Sports University training room.

Today was the last day Feifei Yu was here. Now that her weight had dropped down to 62kg, she no longer needed to lose weight. Tomorrow she would go back to national team, then go to Australia for special training.

Feifei Yu was looking at Dai Li, reluctant to part ways with him. Her eyes were full of tears. She had been training with Dai Li for a month, and although they hadn't built a tight teacher-student emotional bond, they did have a deep friends.h.i.+p. They were of similar age and shared many interests in common, so they had became good friends.

Dai Li had successfully helped Feifei when she was at her lowest point, and now she had rebounded to her original condition. She completely trusted Li, and really appreciated his timely help. Now they were going to say goodbye, and naturally Yu showed her unwillingness.

"Alright, Feifei, don't cry. Next Spring Festival, after you return to Qingcheng City, we can meet there! Now let me show you out," Li said, comforting Yu.

Watching Feifei walk away, Dai Li gave a long sigh pityingly. He was also not looking forward to parting ways. He was able to gain a lot of experience value from Feifei Yu, and without her he had to find dozens of first-cla.s.s athletes to make up. In addition, his upgrading speed would slow down.

World champions could not be found everywhere. When there was an Olympic Games, more than thirty new world champions could be found. But during the other years that did not have any worldwide compet.i.tions, there would only be a few world champions. Feifei Yu was a world record holder who was on top of the world. Li was going to have a hard time finding a subst.i.tute who was as good as Yu.

"At least I just finished guiding her through the slimming exercise one last time. Now my experience value is ready for another upgrade." Li smiled with relief. He had just become a second-rate coach seconds ago. Although he was still at the beginning stages, it was good news to him.

According to the System information, once one upgraded from a soph.o.m.ore coach to a junior coach, his training effectiveness would have a substantial increase. Even though his performance might not be as good as famous chief coaches', he would outperform other ordinary coaches on the national team without a doubt. If Li was indeed allocated to the national team, he would be more than ready to handle whatever tasks were thrown at him.

The downside was that it required 10,000 experience value for one to move from the second-rate preliminary phase to the intermediate phase. Based on Dai Li's current upgrading speed, even including summer and winter holidays, it was going to take two years to obtain the requirement.

Dai Li couldn't stop complaining. Last year, when he had just gotten the System, it had only cost him 100 points to upgrade. But now after only one year, the minimum value amount to upgrade was 100 times greater, and it was only for moving up from the preliminary phase. According to this growth rate, it would be another 100 times increase if he would like to move on.

"It only cost me 1,000 points, 2,000 points, and 5,000 points to upgrade when i was a third-rate coach. But look how much I have to pay now! Will it cost 20,000 points when I reach second-rate senior? How about top-level coach? Should I obtain 50,000 points then? The total amount for the whole second-rate will be 80,000 points. It will take me two years to gain 10,000 points. Let me see...Sixteen years! I need to spend sixteen years to finally obtain 80,000 points! Such a long time! I will be entering my forties when I finally reach the top level!" Li made a bitter face.

"Sixteen years, I can feel the pain now...Whatever, I will let it be. Why bother? System, show me my rewards!"

"You have reached a brand new rate, so this time you will receive a big gift pack!" said the System.

"A big gift pack? Huh, not bad. I hope it is good enough to comfort me. But what is the difference between this one and the previous ones?" Dai Li asked immediately.

"Do you remember when you received a newbie pack when you were still a beginner? There were two items. That's what the difference is. A big gift pack contains two rewards, while an ordinary pack only has one gift for you," answered the System.

Upon learning that he would receive two rewards, Dai Li's face brightened. He couldn't wait to summon the gift pack and open it. There were indeed two rewards.

"Books! Like the last time!" Dai Li felt nervous. Last time, Li was given a book of Slimming Exercises. It was useless. If he hadn't met Feifei Yu, he would never have had a chance to use it. Unfortunately, this time the same thing had happened again.

"Last time it was a shxtty slimming exercise, I wonder what I will get this time. I hope they are useful." Li checked the cover of the book.

"Fat Loss Exercise!" Li read the t.i.tle and showed his disgust with a scowl.

"Slimming Exercise and Fat Loss Exercise, are you kidding? Why would you give another useless reward? Were they buy one, get one free?" Dai Li wanted to swear.

"I think I can feel your... anger?" asked the System.

"This is bullshxt! You have lied to me twice, how can I keep calm? Fat Loss Exercise? I already have the Slimming Exercise, I don't need this rubbis.h.!.+" Li was trying to suppress his anger.

But the System remained calm. "As a physical training major, I'm sure that you know the difference between losing weight and losing fat?"

He of course knew the distinction between losing weight and losing fat. People who didn't know much about the difference would think losing weight meant losing fat, and that less weight meant less fat. To amateurs that made sense.

To professional athletes, however, such an understanding was ridiculous. In fact, there was a huge difference between losing weight and losing fat. Weight loss included losing fat and muscle, but losing fat aimed only to reduce fat and decrease body fat percentage.

Physiologically speaking, losing too much weight would cause some negative effects, such as the decline of one's basal metabolic rate, degradation of immunity functions, getting tired easily, etc. Comparing the two, losing fat was a safer and healthier choice. Muscles would be maintained, or even increase, while fat would be eliminated.

The System then asked Dai Li, "Most people think that athletes should maintain a quite low body fat percentage, but as a professional, you know that not every athlete wants to get rid of fat, right?"
