Daniel Holý: From Sixty Kilos
to a Black Belt

Chapter 01From sixty kilos to a black belt

Daniel Holý didn't start out as a talent. He started out as a skinny kid getting laughed at by his classmates. He spent seven years lifting weights to prove to himself and everyone else that he was worth something — and only then did he find grappling.

How did you actually get into jiu-jitsu?

I'd been lifting weights since I was around seventeen. At eighteen I weighed sixty kilos. The classic stuff — you're skinny, you're a stick figure. So I told myself, alright, I'll show you, I'm turning myself into a hundred-kilo beast. Seven years of grinding and I got to ninety. Then the lifting stopped doing it for me, so I went looking for somewhere to actually use that strength. In 2011, I walked into Tiger Gym in Řepy (Prague) for the first time — back then one of the biggest combat sports gyms in Prague. And that's where I started with MMA.

And how did MMA turn into jiu-jitsu?

MMA was breaking me. I had work meetings, I couldn't show up beat up. Jitsu was more comfortable for me — fewer strikes, more control. On top of that, in grappling I figured out fast that you can't get far on strength alone. You have to think. That's what hooked me.

Chapter 02Why I'm a guard player

In Brazilian jiu-jitsu there are two types of competitors: the aggressive top player who pressures the opponent down, and the guard player — someone who sits on his butt and lets the opponent attack from above so he can wrap him up from underneath. Daniel belongs to the second type — and the reason isn't aesthetic, it's purely practical.

What do you think matters most in jiu-jitsu?

Head, strength, and athleticism. In that order. Jitsu has hundreds of techniques and you have to actually understand them, not just copy them off a video. Only a small percentage of people who start jitsu ever make it to black belt. The rest drop out. Precisely because it's mentally hard — you have to spend years doing something where someone is constantly running you over.

And why guard, not aggressive top pressure?

Two reasons, both practical. First: my game is leg locks, and you enter ashi garami and the toe hold naturally from the bottom. If you want to lock someone up by the leg, guard is the logical starting position. The second reason is physics — I'm heavy. On top, the smaller guys at the gym just slip out and run away from me; from the bottom I control them better with weight and frames. In IBJJF Masters divisions, heel hooks are banned, so the toe hold is my main finish.

Chapter 03An engine that doesn't slow down

Daniel is open about the fact that what drives his performance isn't pure love of the sport. It's something harder, something old from his childhood — and that combination is what makes him a competitor who doesn't quit, even when he's throwing up with nerves before a match.

You mentioned that your head was always a problem. What did that mean in practice?

Up until two or three years ago I was throwing up before matches. The classic — stress, fear of losing, fear of letting down the people around you. Most of that pressure you build yourself. I decided to fight it precisely by signing up for the biggest tournaments, against the toughest opponents. That hardened me mentally.

Did anything besides exposure help?

Visualization. A few days before a competition I picture myself walking out, weighing in, what kind of opponents I'll have — I deliberately picture huge guys with cauliflower ears, the worst-case scenarios. The brain slowly preps itself for the fight, and reality usually ends up easier than what I painted in my head. At this year's Europe, in the semis, I was up against a guy who was ranked fourth in the world. I figured I had no chance. I tapped him in forty seconds.

Chapter 04How I taught Karlos to pass half guard

When Karlos Vémola (Czech MMA champion, Oktagon MMA headliner) was preparing for his rematch with Attila Végh (Slovak MMA champion, former Bellator Light Heavyweight champion), he kept driving over to train with Daniel at Jungle. One specific technique from those sparring sessions ended up showing in the fight that finished by arm triangle.

Who else do you work with besides Karlos?

I coach Niko Stedis, an MMA fighter. Otherwise I take my own classes at Jungle. The advantage of Jungle is that there are two to three hundred members and the people around me include guys like Yakuza or Honza Vlasák — guys who win world tournaments. Compared to Yakuza I'm small fry on the Czech jitsu scene; he's an absolute phenomenon. I don't really need to travel anywhere else, the rolls at Jungle are enough.

How hard is it to find quality sparring partners at your level in the Czech Republic?

There's a handful. The problem with the Czech grappling scene is ego — guys keep their gyms as bubbles, they rarely cross-train with each other. So when we travel to the big international tournaments, the country has over sixty black belts and there's usually three of us out there. Guys who want to grow have to step out of the comfort zone. There's no other way.

Chapter 05Instagram without words

More than half a million followers from all over the world — and Daniel never says a word in his reels. It's a deliberate strategy built on how the short-video algorithm works and how BJJ technique gets learned visually.

How is it that you're not well known in the Czech Republic but you are abroad?

The Czech Republic is a small pond. Jitsu here isn't mainstream the way MMA is. And my reels are captioned in English, no spoken word. The algorithm picks that up and it lands more in Brazil, the US, or the rest of Europe than at home.

What from your online stuff can a complete beginner actually use?

Not all the techniques are complicated. There's stuff you can grasp at first sight. The more advanced techniques are more for people who've been doing jitsu for a few years — they know the physiology, they know where the arteries are, where to push. Something I've adopted lately: I test everything before I film. I don't post anything that doesn't work. If it doesn't choke, doesn't break, or doesn't leverage, it doesn't go on the channel.

Chapter 06The 2024 final — knee or medal

Black belt debut. Final of the IBJJF European Championship. Daniel found himself in a situation where one second he was cranking a Brazilian's ankle and the next he heard the crunch in his own knee. The decision whether to keep going or tap came in a split second.

Why didn't the Brazilian tap when his ankle was popping?

Brazilians have ankles like rubber — popped, torn, used to it. I was focused on finishing him and I completely forgot about my own leg. He caught me with the same lock, except on me the rotation went into the knee. By the time it cracked, the match was over either way. The tap was just damage control before something worse — a year of knee rehab versus a few weeks for the ankle. That's not reason winning over ego, that's just bookkeeping after the fact.

Is it really hard to actually tap in that moment?

It's hard. Your head is screaming that you're winning, you're a second from a medal. I only tapped after it had already snapped — and that's exactly what I want to do better next time. Read the signals in the joint earlier, not after it pops. There are guys who let themselves get put to sleep in a choke because they're seconds from the end of the round and ahead on points — they nap, they wake up, they win. You bounce back from that physically. A torn knee ligament is a different story.

Chapter 07What Ragnar Academy is

After fifteen years on the mat, Daniel is opening an online academy. The stated philosophy is simple: no marketing fluff, no content for the sake of content. Just the things that decide a match.

Who is the academy for?

For people who are serious about getting better. I'm not aiming at the absolute beginner — that's what local clubs and coaches are for, all over the country. I'm aiming at competitors, advanced hobbyists, and coaches who are looking for the structure underneath my leg lock game. I want to show the geometry, the conditions, the control — not just the set-up and the finish. The guys who message me on Instagram long-term, that's exactly the audience.

How is it different from the online courses already out there?

I don't want to compare myself to anyone specific. I can only say what I'm putting in. Things that work for me at IBJJF tournaments — including the variations that exist because of the rule restrictions in Masters. Specific ashi garami transitions, toe hold details, guard traps. And I'll put in mindset material. The pre-match psychology, visualization, how to work with a loss. That's just as important as the technique.

What's the next competition goal?

Europe. Gold, finally. And then Las Vegas, the World Championship. That one would be sweet to grab.
