Charlie Camus steps off the courts at the Canberra Tennis Centre exhausted.
"I've got to work hard to keep up with him," the 14-year-old emerging tennis prospect said.
Him being Nick Kyrgios, the ATP's No. 48 ranked player in the world, the Australian star of whom the public perception has changed rapidly over the past year.
Camus spends about 16 hours a week on the court with gym sessions on top of that, but these moments with 25-year-old Kyrgios are the ones he would never miss. They are "invaluable".
Kyrgios has been on the court with some of the greatest we've seen and won. Think Rafael Nadal, Novak Djokovic and Roger Federer.
Now he is inspiring Camus to follow in his footsteps as the young gun begins to forge his own legacy as a tennis player.
"I want to play all the grand slams like him and travel the world," Camus said.
"It's invaluable, it's extremely good. Not just tennis-wise, but also telling me about the pro circuit and what life on tour is like. He said it gets quite lonely, but it's good and he's liking it.
"[Hitting with him] was good. Tiring. I've got to work hard to keep up with him. I hit with him quite a bit, over the past six months it has been about once a week."
So he learns about life on tour. But what about on the court? Kyrgios is renowned for giving fans a primer for the front-facing tweener.
Search his name on YouTube and you find yourself bombarded with highlight videos boasting trick shot compilations labelled "epic" and "brilliant". But his sessions with Camus have stopped short of working on those eye-catching moments.
"He just says don't try to copy him because I don't have his hands," Camus said.
Camus is 11 years Kyrgios' junior. In 11 years the Olympic Games may well be coming to Brisbane after the International Olympic Committee identified the Queensland city as its preferred bidder for 2032.
He has had a racquet in his hands since the age of three and would rush home from school to mimic the likes of Jo-Wilfried Tsonga and Gael Monfils.
Camus has wanted to chase his dream of becoming a professional tennis player since watching the Australian Open years ago. Now Camus has the Olympics in his sights.
"Absolutely, it's a goal. I would love to play for Australia at those Olympics. It would be extremely special, it would be so good," Camus said.
"At the moment I'm doing about 16 hours a week of tennis and about four or five hours in the gym. I'm doing quite a lot.
"I've gotten a lot stronger, I've got taller too. Shots become a lot more powerful and serves become bigger and faster.
"I'm hopefully going to get a wildcard into some pro tours in Canberra in March. After that there is nationals in Canberra too in April, then after that I'll hopefully play some ITFs around Australia."
