"Mom, I'm with Wang Wuyun, we made an appointment with classmates to go outside to play for two days, so I won't come back for the next two days, really, I don't lie to you, don't you know me, what bad things can I do, well, I have the money, I usually save some of the pocket money you gave me, it's enough, I'm not here, it's just convenient for you and my dad to live in a two-person world......" Zhu Yuexin squeezed his eyebrows at Wang Wuyun while making a phone call, that look made Wang Wuyun next to him look at it and couldn't help but snort," Okay, okay, I'll give the phone to Wuyun, you talk to him, see if I lied to you......"

Zhu Yuexin handed over his phone to Wang Wuyun as he spoke, squeezing his eyes, Wang Wuyin jumped off the double pole and took the phone, "Hey, Auntie, it's me...... Well, Yuexin is with me...... Yes...... Yes...... We're working out in the gym right now, right...... We also made an appointment with classmates, and we are going to play outside for two days, Auntie, don't worry, there are a lot of people, and it's not too far away, Auntie, don't worry, I'll look at Yuexin...... Well, okay...... Ok ......"

After hanging up the phone, Wang Wuyin threw the phone to Zhu Yuexin, "Okay, your mother asked me to watch you, she still doesn't believe that you can exercise, you open a video call yourself, let her take a look at her before she can rest assured......"

"My mother is really, she doesn't believe me but believes you, her elbow turns out......" Zhu Yuexin said, he still turned on the WeChat video call of his mobile phone, took the mobile phone to his and Wang Wuyin's faces, and then swept around the gym, "Mom, I see, although it's night, but we're in the gym now, your son I'm working out, but I didn't go to any messy places, I didn't lie to you, there is no boundary, don't worry, I'm hanging!"

Seeing Zhu Yuexin hang up the phone, Wang Wuyun pointed to the double rod, "You come and try this, and exercise for a while like I did just now......"

Zhu Yuexin walked over, grabbed the double rod with both hands, as soon as his hands were forced, his feet jumped, and he went up and made two movements, but his body was a little stiff and his movements were not coherent, and after only two minutes of trying, he jumped down, with a bitter face, rubbing his arms and sore thighs, "Wuyun, it's really strange in the gym of your villa, there are a lot of muscle-building equipment in other people's gyms, why do you get these few things in your gym, it looks like a gymnastics room for gymnastics, and there is nothing for other exercise equipment!"

"I took you to the gym today to tell you about this, you are also exercising at the gym during this time, what do you think of the gym equipment?"

"It's good, I've basically learned how to use it, what's wrong?"

"Then let me ask you a few questions!"

"Okay, you ask!" Zhu Yuexin was very curious, not knowing what kind of question Wang Wuyun wanted to ask.

"The ancient civilization of Huaxia is so developed, especially when it comes to the development and exercise of physical potential, it can be said that it is the first on the earth, our ancient civilization discovered the meridians, acupuncture points, and developed traditional Chinese medicine, qigong, martial arts, guising, food supplements, all kinds of fitness methods, we have also unearthed a variety of cultural relics, stone, jade, copper, iron, everything, as long as almost related to life and enjoyment of our ancient times have corresponding cultural relics, but I haven't seen a few barbells and other things unearthed when excavating cultural relics somewhere？”

Wang Wuyin's question made Zhu Yuexin stunned for a moment, and he didn't know how to answer at all, while Wang Wuyin continued.

"In addition to what I said above, we also have a lot of classics in ancient times, which are still well preserved, but why, the ancient civilization of Huaxia is so developed, the ancients can even eat a crab can invent more than ten or twenty tools, but our ancients have not left many records of relying on any equipment to exercise, and even cultural relics can hardly be found in books? And not only our ancestors in China, but also other countries that developed ancient civilizations, such as ancient India and ancient Egypt, why didn't they leave much fitness equipment and other things? Could it be that the bodies of the ancients were weaker than ours? Of course not, according to many records nowadays, the physical fitness of the ancients was not weaker than that of modern people, but it was possible that it was even stronger. ”

Wang Wuyin's question directly made Zhu Yuexin confused, he thought for a long time before frowning, "Maybe the science and technology of the ancients were not very developed?"

"There are four great inventions in ancient China, the armillary sphere, and the geodynamic instrument, all of which are very complex equipment, do you think the scientific and technological content of these things is not as high as the high-tech content of the fitness equipment you use in the gym?"

"That's ...... Is that...... Those things are all metal, ordinary people may not be able to afford them!" Zhu Yuexin thought about it, and could only continue to explain.

"There is a little truth in what you said, ordinary people can't afford it, but it can't even be used by emperors and nobles, you go to see all kinds of cultural relics and utensils that accompany the emperors and nobles to bury, they are also very valuable, and many of them are ingenious, so why don't these rich and powerful people don't use equipment to exercise? Why don't the palaces of the ancients, the homes of those powerful people, get a few equipment for exercising? Not only the eastern ones don't have them, but the western ones don't seem to have them!"

"Okay, okay, I can't tell!" Zhu Yuexin immediately raised his hand in surrender, and looked at Wang Wuyun with a puzzled expression, "After you asked, I also wondered, why didn't the ancients of Huaxia invent some equipment for exercise?"

Wang Wuyun smiled, " The answer is very simple, not because our ancients couldn't invent it, but our ancients have long known that the most efficient, safest and most practical means of exercising the body is not to rely on external things and equipment, but only to rely on our own weight, just like those strong beasts don't need anything to exercise to become strong, our body's strength, agility and our body weight have a subtle correspondence, as long as we can master the exercise method of using our own body weight, we can avoid relying on external equipment to bring about joint and muscle damage, and at the same time quickly make our body strong and flexibleThe ancients knew this method, so they often needed very few external devices, or nothing at all, to make his own body strong......"

Wang Wuyun said while demonstrating to Zhu Yuexin, and the whole person suddenly fell to the ground and began to do push-ups, introducing while doing it, " For example, the push-up action is the most classic action of relying on your own body weight to exercise muscles, you don't think that this action is simple and easy, in fact, as long as you can do this action well, you can exceed more than 90% of ordinary people, and this push-up action has many variants and tricks after being proficient, and can evolve many movements with higher and higher difficulty levels......"

Wang Wuyun was doing ordinary push-ups at the beginning, slowly, he clamped his arms, gathered the palms of his hands under the abdomen, and put the weight and center of the whole body on the palms below the lower abdomen, and began to do it.

In the second push-up movement, Wang Wuyun opened all his arms, like spreading wings, trying to open the distance between the two palms to support the ground, and began to do it.

After doing a few second push-ups, Wang Wuyun changed to a push-up posture again, this time, the palms of his hands stretched out to the front of his shoulders and head, as if he was doing a five-body bow, although the action was still push-ups, but every time he did it, the whole body arched and fell, just like a feline stretching his waist, the muscles of the whole body were tense, and then completely stretched, Wang Wuyun just did it a few times, and there was a layer of fine sweat beads on his forehead.

Wang Wuyun is constantly demonstrating various variants of push-ups to Zhu Yuexin, including diamond push-ups, curved body push-ups, shoulder blade push-ups, leg-raising curved body push-ups, kneeling plank push-ups, wall plank push-ups, single-leg push-ups, backhand push-ups, finger push-ups, typewriter push-ups......

After doing more than ten kinds of push-ups, Wang Wuyun already had a thin layer of sweat on his forehead, and finally he slowly got up and asked Zhu Yuexin to try it too......
