HOLOLIFE VIKING ACADEMY - RETREAT EXPERIENCE
Coupon Code TATEKI
Summary & Key Takeaways
The HOLOLIFE VIKING ACADEMY was an immersive retreat at Viikingite Küla, a reconstructed Viking village in the forests of Estonia.
The Vikings' resilience was hormesis in practice—growing stronger from environmental stress, even using adaptogens like Roseroot (Rhodiola rosea).
Days ran on action, not lectures: cold river plunges into a smoke sauna, corrective-exercise sessions I led, upgraded beverages with Teemu Arina, axe throwing, and fireside connection.
Voluntary hardship builds the strength to handle involuntary hardship. That's the essence of becoming a Resilient Being.
Why do we look to the past to build the future of human potential?
As a fighter, entrepreneur, and biohacker, I've spent my life understanding the limits of human performance and pushing past them. We tend to look to cutting-edge tech and complex data for answers. But I've found some of the deepest secrets to resilience aren't new discoveries. They're ancient wisdom, waiting to be reclaimed.
That was the core of the HOLOLIFE VIKING ACADEMY, an immersive retreat we recently hosted. We didn't want to talk about resilience. We wanted to forge it in the flesh, with the timeless tools of our ancestors. We gathered a tribe of modern warriors—entrepreneurs, leaders, wellness seekers—and stepped back in time at the incredible Viikingite Küla, a reconstructed Viking village in the forests of Estonia. The goal: strip away the noise of modern life and rediscover the primal strength in all of us.
The Viking Spirit: More Than Myth
The Vikings have a fearsome reputation, but their story runs deeper than warriors and raiders. They were master navigators, explorers, and above all, survivors. Thriving in the harsh climates of the North, their resilience wasn't a mindset. It was a biological necessity. Their lives were constant practice of what we now call hormesis—adapting and growing stronger from environmental stress.
From the sagas, we know they mastered their environment. They built shelters that held against brutal winters, crossed vast oceans by reading the sun and stars, and understood the power of nature. They even used adaptogenic herbs like Roseroot (Rhodiola rosea) to boost strength and endurance. That deep connection to the natural world and their adaptability is what inspired the Viking Academy. They didn't just survive. They thrived.
The Experience: Fire, Ice, and Iron
Stepping into the Viikingite Küla is like entering another world. Surrounded by dense forest and the slow flow of the river, the village is a living piece of a bygone era. Woodsmoke hangs in the air, and the solid timber of the longhouse stands against the elements. This was our classroom and our training ground.
Our days weren't lectures. They were action. We lived the core of the Hololife philosophy—integrating physical, mental, and social wellbeing through direct experience.
Primal Stressors: We plunged into the icy river, bodies electric with the shock of the cold. Not just a challenge—a deliberate act of hormesis, activating cold-shock proteins and training the autonomic nervous system to stay calm under pressure. Then we retreated to the primal heat of a traditional Estonian smoke sauna, sweating out toxins and pushing our thermal limits. This hot-cold cycle is one of the most powerful biohacks for building cellular resilience.
Primal Movement & Corrective Strategy: As a fighter, I know raw strength has to be balanced with smart movement. I led sessions on corrective exercises to counter modern sedentary life. We worked on functional mobility, waking up dormant muscle groups, and building the physical integrity that supports both explosive power and everyday vitality. This is where ancient strength meets modern biomechanics.
Ancient Rituals, Modern Upgrades: Teemu Arina guided us through the art of the upgraded beverage. We explored how ancient rituals—coffee and tea—can be enhanced with modern knowledge of nootropics and nutrients to boost focus and energy. We also did Viking-inspired skill training, like axe throwing, which teaches intense focus and precision.
Primal Connection: In the evenings, we gathered in the longhouse around a crackling fire. We shared stories like a true Viking clan. This part is crucial. Resilience isn't just individual. It's strengthened by the tribe around you. In a world of digital isolation, that shared experience of struggle and triumph was maybe the most powerful part of all.
Forging the Modern Viking
The HOLOLIFE VIKING ACADEMY was never historical reenactment. It was about pulling the timeless principles of our ancestors into the challenges of the 21st century. The constant notifications, the endless workdays, the mental and environmental stress of modern life—these are our harsh winters and uncharted seas.
By choosing hardship, we build the strength to withstand the hardship we don't choose. By learning to be comfortable in discomfort, we expand what we can handle. That's the essence of becoming a Resilient Being.
The fires of the Viking Village may have dimmed for now, but the embers of resilience we forged there glow in every participant. This was a reminder that the strength we're after is already coded into our DNA. We just need to remember how to unlock it.
The saga continues.

Fought as a UFC fighter. Researches as a biohacker. And now, sat behind the mic on French combat sports media. During a trip to Nice for the Hololife Summit Côte d'Azur 2026, Tateki Matsuda appeared on JAB Life's "Ground & Talk" — the French-language MMA platform co-hosted by Boxing Squad head coach Aldric Cassata and former RMC Sport journalist Alexandre Herbinet. Sharing the episode with UFC fighter Axel Sola, fresh off a Fight of the Night at UFC London, Tateki discussed his career in the Octagon, the evolution of Japanese MMA, and his mission to bridge combat sports and sports science at the international level.
