Xin Xiaotian was lying on the bed, and a question vaguely came to mind, so she picked up her mobile phone and used "hiit" as a keyword to search for related articles.

When I heard Daqiang introduce this sports concept to her before, I felt that it was very fresh and reasonable, and I didn't think much about it after that, but today I heard Sun Jiashi say this, combined with her own experience in these classes, she suddenly felt the need to see if there was anything contrary on the Internet.

I originally thought that I would have to flip through it to find the opposing viewpoint, but as a result, I found that the positive introductory article and the negative discussion article were almost half to half.

That's interesting.

Xin Xiaotian clicked on it one by one, read it quickly, and the positive introduction is basically the same as what Daqiang said, with various benefits, and it can also save time; The negative articles are: is HIIT reliable; whether HIIT is really better than aerobic; whether HIIT can really replace running; Can HIIT really achieve the dual effect of gaining muscle and losing fat? Misconceptions about the HIIT movement, and so on.

Xin Xiaotian looked at it for a while, only to feel that there were more and more black lines on her head, what about the cheating father, why can't you make people move to lose weight, why are so many exercise methods said like this and that, controversial?

After reading it, Xin Xiaotian put down her phone and briefly summarized the opposing party's views in her mind:

At present, no institution can prove that HIIT can burn more calories than traditional aerobic exercise, and HIIT is a miracle for weight loss. It is likely to be due to a misinterpretation or misreading of some serious theoretical knowledge.

In addition, not everyone is suitable for HIIT training, because one of the characteristics of HIIT training is that during the high-intensity period, the heart rate is required to reach 90%-100% of the physiological maximum heart rate, which may have a certain risk, for example, people with arrhythmias should be cautious to avoid this type of exercise. So as not to ...... the heart rate is too high.

Furthermore. Due to the intensity of HIIT training, the recovery period required by the body is longer, and it is generally not recommended to train in this way for two or three days in a row.

Oh, no wonder Daqiang said. It's best to go every other day.

……

Although once again, the more I look at it, the more confused I become. But. In view of these opposing views, Xin Xiaotian felt that it was better to build a YÌ Sun Jiashi first and not to do HIIT training for the time being.

Look at the time. It is estimated that Sun Jiashi has fallen asleep at this time, so he has not sent him a message, and this problem is not very urgent, and it is not too late to talk about it tomorrow or the day after tomorrow.

Putting down the phone, Xin Xiaotian still didn't feel sleepy, and stayed for a while, she called the system Xiaolan in her head.

"There are no tasks in this system at this time." Xiaolan didn't show any tone, showing this line of words.

"There's something I want to ask you, or I want to discuss it with you."

"Please."

"I ...... I am going to ...... from tomorrow Started to help Sun Jiashi lose weight, if you can help him lose weight, do you have any corresponding tasks and rewards here? Xin Xiaotian wanted to ask for a task to do by the way.

Of course, this is to earn more benefits, and the points are okay, seeing that the points of the visual measurement function are saving so slowly, she is also a little anxious.

"None." The system replied very briefly and crisply.

"Please...... This is also related to weight loss, can't you design a few tasks and give some related rewards? Xin Xiaotian began to use her grinding efforts.

"I've never seen you ask for a mission." The system finally seized the opportunity to "tease" her once.

"So there should be a double reward." Xin Xiaotian pretended to be cute, but I don't know if the system can see it.

"This system only cares about girls, not men."

"What is your answer, actually making a difference?"

"There are no tasks related to this system."

"Hey, you are a super beautiful life system, and you are not a beautiful life, why do you prefer women over men?"

"If you are interested in helping your friend named Sun Jiashi lose weight, this system likes to hear about it. But for you, it's all voluntary. There are no related tasks in this system, but the necessary material support can be provided, and if necessary, you can apply to this system. ”

"You mean you can give me something you can use, but you don't have the tasks or money to do it?" Xin Xiaotian repeated it generally.

"Yes."

Xin Xiaotian thought about it for a while, and felt that this was actually good, and it could be regarded as a gain, so she said, "That's it...... Okay, so what can you give, is there anything good that you can take out and support right now? ”

The system was silent for several seconds before it said:

"According to the actual situation of this friend, a 'super function slimming bracelet' can be rewarded."

"Can you not add the word super?" Xin Xiaotian couldn't help but spit out the names of these things again.

"It has to be added, it's all super." The system is emphasized in an unquestionable tone.

"......" Xin Xiaotian was a little speechless, but then she moved out of her cleverness and asked, "How many good things do you have, why don't you take them all out at once, so that I can have more good ways to choose." ”

"I can't." The attitude of the system is indifferent.

"Is there only one bracelet to slam the door, and how much of a role can this make?"

"I've used it to know myself." The sentence is still concise, I don't know if it's because it's too late.

"Please choose the color of the bracelet, choose any color from all the colors you can think of." The system continues to display.

Xin Xiaotian thought about it and chose a low-key dark gray.

"Business Grey. Boring. While confirming the color, the system once again expressed dissatisfaction with Xin Xiaotian's aesthetics.

Xin Xiaotian didn't care about this, she was more concerned about the substance, so she cheekily said, "Give me something, he's so fat." ”

"Yes. Bonus: A set of super slimming waist cushions. This time, the system suddenly expressed itself very crisply.

Xin Xiaotian thought that she would have to be verbose for a while, but she didn't expect the system to agree so quickly, so she was a little surprised, and couldn't help but ask in her heart: "Xiaolan, do you have a universal small factory, the kind that can produce anything?" ”

"No comment."

"Please sign for the above rewards tomorrow morning, the system will accept the application, and rest early." After saying that, the system disappeared instantly.

……

"Okay, I got two things for Sun Jiashi, it's not bad, it should be very useful......" Thinking of this, Xin Xiaotian finally fell asleep with peace of mind.

The next morning, Ke Yiwan had just walked for a few minutes on her front foot when Xin Xiaotian's mobile phone rang, it must have been a courier.

She ran downstairs with some anticipation, and sure enough, it was the courier.

A slightly flattened cardboard box, fortunately not too big.

When I took it back and opened it, there were two cushions in the box, one of which was packaged with the words "dedicated to office chairs" and the other was written to be dedicated to car seats.

It turns out that there are two in a set, one in the office and one in the car, and the system is really thoughtful.

After taking out the cushion, I saw that there was a small box inside the big box, nothing was written on it, and when I opened it, I saw two bracelets, one of which was the business dark gray she chose, and the other was ...... It should be a fluorescent green color that the system forcibly attaches according to its own aesthetics...... (To be continued.) )
