Breathe. Take Control. Win.

Nice to meet you. I'm Mack Nenson, and I’m passionate about martial arts.

I’ve practiced Muay Thai since I was a kid, even competing for a short time at a semi-professional level.

No matter the problem, a couple of hours at the gym were enough to clear my head and reset.

At 29, my partner and I decided to move in together and settle in the city. Our lifestyle changed drastically. The rhythm of the city slowly consumed us.

Trying to meet the expectations of bosses, coworkers, and everything around us started to drain our energy and our patience.

Suddenly, training alone wasn’t enough to help me find my way anymore.

The Turning Point

I began to feel a constant sense of dissatisfaction. Sometimes it felt like sadness. Other times, like anxiety about the future.

I needed a solution, I had never felt that way before. That’s when I realized it was time to find something new. Something that could truly help.

I started practicing breathing exercises I found on Instagram, TikTok and YouTube. I dove deeper. For years, I studied breathing techniques from yoga and meditation. They eventually became part of my training routine and helped me reclaim the well-being I had been missing.

 Breath training gave me more energy, more focus, more confidence.

Why I Created Eldorio

After years of practice, breath training had become part of my everyday life. That simple habit had a positive impact on everything I did.
And I realized something important: all the people whose expectations I had tried so hard to meet were living just like me. Different lives, same daily emotions.

From that vision, Eldorio was born.

Eldorio applies resistance to your exhalation that’s all it takes to create the effects of both a yoga session and a cardio workout in one single device.

 Improving your breathing efficiency increases oxygenation in your blood, triggering undeniable physiological benefits: more energy, better cardiovascular endurance, reduced muscle tension, and clearer mental focus.

Breathe better, sleep better, stress less, perform stronger.
Breath control is life control.

This brand was born out of a simple but powerful belief:
Any goal in life can be reached with calm, clarity, and control; even when the world throws stress your way.

Your breath is the key.
And we’re here to give you the tool to unlock it.
Because when you breathe better, you live better.
