Dai Li stood to the side awkwardly. The movements of the weight loss exercise looked like the broadcast exercises that students did in school a lot. It didn't surprise Li that Coach Xu thought it was a broadcast exercise. He didn't explain because he knew it wouldn't change anything. Only the people who had practiced the exercise with him would know about its results.

However, it annoyed Feifei Yu a little it. The exercise had helped her lose a few kilos in a short period of time. She had no doubts in both this exercise or in Dai Li. She stated, "Coach Xu, this is not a broadcast exercise, but a weight loss exercise."

"Weight loss exercise?" Coach Xu frowned and continued asking, "Where did you learn that from?"

"Coach Li taught me." She pointed at Li and continued, "Excuse me, I forgot to introduce you two. This is Coach Li from the provincial sports university. He has been helping me train these days."

She turned to Dai Li after she finished. "Coach Li, this is Coach Xu from the provincial swimming team. He is also my esteemed coach."

"I've heard of Coach Xu for a long time. It's nice to meet you." Li stretched out his hand immediately.

Li had heard about him many times through Feifei Yu. His name was Zhongyi Xu, an ex-swimmer. He became a coach after he retired, and his wife was also a famous swimming coach. Feifei Yu began swimming around the age of six. Mr. and Mrs. Xu were both working at the sports school at that time. She became Zhongyi Xu's student, and was treated like she was their own daughter. After that, Yu got into the provincial team, while the couple was promoted to swimming coaches for the provincial swimming team. They continued teaching her until she joined the national team. Zhongyi Xu was also promoted to the main coach of provincial swimming team because he had cultivated the world champion Feifei Yu. He was one of the best, even among the entire provincial sports team.

A few days before Feifei Yu had just come back to the provincial team, the couple had just brought some of the athletes to the north to train. He had come back to Qing City this morning, and the first thing he did was come to find his talented student Feifei Yu. Yet he had only just found out that she was here practicing weight loss exercises.

With Li's hand still in the air, Zhongyi Xu didn't show any politeness. He snickered, "What a messy exercise. This is the official training room, not a gym!"

As a professional coach who worked for more than 10 years, he didn't believe anything like weight loss exercises. To Zhongyi Xu, it might be effective for ordinary people, but not athletes. It was just a waste of time.

The mechanisms in weight loss exercises were still about consuming energy. No matter how many calories the exercise could burn, it could never compete with high intensity training for athletes. To Xu, the movements of this exercise looked exactly the same as the broadcast exercises that were meant for primary and middle school students. He felt that this exercise couldn't even make people sweat.

Li felt his malice. Xu stopped him just as he was about to explain. Xu stared at him and said with a very strict tone, "Coach Li, you are pretty young. How did you become an official coach at the sports university?"

"I'm just an a.s.sistant coach as of right now," Li explained immediately.

"An a.s.sistant coach." Xu suddenly changed his expression, and looked as if he was trying to contain his anger. He shouted in a low tone, "You are an a.s.sistant coach, how dare you train Feifei Yu? Don't you know that she is an Olympic champion, the world record holder? How dare you make up some weight loss exercise? Do you think it's a gym here? You think the Olympic champion is a young lady who practices yoga in the gym? What's wrong with your sports university? How could they make such a big mistake to send an a.s.sistant to train her? I'm not letting this go!"

"It's not like that, Coach Xu. Could you please listen to me—" He was interrupted by Xu in the middle of his sentence.

"Explain? I'll need an explanation from your boss! In your school, the a.s.sistant coach has the qualifications to train a world champion? So does that mean the a.s.sistants in your school are better than the coaches on the national team? Your school has to give me an official explanation!" Xu said seriously.

From his perspective, he couldn't tolerate an a.s.sistant coach being involved in Yu's training. After all, she was a world champion. She should have the best coaching team in the nation. A low-level coach might not only be useless to her, but do her a disservice. If there was something wrong with the training method, it could lead to an injury. That was why Xu would never tolerate a young a.s.sistant coach training Yu.

"I just want to help her lose weight," Li explained.

"Lose weight? With your broadcast exercise? Do you think you are teaching a primary school student? They hired many physical strength coaches and even nutritionists from universities. Even they couldn't help her lose weight. You think your shxtty exercise will help?" Xu shouted in anger.

Dai Li was annoyed by his word "shxtty." He changed his expression immediately and spoke without showing any sign of superiority or inferiority. "I can tell you honestly that my exercise works better than those physical strength coaches from national teams and nutritionists from universities!"

"You know nothing!" Xu said coldly. "I have no idea how a loser like you could be an a.s.sistant coach in the sports university. How dare you compare yourself to the coaches from the national team? How dare you put yourself in the same sentence as nutritionists from universities? You don't understand the complexity of things at all! I can say that you can't even compete with one of their strands of hair!"

"Actions speak louder than words. Let's look at the real results. I can help her lose weight. I can make the number on the scale go down, but the coaches from the national team can't. Neither can the nutritionists from the universities. That means I'm better than them when it comes to helping people lose weight," Li said, going t.i.t for tat with Xu.

Xu was extremely angry, and was breathing deeply. "Sure. If you say so, then show me! Let me see your 'real deal!' Don't just brag and bark. Everybody knows how to bark, but not everybody knows how to bite."

That was all Li wanted. He asked directly, "Coach Xu. Do you remember what her weight was before she came back to Qing City?"

Xu hesitated and said, "About 70kg!"

"Alright. I'll show you her weight now." After he finished his sentence, he pointed at the electronic scale, which was not far from him, and said to Yu, "Feifei, get on that scale and show Coach Xu if my exercise works or not!"
