Justin Collen: owner & Head Coach
"As a coach with a Master’s in Exercise Science and years of applied experience, I cut through the noise to deliver what actually works for you. I’ve built and grown gyms in New York and Texas before bringing that experience to Colorado. Now I’m bringing a long-time vision to life, building this performance facility in Woodland Park. My approach is shaped by both real-world results and my background as a collegiate football player and competitive strongman.
Every program is designed for longevity and peak performance, with intentional progression, ongoing assessment, and adjustments based on movement, readiness, and results. My approach to nutrition goes beyond calories and macros. While they matter, they’re just part of the picture. I focus on how food impacts your physiology to create sustainable, effective strategies tailored to you.
I’ve worked with a wide range of clients and competitive athletes and consistently delivered results by prioritizing strength and performance. Driving better body composition, conditioning, and overall well-being. Every program is built around your goals, with the right training elements to get you there."

"As a Performance Coach, my focus is on helping you build strength and improve performance through training and nutrition. Every program is built around your individual goals, with an emphasis on developing a strong foundation and supporting long-term success.
I’m especially passionate about helping active girls and women build strength, confidence, and learn how to train and fuel their bodies for performance. I hold additional certifications focused on training and nutrition for women, and use science-based strategies to guide my approach.
In addition, I’ve worked with high-level athletes and been closely involved in competitive sports, giving me a strong understanding of what it takes to perform at the next level."

"I am passionate about helping others achieve their fitness, health, and performance goals. With a background in collegiate rodeo and athletics, I understand the discipline required to perform at a high level and achieve results.
Along with personal training, my experience as a stretch practitioner has given me a strong understanding of mobility, muscle imbalances, and movement patterns that impact performance. I believe small adjustments can make a meaningful difference in how the body moves and performs.
My approach focuses on strength, mobility, and building habits that produce lasting results.
I look forward to coming alongside you and helping you achieve your goals every step of the way."
