The Man Behind the Mats
Details that
decide matches.
At eighteen I weighed sixty kilos and the guys at school laughed at me. I spent seven years grinding in the gym and got up to ninety. Then I asked myself — what am I going to do with it? In 2011 I walked into Tiger Gym in Prague-Řepy for the first time, and after one MMA session I knew strength alone gets you nowhere in grappling. I started doing jiu-jitsu.
My name is Daniel Holý. On the mats I'm Ragnar. I got my black belt from Fernando Araujo at Jungle BJJ Praha — the gym where I train next to Yakuza and Honza Vlasák, guys who win world-level tournaments. From the IBJJF European Championships I have four silvers and a bronze — three in no-gi, one in the gi (Master 2 division). In the 2024 no-gi black belt final I lost because my knee gave out — a year off versus a few weeks for an ankle is why I tapped.
I'm a guard player. Because I was always heavier and stronger than most guys on the mat, I learned to fight from the bottom — sit down, let the opponent attack from the top and wrap him up from guard. Heel hooks are banned in IBJJF Masters, so I built my game around toe holds and the details that work inside the rules, not outside them.
I prepared Karlos Vémola for his rematch with Attila Végh — the half-guard passing he finished with an arm triangle, we drilled together. I coach Nik Stedis, an MMA fighter. On Instagram I teach without words: a short clip, music, clean technique. Over half a million people from around the world follow me.
Ragnar Academy is what I wish I'd had fifteen years ago. No marketing fluff. Just the details that decide it when you're facing someone who wants to beat you.

Specialization
Leg Lock System
Heel Hook
Inside and outside heel hooks from saddle, 50/50 and outside ashi garami. The highest-percentage finish in modern no-gi grappling.
Toe Hold
IBJJF-legal at brown belt and above. Devastating as a secondary attack when combined with knee bar threats from ashi garami.
Knee Bar
Entries from top, bottom, and transitions. One of the most underrated submissions in modern grappling.
Saddle / Honeyhole
The control position that unlocks the entire leg lock game. Master this position first — everything else flows from here.
50/50 Guard
Offensive 50/50 with heel hook and ankle lock attacks. Not a stalling position — a finishing position.
Outside Ashi
The entry point to the entire leg lock system. Single leg X to outside ashi garami — from guard pull to heel hook finish.
Questions
FAQ
Ragnar Academy is my online BJJ instruction — no-gi grappling and leg locks. The paid videos run as a Patreon membership; this site is the hub: glossary, blog, interview and membership info. It's not a random pile of clips — every video is a whole technique: entry, control, finish and the most common mistakes.
Because random content won't teach you a system. YouTube gives you techniques. Here you get context — why this position leads to this submission, how to enter it from three different situations and what to do when things go wrong. The Instagram reels are a taste; the membership is the whole technique, the way I teach it at seminars.
Through Patreon (patreon.com/ragnaracademy) — in your browser or the Patreon mobile app. No sign-up on this site; you manage and cancel your membership directly on Patreon.
Depends how long you've been training. If you've been on the mats at least 6 months and know the basic positions (guard, side control, mount), the content will make sense right away. Complete newcomers should start with classes at a gym — without live sparring, online technique content has no real effect.
Two hours a week minimum: one for the video (watch + notes), one for drilling at training. The more you apply it live, the faster it sticks. It's not about collecting videos — it's about what you take home from training.
Part of the content (solo drilling, movement patterns, breakdowns) works without a partner. But honestly — grappling without live sparring is like learning to swim on dry land. If you don't have a gym, use the videos as a benchmark for choosing one.
The whole existing library the moment you join — 8 full-length instructionals on opening day (the whole technique, not a reel) — plus new videos on an ongoing basis for as long as you're a member. I'll confirm the pace of new videos at launch — I don't promise anything I can't keep.
$9.90 a month — one tier, monthly billing through Patreon. Patreon shows you the amount in your currency before you confirm. Newsletter subscribers hear the opening date first.
Primarily intermediate to advanced grapplers — blue belts and up who already understand the basic positions. The leg lock system needs some fundamentals. If you've trained regularly for at least 6 months, you'll benefit right away.
The videos are recorded in Czech. Subtitles are in the works — I'll announce which languages are available at launch. BJJ technique names are in English anyway.
The Patreon membership opens in autumn 2026. I'll announce the exact date in the newsletter and on Instagram — better later and complete than early and half-empty.
Yes. The Patreon membership renews monthly and you can cancel anytime directly on Patreon, no fees. Access stays until the end of the paid period.
Payments are processed by Patreon. I'll list the price in USD; what Patreon charges in your currency is shown before you confirm.
