"

Ji An nodded, and Hu Ai continued: "Have you paid attention to the 'hiss' sound made by the fighter when he punches?"

Ji An blinked and thought back, "It seems that there is, what is that?" People who have never fought thought that the 'hissing' sound is a fist style, and it is definitely not only Ji An.

Hu Ai smiled: "The aura has not been revived, who is so powerful that he can punch out a hissing fist? That's the sound of breathing." ”

Ji An continued to be stunned: "The sound of breathing?"

Everything is going in the direction expected by a bad girl, the smile on the corner of Hu Ai's mouth disappears, the two white hands clench their fists, and they gesture out of the punch, not to mention, they are quite presentable, she punches, at the same time, a short "hiss" sound squeezed out from between her teeth, explaining: "Keep breathing when punching, or rather, whether punching or sword, don't forget to breathe when you do anything." ”

It sounds like nonsense, but in fact, Hu Ai continued: "Like the little brother just now, it is not right to muster up your strength and swing your sword with all your strength while holding your breath. Although the strength may be a little stronger, on the one hand, it is easy to injure the internal organs, which is what we often say, holding out the small intestine qi, and the exercise term is called hernia.

On the other hand, if you hold your breath and exert all your strength every time you swing your sword, it will not take a few strokes for your body to enter anaerobic respiration, and a large amount of lactic acid will be secreted in your muscles. Professional fighters have longer bursts than ordinary fighters, and the key is to keep breathing while punching.

Just like me and Zhuang Ying, we will shout when we swing the racket with all our might, not to shout momentum, this is a way to assist in breathing. ”

"That's right, that's what I'm trying to say. The good man slapped his leg and interjected.

Hu Ai said: "Little brother, try it yourself." ”

Ji An nodded, compared his posture, and thought for a while: "Punch and keep breathing......"

Ji An just tried it once, and Hu Ai shook his head: "No, don't come out directly in one breath, so that the strength will also be discharged, pay attention to the force in the lower abdomen." ”

"Strength in the lower abdomen?" Ji An was confused.

Hu Ai smiled, and for a moment, like a little fox who had stolen a chicken, she said, "Little brother, you stand up." Well...... Lift up your clothes. ”

Ji An, a big man, is still afraid of being looked at? Dafang lifted his clothes, revealing his belly button, and there were 8 neat chocolates that could make the little fists scream.

"Ouch, I'm ashamed, don't look at it, don't look at it. On the sofa, the good man covered his face shyly. Her face was tightly covered, but between her open fingers, both eyes leaked out.

Hu Ai stepped forward and raised his hand to stroke the "chocolate", Ji An was caught off guard and retreated half a step, and the good man on the sofa exploded, shouting "ashamed to death", while stomping his feet hard with "dong dong dong".

Ji An looked at it and complained in his heart: "Don't look at it if you're ashamed." ”

Hu Ai said seriously: "Little brother, try again, like a ball leaking, when punching, the lower abdomen is tightly closed, and it is squeezed out between the teeth little by little." ”

Ji An did so.

But as soon as the abdominal muscles were forced, the touch became clearer and clearer, and Hu Ai subconsciously teased it with his fingers. Immediately found that Ji An seemed to notice something wrong, she hurriedly turned around and said, "Zhuang Ying, you can also try it and see if it's right." ”

"No, I don't, people still talk about boyfriends. The good man changed to cover his eyes with one hand, stretched out the other, and waved his hand to refuse.

Hu Ai: "What's this? We're teaching my little brother how to breathe. ”

The good man shouted in his mouth not to, Hu Ai grabbed Zhuang Ying's hand and pulled it gently, and the burly man stood up from the sofa: "Hate, Hu Ai, don't pull me." ”

Hu Ai smiled and wanted to say, "I didn't use any strength, okay?"

And as the good man's big hand was touched, he jumped to his feet excitedly, and urged in his mouth: "Little brother, use force, use some more force......"

After a long time, Zhuang Ying "tried" again and again, until Hu Ai pulled her away.

Ji An put down his clothes, looked at Zhuang Ying, who was red-faced, and said in his heart: "Why do you feel like I've suffered a loss?"

At this time, Ji An's mobile phone rang, looked at the caller ID, and muttered, "Why are you calling me now?"

After listening for a while, Ji An's face sank: "Are you okay? What about Oudi? Okay, I'll come over right away." ”

He turned around and said, "Zhuang Ying, I won't send you to the station for a while, the base is a little trivial, I want to go first." ”

After speaking, Ji An called the fat tiger and rode away on the little electric donkey.

In the room, Zhuang Ying was still unfinished and said, "Xiao Ai, let's teach the little brother something else next time, right?"

Hu Ai's face was dimpleed: "Okay, what do you want to teach, let's study it carefully." ”

Good man: "For example, the leg muscles exert force, and the arms, yes, yes, yes, and the chest muscles, the chest muscles, and ......"
