About P3 Fitness
Power – Performance – Persistence
Why P3?
At P3, we train for more than fitness — we build POWER, elevate PERFORMANCE, and teach PERSISTENCE.
At the heart of why we started P3 is a simple dream — to help kids and families grow strong and stay active together. Between our two families and six sports-loving boys, we know just how important movement, teamwork, and confidence are both on and off the field.
Through our experience coaching young athletes, we've seen just how critical proper training is in helping kids avoid injuries while working toward their goals. We're passionate about creating an environment where hard work is celebrated, bodies are challenged, and minds are trained.
At the core of P3, our goal is to help build well-rounded athletes who develop strength, resilience, and confidence that carries far beyond sports. Based in Henderson, Nevada, we serve families across the Las Vegas Valley.

Every session is engineered to sharpen athletic performance — whether you're racing obstacles or dominating your sport.

We show up, do the work, and trust the process. Champions aren't born — they're forged through relentless persistence.
