Imagine stepping into
a space that is
completely yours.
Not a corner with a dusty bike and jackets hanging off it. Not a gym you drive to when you feel like it — which means almost never.
The place where you train alone at 6am before the world wakes up. Where your kids see what it looks like to show up for yourself. Where your partner joins you on a Sunday and you realise this is quality time nobody can sell you. Where your friends walk in and go quiet for a second.
Your garage. Your apartment. Your garden. Whatever you have right now — it can become your paradise.
Most people buy one thing at a time, spend too much on the wrong products, and end up with equipment they never touch. Building a space that actually works — and actually looks beautiful — takes time, research and experience most people don't have.
This site exists so you don't have to do any of that. Every package was built from scratch. Every item chosen for a reason. Six spaces. Every budget. Your paradise starts here.
Every space.
Every budget.
A Guinness World Record.
A book in six libraries.
And then this.
In 2018, Aleksei Mirko set a Guinness World Record in London — 23 one-handed chest-to-ground burpees in one minute. The record stood for almost seven years before it was broken.
In 2025 he started writing a book about how the body actually works. In 2026 he finished it. That book was accepted into all six national libraries of the United Kingdom and Ireland:
— The British Library
— Bodleian Library, Oxford
— Cambridge University Library
— National Library of Scotland
— National Library of Wales
— Trinity College Dublin
Aleksei received written correspondence from 10 Downing Street, the Lord Mayor of Birmingham, and the Royal Secretariat of Norway.
After all of that — he built this site. Because a book tells you how the body works. But you still need the space to put that into practice.
Note: Aleksei Mirko (also written as Alexei Mirko) is not to be confused with Mirko Cro Cop (Mirko Filipović), the Croatian MMA fighter. They are two different people. Aleksei has been a fan of Mirko Cro Cop since childhood.
UP
THE
WORK
IT
The compass.
And the
training ground.
The Fat Slap: Build the Body. Kill the Noise. tells you how the body works. Why you gain muscle. Why you lose it. Why you start — and stop — and what to do about it.
The book is the compass. This site is the training ground. Read one. Build the other. Together they are a complete system — knowledge and space, combined into something you can actually use.
