But this time around, he was teaching the world a martial arts lesson.
Head coach at Pure Jiu Jitsu Southern Highlands Tony Pycroft became the Internationals Masters Champion at the 2019 International Masters in Tokyo, Japan.
Pycroft walked away on June 16 with a silver and gold medal all while impressing fighters from around the world.
It's been a long and difficult road which began over a decade ago, but Pycroft still has honeymoon period passion for his art.
"This will be my tenth year I've been studying Jiu Jitsu," Pycroft said.
"I initially got into it just for a healthier lifestyle. It interested me because, although I'm not a small person, it is based around a smaller person defeating a bigger person.
"The efficiency of Jiu Jitsu appealed to me more then other martial arts.
"There's not a great deal of striking which makes it different to your traditional martial arts like karate or taekwondo. It's more about submission holds and dominant positions. The idea of controlling someone without punching or kicking them really appealed to me."
Heading over to Tokyo for the International Masters was a massive gut check for Pycroft. A lot of sacrifice and preparation went into the opportunity.
"It was pretty daunting," Pycroft said.
"From January 1 of this year to now I've dropped close to 20kgs. A huge weight drop and a lot of lifestyle changes. I've been strict with my nutrition and changing bad eating habits. There was also a lot of strength and conditioning.
"This competition was extremely tough. I faced competitors from all around the world. From Brazil, Canada, Japan and other parts of Europe.
"I feel like after this tournament I'm right where I need to be to position myself for success at the World Championships.
"I was very focused and my next big tournament will be in Las Vegas this August. That will really be the big test."
Pycroft competed in two competitions whilst in Japan. He won the silver in his weight division and the gold in the open. It was all worth it for that feeling at the top of the podium.
"It was really, really awesome," Pycroft
"I got beaten in my weight division by one of the black belts, who was ranked fifth in the world.
"He beat me on points, he took me down and got awarded two points for that. But I came up against him in the semi-finals of the open weight division and I ended up beating him quite convincingly.
"That was a very sweet victory. Although it wasn't the final, it was just as sweet as the win in the final."
