The all-round academic master's girlfriend

"Actually...Xiao Xi, your running posture is still not quite standard. If you can improve it, you should be able to run 0.1 to 0.2 seconds faster."

"Really? Wait, brother, you were 50 meters away from me at the time, and you could actually see that my movements were not standard."

Xia Jinxi said with some surprise, even if her starting action at that time was not completely standard, it shouldn't look much different, and her brother could actually see it from such a distance?

"I have good eyesight."

Tang Yuze replied calmly.

"Anyway, do the same action again first."

"it is good."

Xia Jinxi once again put her hands on the ground and did a crouch start according to her impression of watching TV, but in fact her posture was not standard.

"Pay attention to raising your hips, so that they are at the same height as your shoulders or slightly higher, and your shoulders are slightly beyond the starting line, so that your center of gravity can be properly moved forward."

According to what her brother said, Xia Jinxi began to correct her posture little by little. It must be said that sports can really show a person's figure. Just like now, after Xia Jinxi's crouch start action has been gradually perfected, the streamlined shape supported by her raised buttocks and body is a beautiful landscape that belongs only to Tang Yuze.

"Relax your shoulders a little more and let your weight fall mainly on your arms and front legs. This will help your body get out of a static state quickly and gain forward momentum."

Xia Jinxi tried her best to control her center of gravity as Tang Yuze said, but the posture of lying on the ground with her hands made her subconsciously exert force on her shoulders, making it difficult for her to adjust her balance.

"Relax, this pose doesn't require you to put both hands on the ground, just touch the ground with your fingers."

In order to correct his sister's starting posture, Tang Yuze patted her shoulder gently. There seemed to be some kind of magic hidden in his gentle voice, which allowed Xia Jinxi to quickly adapt with her body. She no longer exerted force on her shoulders, and her center of gravity was pressed back to where it should be.

"Very good, that's the feeling. Let's feel it slowly first. We'll try running twice more later to see the effect."

"it is good."

Then, Tang Yuze corrected his sister's starting posture step by step.

At the end of the day, Xia Jinxi was finally trained by Tang Yuze to the point where she could run in 7 seconds, making rapid progress.

It seems that his teaching talent is not only reflected in teaching.

"So, your junior high school PE teacher didn't even teach you the squat start? That's impossible."

"I was taught, but I just remembered the general posture based on my memory and didn't really listen carefully. After all, for the high school entrance examination, girls only need to run 50 meters within 8.2 seconds to get full marks."

In other words, because the full score standard for the short-distance running in the high school entrance examination was too low, Xia Jinxi had no motivation at all.

But it is true that, judging from the current situation, although there are calls from all over the country to improve students' physical fitness by increasing the proportion of physical education subjects in the high school entrance examination, in fact, the full score standard is generally set very low, and the invigilation is not very strict. Therefore, it is simply a pipe dream to want to rely on good physical education to widen the gap between yourself and your classmates in the high school entrance examination.

"Would you like to try long-distance running? But there aren't long white lines in this small park, and the roads are crooked, so it's hard to calculate the distance accurately."

"We should try, but don't think too much about it. Let's just run around. How about we jog for about half an hour, find a place to play for a while, and then go to have lunch?"

"Okay, I'll run with you. Although this park is not big, the structure is quite complicated. Don't get lost."

"Okay~"

In the sunshine of an autumn morning, the brother and sister jogged side by side in the park. No matter which path they took, they eventually returned to the entrance.

"Huh...Huh...Brother, you have such great stamina. You've been running for so long and you're not even out of breath."

When the time was up, Xia Jinxi, who was sweating profusely, spoke to Tang Yuze intermittently.

"It's not bad. Our speed just now was at most a little faster than the boarding students' morning exercises. It's not difficult."

Although it sounds easy, for most people, even if they jog at this speed for half an hour, they will definitely feel rapid chest movement and difficulty breathing in and out. Tang Yuze is also having difficulty breathing now, but he still decides to endure it for a while and look cool in front of his sister.

"Oh, no!"

At this moment, Xia Jinxi's face was flushed because she had just completed a long-distance run. Countless beads of sweat hung on her body, which were clearly visible under the sunlight. Even her slender, white and tender thighs turned from white to shiny, exuding a different kind of temptation.

It’s a pity that Tang Yuze didn’t bring a handkerchief when he went out today, otherwise he could use it to help Xia Jinxi wipe her rosy shoulders.

Xiao Xi's smooth skin must feel very good...

No, even if she brought a handkerchief, she should have wiped it herself. What on earth was I thinking?

Tang Yuze shook his head and quickly dispelled the evil thoughts.

He found that something was wrong with him recently and he kept thinking about things he shouldn't think about.

Or maybe those people outside were too stupid. They always mistook Tang Yuze and Xia Jinxi for a couple, making him feel like he could really be Xiaoxi's boyfriend.

"Eh? Tang Yuze and Xiao Xi, what are you doing?"

Just at this moment, a female classmate passing by saw Tang Yuze and Xia Jinxi here.

The girl was wearing a simple white T-shirt and a pair of dark blue jeans, the trouser legs swaying slightly with her light steps.

She is half a head taller than Xia Jinxi and a little shorter than Tang Yuze. Her slender figure and sporty outfit give her an inexplicable queen-like aura.

If Tang Yuze remembered correctly, this girl in their class was called Gao Xiaowen.

But he only remembered the name, after all, there was not much intersection between them.

"By the way, she calls you Xiao Xiye, are you close to her?"

"Hmm... it's OK."

During the first week of school, quite a few girls talked to Xia Jinxi, and Gao Xiaowen was the one who came most frequently.

Every time she came to talk to Xia Jinxi, she would try to touch Xia Jinxi's little head.

Every time this happened, Xia Jinxi would say that she only let Brother Yuze touch her head, leaving Gao Xiaowen with only an awkward smile.

Gao Xiaowen was about to come up and say hello, but she found that something seemed wrong.

At this time, Xia Jinxi's face was flushed and she was breathing heavily, with some sweat on her thighs that had not yet evaporated, while Tang Yuze's expression was one of satisfaction.

Gao Xiaowen looked behind them carefully again. There was a sparsely populated park and dense woods...

Well, well, well, even if you are childhood sweethearts and have a close relationship, you can’t start a war in broad daylight!

"Morning exercise."

"Morning exercise? What kind of morning exercise?"

Gao Xiaowen had completely misguided her thoughts, but the brother and sister had not yet realized what she was thinking.

"It's just a normal morning exercise. The sports meet is coming up soon. I asked my brother to help me adjust my posture. It's a lot faster than before."

"A lot faster? Isn't it better to do things slower?"

It turns out that although Yu Ze looks like she has a pretty good figure, her figure in that area is not that ideal?

The more Gao Xiaowen listened, the more confused she became, and she selectively omitted the word "sports meet".

"Hmm? For sprinting, you should go as fast as possible. Every tenth of a second is crucial to victory or defeat."

"Short...sprint?"

"Xiao Xi said she wanted to work out a little before the sports meet, so I came out to practice running with her."

Tang Yuze said calmly. He always felt that something was wrong with Gao Xiaowen, but he didn't notice what she was thinking.

"Sprinting...? That's good."

Gao Xiaowen sighed.

How could her thoughts be so dirty?
