Why Fitnetic is different
Most gyms hand you a program. Ruben builds one around you.
Big-box gyms and bootcamp apps give everyone the same plan and hope it sticks. Ruben does the opposite.
He starts with your body, your goals, and your starting point, then builds the training that actually gets you there. Chasing a PR, a comeback, or just feeling good in your own skin, it's the same coach meeting you exactly where you are.
And he's especially good with the people other coaches give up on.

You're never
just a number.
One-on-one or in a group class, Ruben coaches the person in front of him. He learns your body, adjusts on the fly, and pushes you exactly as hard as you should be. No more, no less.
Train at his San Diego studio, in a class with a crew that has your back, or from home over Zoom and FaceTime.
"The HIIT and kickboxing classes are intense and invigorating, and he tailors every session to your goals. Highly recommended."
Cristina T."He tailors every workout to me, always evolving, challenging, and fun. You leave with a real endorphin rush and a better mindset."

Your first step
It's just a conversation.
No commitment. No sales pitch. Ruben asks what happened, what hurts, and what you want back. You'll walk away knowing exactly what a plan would look like, even if you never sign up.
Start with a free consultation →"Do I need to already be in shape?"
No. That's the entire point. Ruben starts wherever you are today.
"I'm an athlete chasing real performance."
You're in the right place. He trains for speed, power, and your sport, not just general fitness.
"I'm coming back from an injury."
That's what he's known for. Every session adapts around it, not in spite of it.
Let's get you stronger.
A free consultation. No pressure, no commitment. Just an honest conversation about your goals and how to reach them.
