Meet the Founder
The method behind KouliWorld is not software. It is one coach, standing in the room, who trains the way he asks you to.
Welcome to the world. I’m Théo, a French personal trainer currently based in Cambodia, and I’ve spent my entire life preparing to build this platform.
Since my childhood, sport has been my oxygen. At just 5 years old, I was already skiing down the Pyrenees. Over the years, I became a serial practitioner of movement, testing my limits in everything from basketball and rugby to surfing and Kun Khmer.
I’ve always had an insatiable curiosity and a stubborn refusal to be average at anything I tried. I wanted to be good at everything. I would analyze video tutorials for hours, repeating movements until my technique was flawless and perfectly efficient.
Naturally, I fell in love with individual sports and martial arts — raised on Bruce Lee films and spending years mastering boxing — because I demanded absolute control over my own performance. I didn’t know it yet, but I was developing the mindset of a true hybrid athlete.
To back my passion with elite knowledge, I moved to the Caribbean to graduate in Sports Sciences and officially became a personal trainer.
KouliTrainz is the culmination of that lifetime of exploration. My mission here isn’t to make you a specialist who can only do one thing. I am here to teach you how to become completely polyvalent. Together, we will build a frame that possesses devastating strength, relentless endurance, and high-level skill.
Stop limiting your potential.
Let’s enter the arena and upgrade your standard.

Off the gym floor
Phnom Aural is the highest point in Cambodia at 1,813 metres. The training in this app is the training that gets you up things like it.
