The Story Behind Fenix Fitness

I Lost 55 lbs.
That's Why I Do This.

I wasn't born a personal trainer. I was an overweight teenager who didn't know where to start — until someone showed up and changed everything. This is that story, and why it drives every session I coach.

Where It Started

I Know Exactly
Where You Are.

At 16, I found out I weighed 200 pounds. I was embarrassed, frustrated, and had zero idea how to fix it. Stepping into a gym felt intimidating. Eating right felt impossible. And working out alone? I had no clue what I was doing.

So I hired a personal trainer. That single decision changed the entire course of my life. In total I lost 55 pounds, 28% body fat, and over 31 inches from my body. But the physical change wasn't even the biggest part — the confidence, the energy, the way I carried myself, the way I felt every single morning. That was the real transformation.

I remember thinking: everyone deserves access to this. Not just people who can afford a fancy gym. Not just people who already know what they're doing. Everyone. That's what Fenix Fitness is. It's the thing that changed my life — brought directly to yours.

How I Coach

Three Principles I Build
Every Session Around

1

Convenience Can't Be The Excuse

The number one reason people skip the gym is convenience. So I eliminated it. I come to your home — your living room, your garage, your backyard — with everything we need. There's no commute to talk yourself out of, no parking lot to dread. When I show up at your door, the only thing left to do is work.

2

Accountability Runs Both Ways

When I'm scheduled to be at your house, you're not going to bail — and neither am I. That dynamic of mutual commitment is more powerful than any program design. I track your progress, follow up between sessions, and show up every single time with the same intensity I'd want from a trainer if I were in your shoes.

3

The Body Follows The Mind

I've never had a client fail because their body couldn't do it. The ones who struggle are fighting something mental — doubt, stress, old habits, fear. So we work on both. Mindset, stress management, and sustainable habits are built into every client relationship, not offered as an add-on.

In-Home vs. The Gym

Why Your Home Gets You
Better Results

This isn't about convenience. It's about what actually produces results.

The Gym Experience

Split attention Your trainer is glancing at their phone, greeting other members, and watching the clock.
Ego and intimidation Crowded weight rooms create pressure to perform — which leads to bad form and injury.
Generic programs Group classes and gym trainers run the same program for everyone. Your body isn't everyone's body.
The drive as an excuse On a bad day, the commute is all you need to talk yourself out of going.

The Fenix Experience

100% of my focus Every minute of every session, I'm watching your form, reading your energy, and adjusting in real time.
Zero judgment It's just us. No one watching, no one comparing. You can be exactly where you are without embarrassment.
Built for your body Every program I design starts from scratch around your goals, your limitations, and your lifestyle.
Your door is the gym When the session is at your house, the only obstacle is opening the front door. That's a low bar.
