OUR STORY
MODESTO DESERVED BETTER.
In 2017 Claudia looked at the gym landscape in Modesto and saw a gap. There were plenty of places to show up and go through the motions — but nowhere built specifically for people who wanted to train seriously. No real coaching. No real community. No real standards.
​
So she built it herself. From scratch. As a woman entering a male-dominated industry, she didn't just open a gym — she made a statement. That the best facility in Modesto would be built on expertise, community, and an uncompromising standard for what training should look like.
​
Seven years later Relentless Fitness is home to Modesto's most dedicated lifters, five certified personal trainers, and a growing community of people who refuse to settle for average.

WHAT WE STAND FOR
OUR MISSION
01
SERIOUS TRAINING FOR SERIOUS PEOPLE
Relentless exists for people who want to actually train — not just show up. We hold a higher standard because our members hold a higher standard of themselves.
02
Quality Coaching,
Accessible to All
Expert personal training shouldn't be reserved for the wealthy. We built a facility where world-class coaching is available to anyone willing to put in the work
03
A Community That Pushes You Forward
The people you train around matter. We've built a community of determined, ego-free lifters who make each other better — every single session.
04
Prove What's Possible
Claudia built this gym to prove what's possible when a woman leads with expertise, passion, and no regard for what "can't be done." That spirit runs through everything we do.
05
Old School Standards. New Generation Energy.
We believe in the fundamentals — barbells, hard work, progressive overload, and showing up. We pair that with modern coaching, programming, and a community built for the next generation of athletes.
06
Make Your Mark
Every member who walks through our doors is working toward something. Our job is to give them the tools, the coaching, and the environment to achieve it. Be relentless.
