Founder & Coach
Peter Schaale
Fitness changed my life — not just physically, but mentally. It gave me structure, confidence, and a way to grow through the tough times. As a former professional athlete, I learned early how powerful consistent training and discipline can be — but I also learned how easy it is to lose your way without the right support.
Now, I help others build a lifestyle that lasts: strong habits, purposeful training, and a mindset that holds up under pressure.
My approach is simple: real effort, real support, and consistency over everything.
Right now, I’m training for the Hyrox Pro Race in Dallas this November and planning to compete more frequently.
I’m on the journey too — pushing limits, staying curious, and showing up relentlessly.
Let’s get after it.

Co-Founder & Coach
Justyn Meilleur
Fitness isn’t a hobby for me — it’s survival. It’s how I deal with stress, anxiety, and everything life throws my way. For over 15 years, I’ve used training as my outlet — my way to stay grounded, focused, and sharp.
I don’t believe in shortcuts. I believe in showing up, putting in the work, and pushing past limits that most people back down from. Whether it’s dragging myself up punishing mountain trails, going to war with the weights, or pushing through a brutal boxing session — I’m always chasing that edge.
This site is built for people who want more. More grit. More growth. More fight. If you’re tired of watered-down workouts and empty motivation, you’re in the right place. This is about real training, real results, and digging deep to become something better.
Let’s get to work.

Co-Founder & Coach
Marcus Campanile
Fitness is more than a routine—it’s a tool for clarity, resilience, and growth. Through years in sport and personal development, I’ve learned that progress lives in the details and the discipline.
Driven by a passion for fitness and self-improvement, I bring years of athletic experience and a mindset rooted in consistency, grit, and growth. Small steps, done relentlessly, change everything.
I’m here to support the Relentless Theory community in building habits that last and pushing through life’s challenges—together.
