Who he is

Not easy to place
in one category.
That is intentional.

He was not handed anything. No connections. No wealthy background. No safety net. Only the kind of stubbornness that turns setbacks into strategy — and silence into momentum.

Growing up, he studied the stories of people who built themselves. Bruce Lee. Jackie Chan. Jean-Claude Van Damme. Sylvester Stallone. Not for the fame. For what was behind it — the invisible years, the thousand failures before the one moment the world remembers.

The medal is only the last second of a very long story. Everything before it — that is where character is built.

Guinness World Record setter. Author of 512 pages. Founder. Experimenter. A multifunctional person in a world that prefers people to stay in one lane. He never learned how.

"My victories are known by many.
My losses — only by a few."— Aleksei Mirko
Chess — the school that shaped everything

He started at 7.
The club was 500 metres
from his front door.

No internet. No tutorials. Just a board, a clock, and a coach who trained children for free — because for him, sport was a calling. Not a business. That coach is no longer here. But what he gave lives on in everything Aleksei does.

At 13, he played in the selection tournament for the World and European Championships — competing inside Latvia for a place on the national team.

He drew his match. Not a loss on paper. But he knew. He had the position. He hesitated. He played safe. That moment never left him.

Chess and combat sports share the same DNA. In a fight, if you notice a weakness — a chess player does not rush. They redirect. They create comfort. And then — precisely, calmly — they strike exactly where they always planned.

"All mistakes are made at speed and in emotion.

Chess taught me to slow down before the moment that matters most — because the position that looks safe is often the one that costs you everything."— Aleksei Mirko
"His gift was not trophies.
His gift was the way he made us think.
I still carry that."— Aleksei Mirko, on his coach

Sport — a life spent in motion

Team captain across multiple sports.
Represented his school
and his city.

Not always the most talented in the room — but always the one who understood what it means to carry people forward. He led teams across different disciplines, different arenas, different seasons. Each one taught him something the previous one could not.

"An athlete earns their living from sport. I am a fitness enthusiast. Someone who cannot stop moving. That is the honest version."

01
Judo
The beginning. Discipline, respect, and the understanding that how you fall matters as much as how you rise.
02
Chess
Selection tournament at 13 — competing inside Latvia for the World and European Championships. Strategic thinking that shaped everything.
03
Athletics
Speed. Endurance. The discipline of showing up when no one is watching.
04
Football
Team leadership. Reading situations before they unfold. Bringing people with you.
05
Floorball
Fast and tactical. Where speed of thought matters more than speed of foot.
06
Combat Sports
Muay Thai. MMA. Brazilian jiu-jitsu. Grappling. Where chess thinking meets physical consequence.

Guinness World Record

A childhood dream.
Under a month to prepare.
One perfect minute.

In 2018 Aleksei Mirko set a Guinness World Record in London — 23 one-handed chest-to-ground burpees in one minute.

When he was a child, watching Guinness World Records on television in a small town with no internet, that book felt like the most serious achievement imaginable. He prepared in under a month.

The record stood for over a year and a half. It has since been broken. That is how records work. What cannot be undone is the fact that it happened.

"Officially Amazing.
12 May 2018. London, UK."— Guinness World Records Certificate
The experimenter

He did not read
about transformation.
He lived it. Repeatedly.

Multiple body transformations. Deliberately. Different nutrition plans. Different training approaches. Different cities, schedules, life circumstances — because the only honest laboratory is your own body.

He intentionally gained weight. Stopped training. Let the psychology of falling off happen the way it happens to everyone — and then came back. Not to prove a point. To understand from the inside what millions of people experience every day.

Because copying someone else's method does not mean it will work for you. You need your own compass. That takes knowledge, experience, and the honesty to admit that most of what you read online was not written for your body.

"Theory without practice is dead. Practice without theory is blind."— A principle Aleksei Mirko lives by

Things Aleksei Mirko believes

Four ideas.
No decoration.
Just the truth.

01
"The people who doubt you most
are often the ones closest to you.

That is not cruelty.
That is fear —
wearing the mask of concern.

If you have a dream and you are backing it
with knowledge — not just ambition —
you owe no one an explanation.
Move anyway."
— Aleksei Mirko
02
"I would rather give everything
and fail publicly
than give fifty percent
and wonder quietly.

Do not complain about losing
to someone who wanted it more than you.

For you it was a hobby.
For them — it was everything.

That is not unfair. That is honest."
— Aleksei Mirko
03
"Sleep matters. Recovery matters.

But years move faster
than most people realise.

Think about your childhood.
Now look at where you are.

Time does not wait
for the right moment.
Neither should you."
— Aleksei Mirko
04
"People say beautiful things
at funerals.

I believe those words
should be spoken
while someone is still here.

Build something.
Leave something.
Say what matters — now.
Not later."
— Aleksei Mirko
He started with nothing.
Not nothing as a figure of speech.
Nothing as a fact.

No wealthy parents.
No ready-made path.
No safety net.

He filmed a feature film. Alone.
No budget. No sponsors.
He built brands from nothing.
He wrote 512 pages nobody asked him to write.

When I was 18
I thought I knew everything.

At 35 — I know I know nothing.
At 100 — I will know even less.

Perhaps that is called wisdom.
The timeline

A life built
in stages.

Age 7
Chess — 500 metres from home
A coach who trained for free. A club before the internet existed. Strategic thinking that shaped every sport, every decision, and every business that followed. The coach is no longer here. The lessons never left.
Early
Sport — multiple disciplines
Judo. Athletics. Football. Floorball. Combat sports — Muay Thai, MMA, Brazilian jiu-jitsu, grappling. Team captain across multiple sports, representing his school and city. A small town. No internet. One direction — forward.
Age 13
Chess selection — competing inside Latvia
Selection tournament for the World and European Championships, competing within Latvia. He drew his match. Not a loss on paper — but he knew. The position was his. He hesitated. That moment never left him.
2014
FitZone Clinic — the plan that almost happened
A vision for a fitness clinic. A business plan. The wrong moment. The idea never died. It is still in progress.
2018

Mirko

"My victories are known by many.
My losses — only by a few."
— Aleksei Mirko
Nobody sees the hours before the result. Nobody sees what it costs. Aleksei Mirko built himself — in public and in silence — across three decades of sport, discipline, failure, and refusal to stop.

"If you believe in what you are doing — ignore the noise. Move forward. But bring knowledge with you. Wanting is not enough. It never was."
