The amazing Osso Brothers: From America’s Got Talent to acro worlds and beyond

The world’s best men’s acro pair hails from the U.S. – but for how long?

The Ossolodkov brothers, Seva (20) and Yaroslav (15), took acro to the masses when they appeared on America’s Got Talent during Season 20 last year. They were eliminated before the live shows, but within the sport, they are unstoppable.

The Kazakhstan-born brothers are undefeated as a pair in national and international competitions, dating back to 2022.

At the time, the Ossolodkovs – known as the Osso Brothers – weren’t yet U.S. citizens and could only compete domestically. They became citizens in 2023, and just a year later, became the first-ever men’s pair junior world champions.

“It was a really big moment, and I was very happy that we could be a part of it,” Seva told Gymnastics Now.

With acro worlds on a biennial schedule, Seva and Yaroslav have waited two years for their chance at the senior men’s pair titles, which could be their first and last.

Kazakhstan to California

The Ossolodkov family moved to Beaumont, California in mid-2016. The brothers have only gone back to their birth country once in the decade since then.

“I think we miss less of the buildings and the places, and more of family, because all of our family is still back in Kazakhstan,” Seva said.

Seva and Yaroslav’s parents – Konstantin and Natalya – opened Incentive – AGT in 2023. At Incentive, mom and dad coach the boys and they, along with younger brother Radomir, are active participants in the family business.

As a pair, it took time for Seva and Yaroslav to work well together.

“When you’re working with your sibling, there’s no boundaries to where you can’t yell at them or you can’t say mean stuff,” Seva said. “It’s your sibling. I mean, it’s very open.”

The transition period took a while – like a couple years – before the brothers really found their groove together. Now they can look at each other, and “we already know what we have to do.”

Seva complimented his parents on balancing the gym and home dynamic. Every now and then a bad practice bleeds into the home, making things tense, “but usually when we come home, it switches, and now our family is just eating dinner together and having fun, and then you get back to practice, and it’s coaches again.”

When they’re not training, they’re coaching. Fifteen-year-old Yaroslav leads two classes of boys under 7. Seva has his own team and is keen to grow Incentive’s recreational program.

“My goal is to improve the recreational program, not only in this gym but in general, because I feel like a lot of times kids come in, and of course some of them have fun, and that’s all they’re coming here for,” Seva said. “But a lot of times parents are not educated on this topic enough to understand how much time and commitment needs to be done to achieve the goals.”

Somehow, Seva also had the time in the past few years to earn his private pilot’s license.

On the clock

There has been a lot of talk about extended gymnastics careers in recent years, but no one can stave off puberty forever.

That’s the biggest challenge the brothers have faced this year, with Yaroslav going through a significant growth spurt.

“We started the season without being able to do pretty much any of our skills,” Seva said.

In 2025, their first senior season, things were easy. Yaroslav was still competing with a “junior body set” and Seva could fix most mistakes by just throwing harder.

This season has been much different. “Yaroslav is a man already and is as tall as my mom,” Seva said.

Now Seva can’t just throw harder – it’s more about technique.

“We had to change a lot, and then midway through the year, we managed to bring back a lot of the old skill sets,” Seva said. “I’m very happy for that, and it’s been a big year for us.”

The brothers won the 2026 World Cup Series title after winning all four of their World Cup appearances this season. They also won their second consecutive U.S. men’s pair title, topping the field in all four categories – combined, all-around, balance, and dynamic.

Incentive to evolve

There are three senior world titles up for grabs in Pesaro, Italy, this weekend, and the Ossolodkov’s qualified first in all three categories: balance, dynamic, and combined.

Kazakhstan’s pair is one of their top competitors, having qualified second in balance and combined and third in dynamic.

But what happens after Pesaro?

Yaroslav will continue to grow, and the next world championships aren’t until 2028. The next World Games is in 2029.

“We will decide after this competition if this will be our last competition or if we’re going to continue afterwards,” Seva said.

Incentive – AGT is a true family affair, and the gym takes a lot of time and responsibility.

“Right now, we’re leaning more toward the side of we have to do what’s better for our future, and we don’t know if that’s necessarily continuing with acro after this,” Seva continued.

They have a replacement already lined up though. Remember the youngest Ossolodkov – Radomir? He’s already on the national team with partner Martin Seredich.

“A lot of the skills that we lost, they already have, and it’s a very interesting moment to live in because it’s a literal replacement,” Seva said. “But not in a very bad way, in a very good way, and we will be rooting for them definitely next year.

“It doesn’t matter if we’ll compete with them or not compete. We’ll still be rooting for them because they’re the future.”

That future could also see Seva and Yaroslav join Radomir and Seredich in a men’s four together in a couple years.

“For Martin, we’ll have to change his last name too,” Seva joked. “So then it’s going to be four Ossolodkovs together.”

For the love of acro

The brothers hope that one day acrobatic meets will take place in front of packed stadiums, but for now, they’ve gotten a taste of what that would be like by performing at artistic Olympic Trials and competing on America’s Got Talent.

“I remember a moment [on AGT] we were doing one of our final skills,” Seva said. “He was on my head, and we were standing up. And then I saw people stand up as well and start cheering all behind the judges. And it was – it was just a wow wow moment.”

Acro is one of the lesser followed gymnastics disciplines, especially in the U.S. But even though they were born into acrobatics, it seems Seva and Yaroslav genuinely love their sport.

“I like presenting myself [and] competing,” Yaroslav said. “That’s very fun for me… And just inside the gym, it’s very fun. Most practices are very funny because you have a lot of friends here too.”

“To me, I think both disciplines, gymnastics and acro, they prepare you for any other sport in the future,” Seva said. “… And then personally, for me, right now, everything I have has been because of acrobatics. Like it’s been a central part of my life this whole time, and it’s like when you’re born, and then you grow up, and somebody asks you why you love your mom. You know, you just love it. You love her. You love your mom. You love your parents. You’ve grown up with them since the very beginning, and it’s the same thing for acro.”
