ABOUT
Marietta roberts
With more than 30 years of experience as a personal trainer and fitness instructor, I’ve had the privilege of guiding everyone from professional athletes and celebrities to aspiring Olympians toward their peak performance. My passion lies in unlocking each client’s unique potential, whether they’re stepping onto the world stage or simply stepping into their best life.
Originally from the beautiful island of Puerto Rico, I now call Colorado home, where the stunning mountain landscape continues to inspire my approach to fitness and wellness. My diverse background and extensive experience have taught me that every body is different, every goal is personal, and every victory—no matter how small—deserves celebration.
I believe fitness isn’t just about building muscle or losing weight; it’s about building confidence, resilience, and a deeper connection with yourself. Let’s work together to discover what your body is truly capable of achieving.
