A reality TV show. An Olympic sport. Thousands of competitors worldwide.
Few activities can claim all three distinctions. When most people think of competitive sports, “ninja” probably isn’t the first thing that comes to mind. It sounds more like fantasy than reality, more like a video game than an athletic pursuit.
But ninja has quietly become one of the fastest-growing youth sports in America.
According to TV Series Finale, “American Ninja Warrior’s” latest season drew over two million viewers, solidifying the sport’s entertainment appeal. But behind the TV spectacle lies a rapidly expanding athletic community that extends far beyond the television.
Raising the bar
“American Ninja Warrior” veteran Joe Moravsky has won the title of “Last Ninja Standing” twice and has become a crowd favorite, earning the nickname “The Weatherman” for his day job as a meteorologist. But his entry into the sport was surprisingly simple.
“I saw it on TV. It looked easy. I wanted to try it,” Moravsky said.
That straightforward appeal has evolved into something far more complex. The newest season introduced a head-to-head racing format, replacing the traditional four-stage Vegas finals that defined earlier years. The obstacles themselves have transformed from intuitive challenges into strategic puzzles.
“There was no thinking about how the obstacle worked. It was obvious,” Moravsky said. “Now it’s like, how does this obstacle work? What’s the best way to do it? The obstacles are a lot harder.”
Today, hundreds of ninja gyms operate nationwide, from local independent facilities to major franchises.
Organizations like the World Ninja League and USA Ninja Association now govern the sport, hosting national competitions and providing structured training for athletes hoping to make it onto the show. These gyms have become breeding grounds for the next generation of competitors.
The sport revolves around five core obstacle types: moving with obstacles, campusing movements, climbing, generating swing, and foot dexterity. Classic challenges like the warped wall, salmon ladder, and quintuple steps have become so iconic that even non-participants recognize the terminology.
Small ninjas, big dreams
Regan Fletcher owns Ninja Republic, a San Mateo gym that attracts everyone from young children to adults. With obstacles designed for all skill levels, it’s a place where anyone can discover their love for the sport.
“We’re trying to provide a place for anyone who wants to move their body in a way that is different from any other type of sport, gym, or club,” Fletcher said.
What particularly draws young athletes is ninja’s demand for explosive power, agility, and creativity, qualities that favor youthful energy over pure strength. Many gyms now offer specialized classes and competitions for kids and teens, recognizing that this demographic often excels at the sport’s unique movement patterns.
When “American Ninja Warrior” lowered its age limit to 15 in 2023, a new generation of teenage athletes flooded the course. Among them was Talan Yorn, a 17-year-old Sacramento competitor who appeared on the most recent season.
“For the teenagers, we have the advantage when it comes to our bodies moving differently, and we’ve picked up a lot of new skills because we have more time to train,” Yorn said.
The youth takeover extends to the big stage as well. Recent seasons of “American Ninja Warrior” have seen an influx of teenage competitors, with the most recent winner claiming the title at just 19 years old.
“That’s kind of the biggest change with the sport – the youth, right? There are so many more talented people, and they’re all so young. They’re so good,” Moravsky said.
With younger athletes comes a crucial teaching opportunity: learning to handle failure. The obstacles that define ninja warrior guarantee falls, experiences that build resilience. According to the Child Mind Institute, not learning to tolerate failure leaves kids vulnerable to anxiety when setbacks inevitably occur.
“There’s a lot of parallels between ninja and real life, one of which is learning about yourself through failure,” Moravsky said.
Fletcher embraces this philosophy at Ninja Republic, making failure part of the experience from day one.
“One of the things that we tell everyone that comes into the gym is that we promise that they will fall, and they promise that they will get up,” Fletcher said.
More than just competition
For many participants, ninja represents more than athletic training; it’s a tight-knit community that brings together people from diverse backgrounds to tackle seemingly impossible courses.
“One of the things that ninja athletes often talk about is that they’re not competing against each other, they’re competing against a course,” Fletcher said.
This philosophy shapes the sport’s culture, even as competition intensifies. Ninja is inherently an individual sport with no teams, and the new racing format has amplified the competitive drive. Yet the camaraderie built off the course remains central to the experience.
“I’d say 99% of the people you meet are incredible and very supportive, and that’s what makes ninja so great,” Moravsky said.
For Moravsky, that supportive community is why he keeps returning. Even at 36, he competes for a reason deeper than personal glory. He competes for an audience who can’t, people facing their own impossible obstacles far beyond any warped wall.
“I’ve met some amazing people through my life, some who are no longer here with us,” Moravsky said. “But before they passed, they made sure to tell me that it’s because of me they’re still fighting the struggle they’re fighting.”
That same spirit of competing for others drives Yorn. While conquering obstacles on “American Ninja Warrior,” he was also battling Lyme disease, a sickness that many don’t understand. For him, competing meant more than chasing a buzzer; it meant using his platform to raise awareness.
“No matter what happens, I’m bringing more awareness to Lyme disease,” Yorn said. “Whether I fall on the first obstacle or get a buzzer, I’m giving other people like me hope.”
His appearance has inspired kids facing their own battles with Lyme disease, showing them that chronic illness doesn’t have to mean sitting on the sidelines. Through partnerships with organizations like the Center for Lyme Action and the LymeLight Foundation, he’s turned his platform into advocacy.
“Now that I’ve been able to achieve my goals and my dreams, I feel like I’ve shown other people that they can do the same,” Yorn said.
With ninja set to debut in the 2028 LA Olympics, this fantastical sport is set to become very real on the world’s biggest athletic stage. Whether it’s a 6-year-old conquering their first warped wall or a veteran hitting that final buzzer, the sport has become far more than just entertainment. It’s a testament to the power of always getting back up.
“Believing in yourself is such a huge part of this, especially in ninja,” Moravsky said.
