AboutMe

From insecure teenager to engineer to fitness coach. How I learned to treat my body as a system.

The Beginning

I started because I
hated how I looked.

On my 16th birthday, I walked into a gym for the first time. I was chubby, insecure, and tired of feeling bad about my body. I didn't know what I was doing. I just knew I had to do something.

Social media wasn't big yet, so I learned from fitness magazines and trial and error. I tried everything. Machines, free weights, different splits. Most of it was probably wrong. But I showed up, and that was enough.

Within a year or two, the body issues were mostly fixed. But something interesting happened. I kept going. Not because I hated my body anymore, but because fitness had become the foundation for everything else in my life.

The Shift

I stopped trying to look strong.
I started trying to be strong.

The breakthrough came when I discovered calisthenics and street workouts. I watched these guys doing muscle ups and front levers, and I realized something: they looked incredible, but they weren't training for looks. They were training for capability.

I had it backwards. I was trying to sculpt muscles like a bodybuilder. They were just getting brutally strong at a handful of movements. The physique was a side effect.

I threw out my bodybuilding split. I focused on weighted pull ups, weighted dips, and heavy squats. Within six months, my body changed more than it had in three years of isolation work.

The Lesson
The Mistakes

I pushed too hard
and paid for it.

In the beginning, I got very impatient. I had the principles right but I ignored them. I pushed harder than my body could recover from. I wanted faster results.

I developed multiple injuries that I still manage to this day. It's been a brutal lesson in something I already knew intellectually: you cannot force adaptation. The body operates on its own timeline.

That experience changed how I think about training. I'm not just training for next summer. I'm training for 70. Every decision I make now has to serve both the short term and the long term.

The Philosophy

Engineer's mind.
Athlete's body.

I studied industrial engineering in Spain and control systems in Denmark. I worked on self driving trucks for Volvo. I built a software company. My brain is wired to think in systems.

The body is the most complex system I've ever worked with. It's not a simple machine where you put calories in and get muscles out. It's an adaptive system that responds to signals. Give it the right stimulus and recovery, and it transforms. Give it the wrong inputs, and it breaks down.

Everything I do now comes from that understanding. I don't chase trends. I don't follow influencers. I apply the same engineering logic that built my career to building my body. It works.

Why Now

Fitness changed my life.
My life changed fitness.

I've never made a dollar from fitness. My income comes from software. But I've spent 14 years learning how to train, how to eat, and how to recover. That knowledge deserves to be shared.

I'm building this brand because the fitness industry is broken. It's full of steroid users pretending to be natural. It's full of people selling shortcuts that don't work. And it's full of bad advice that optimizes for looking good in photos while destroying your joints and your health.

I want to be a different voice. An honest voice. Someone who has been doing this for almost half his life and can tell you what actually works when you don't have drugs and you're not planning to compete on a stage.
