"Skipping rope and squats for a while, I'm not in good shape now, and doing these two hurts my knees too much."

"And HIIT and rhythm running... Let's run at the tempo! ”

Although HIIT has a low reward threshold, on average, you can earn 0.1 ability points for each completed completion.

But Zhang Beixing knew that this thing was quite tiring.

Even Lao Dong, who has the best physique in their dormitory, is panting like a dog after jumping HIIT twice.

Not to mention that his physique is far inferior to Lao Dong.

It is estimated that if you can't hold on to it again, you have to lie on the ground and lie on the ground.

Rather than doing it uselessly, he might as well try his hand at tempo running.

With that in mind.

Zhang Beixing said, 'I'm going for a run,' and left the dormitory and headed to the playground.

Look at his departing back.

The three people in the room were stunned, and then VX sent a message to Zhang Beixing, asking him to bring a meal when he came back, so he put on headphones and started the journey of reverse division.

…………………………

Rhythm running, also known as aerobic threshold running, or lactic acid threshold running.

It is a training session used to improve endurance and running speed.

It's different from the usual casual jogging and all-out sprints.

Tempo running is somewhere in between and is often used to push the boundaries between aerobic and anaerobic exercise.

At its core, the lactic acid pushes at the same rate as it dilutes when running.

To put it bluntly, it's about controlling the intensity of your running so that it's just above the maximum threshold your body can tolerate.

Generally, people who enter this state will have a feeling of 'comfortable pain' when running.

But as long as you can persevere, the improvement you get is by no means comparable to ordinary running.

…………………………

After checking the relevant information of the rhythm run through his mobile phone, Zhang Beixing suddenly realized.

He moved his body, took a few deep breaths, lifted his spirit, and then opened his legs and ran.

The playground track of Shi Ke University is a standard 400-meter runway.

If Zhang Beixing wants to complete the task of rhythm running, he needs to run twelve and a half laps around it.

But because he is only now in contact with rhythm running, he is not yet proficient.

The final result was definitely more than twelve and a half laps expected.

In the first lap, Zhang Beixing took a test and ran normally, without any change in the system progress.

In the second lap, Zhang Beixing began to try various running rhythms, and after one lap, he was out of breath and sweating, but the progress on the system panel changed from 0M to 50M.

This change has made Zhang Beixing very encouraged and hopeful.

So he continued to run, groping his rhythm and finding his form.

The third lap...

Lap 4...

Running until the fifth lap, Zhang Beixing was panting like a cow, feeling the 'comfortable pain', and the thought of giving up could not help but rise in his heart.

But look at the ever-increasing progress on the system panel.

Thinking about the inhuman suffering I suffered in my previous life because of my illness.

He gritted his teeth again and continued to run.

And this run, that's twenty minutes!

……………………

With the complete exhaustion of physical strength.

Zhang Beixing, who had been running at a pace, finally couldn't hold it anymore and slowed down.

It was as if he had just come out of the water.

Nothing was dry on the body.

His face was flushed, his legs trembled, his mouth was dry, and he was dizzy......

Zhang Beixing felt that his life was half gone.

But Rao is like this, but his task is still not completed.

[Suggestion: Rhythm Run, Difficulty D, 0.5 Ability Points for every 5km run, current progress: 4.13KM/5.0KM]

There are still more than 800 meters left, that is, two laps.

Zhang Beixing also wanted to run hard and receive the reward of the system.

But his weak body prevented him from doing so.

In desperation, he could only choose to rest and wait for his strength to recover before continuing to run.

"Lao Zhang, do you want to drink water?"

Just as Zhang Beixing was walking slowly around the playground to soothe his muscles and heart rate, a crisp voice came from his ear.

Zhang Beixing was stunned for a moment, and when he looked around, he saw a girl with snow-white skin coming to him at some point, with a small cart next to her, and a bottle of mineral water with water droplets in her hand.

"Lin Siqi?"

Looking at this girl, Zhang Beixing raised his eyebrows and said the other party's name.

Even if he was reborn, he didn't have much of an impression of his college classmates.

But she is the only one, Zhang Beixing still remembers it very deeply.

It's not that I have feelings for her, but Lin Siqi, who is really special.

As a pure and lovely southern girl.

From the first time people saw her, their impression of her was that she was a soft and weak little girl who did not touch the spring water with her fingers.

And it's such a little girl.

But since the beginning of his freshman year, he has been pushing a small cart and setting up a stall on the playground!

At a time when the other girls were busy learning makeup.

Lin Siqi travels several miles every day to buy goods.

While other girls and boyfriends are you and me.

Lin Siqi is working hard to promote her products.

No matter spring, summer, autumn or winter, as long as it doesn't rain, you can see her petite figure on the playground.

Ice cream drinks, snacks and department stores.

That little cart is like a bottomless pit, she can find it for you as long as you want!

But then, I don't know why, she suddenly stopped setting up a stall.

It's a pity that such a beautiful scenery is missing from the campus.

……………………

"Drink, bring me a bottle of energy drink, I want ice."

Pulling his thoughts back, Zhang Beixing looked at Lin Siqi and spoke.

Although he felt that Lin Siqi was interesting.

But it's just interesting, for him, the top priority now is to complete the task of the system and see if the effect of that ability point is in line with what he thinks

"Energy drinks? Okay, thanks to six dollars, VX or Bearer? ”

Listening to Zhang Beixing's words, Lin Siqi was full of smiles, she took out a bottle of functional drink from the small cart, handed it to Zhang Beixing, and then skillfully took out the payment code and put it in front of Zhang Beixing.

Looking at this bottle of functional drink that can be obtained for five yuan in the supermarket, it has directly risen by one yuan here.

Zhang Beixing couldn't help but say, 'It's really black', and then took out his mobile phone, found Lin Siqi's friend in VX, and sent a red envelope.

Lin Siqi didn't care about his words, but after receiving the red envelope at the speed of light, she looked at Zhang Beixing and asked, "Speaking of which, Lao Zhang, why did you start running recently?" What did the other day irritate you? ”

Zhang Beixing took a sip of his drink, a little speechless.

He naturally knew what Lin Siqi was talking about, so he said: "No, it's just a breakup, it's not enough for me to take it to heart, I just want to lose weight and fitness." ”

"Oh, that's it, that's okay, I thought you were really empty...... But if you want to lose weight through running, you have to adjust your breathing, your breathing is too messy, and you will have to be tired and choke after running for a long time. ”
