I suspect the history teacher and the geography teacher are having an affair

Don't look at Wang Kai, who is thin and weak, he usually runs to the gym a lot. 600 yuan for three months, and there is a free class every night.This price is quite affordable for King Kaikai, who earns 6000 yuan a month.

It was almost dinner time that day, and Wang Kai saw Jiang Jianguo take out a thick rubber rope from the drawer, as if he was about to go out.

"Hey? Young people, don't be impulsive, impulsiveness is the devil." Wang Kai hurried over to block the door and refused to let him out. "You go down this rope, and now these children with tender arms and legs will not be disabled by you," he said.

Good guy, he thought Jiang Jianguo was going to beat up the students with this rope ring.

Jiang Jianguo had black lines on his face, "What are you thinking, corporal punishment of students is illegal now." Then he was about to break Wang Kai's shoulders to make him stand aside.

"Huh? You're not trying to scare children." Now it was Wang Kai's turn to be confused. "Then what are you doing with this thing?"

Jiang Jianguo held an orange rubber cord in his hand. The rubber cord was flat, very wide, and had a rectangular cross-section.

"This is called a booster rope...for fitness..." Jiang Jianguo said helplessly.

"Ah? That's it." Wang Kai has never used this thing before, and he has never seen anyone else use it in the gym, so he finds it very novel. "How does this work?" he asked.

"This one, you step on it to support the horizontal bar or something." Jiang Jianguo said while showing Wang Kai the movements. "Oh, you don't understand even if I tell you." Seeing that Wang Kai didn't understand, he stopped explaining and went out directly bypassing Wang Kai.

In fact, Jiang Jianguo used to despise the behavior of street fitness. He felt that it was not only low but also detrimental to the image.But, he recently changed his mobile phone and computer for himself, and his life is relatively tight.Coincidentally, the door card for the gym has expired, and I can hardly afford this meal. How can I have spare money to renew the card.The current Jiang Jianguo is not as rich and young as he was when he invited him to dinner.

However, Jiang Jianguo is one of those people who feel uncomfortable without exercising for two days.Although he is now thin and tall, his body is full of muscles.If he didn't practice these few days, he felt that the flesh on his body was loose, and he thought that he would definitely not be like Wang Kai, with a small belly.But then again, his little belly is kinda cute.

Jiang Jianguo was pulling the horizontal bar on the playground with a booster rope. Although there were many students on the playground, few people noticed him.After all, everyone is trying to lose weight and keep fit, so no one looks down on anyone. Besides, high school time is so tight that there is no time to care about others.

Just as he was holding on, Wang Kai walked over with his neck stretched.

"How much can you hold in one minute with this rope?" Wang Kai asked.

"A group of ten, do it according to the group." Jiang Jianguo didn't stop.

"How many sets in one minute?" Wang Kai asked again.

"A group? Probably about the same."

"Then you said that it is enough to make ten in one minute. Come on, there are only ten." Wang Kai curled his lips in disdain.

"Do one set and take a break before continuing. I didn't count the time."

"Why are you so good, you take a break every minute." I didn't expect Xiao Jiang to be so weak, and I thought he was so powerful, Wang Kai thought.

Now Jiang Jianguo couldn't bear it anymore.

"Do you think pull-ups are sit-ups... It's about minutes..."

"Why not?|ω｀)"

"Within 1 minute of sit-ups, you can lie down when you are tired. Pull-ups, can you hang up when you are tired..."

At this moment, Kai Kaiwang, an entry-level fitness scholar, was finally stunned and had nothing to say.He could only find a place to sit down, and then said to Jianguo:

"Hurry up, I'll wait for you to eat."

"Ang, good."
