Scott Carpenter
Scott Carpenter is the Founder and CEO of Underground Fitness, bringing more than 14 years of vision, leadership, and innovation to the fitness community in Phoenix. From the very beginning, Scott set out to create a space that was more than just a gym — a place where people of all ages and fitness levels could feel supported, challenged, and inspired to change their lives.
Under his leadership, Underground Fitness has grown into one of the top boutique training studios in Phoenix, recognized as a multi-year Neighborhood Favorite and celebrated for its personal, results-driven approach. Scott’s passion lies in building both people and community: guiding clients toward healthier, stronger versions of themselves while fostering a culture of accountability, care, and long-term success.
His mission is simple — to ensure that every client who walks through the door is met with expert guidance, genuine support, and the opportunity to achieve results that last a lifetime.
*"When I started Underground Fitness, my vision was simple: create a place where people felt truly supported in their fitness journey — not just another gym where you’re left to figure it out alone. I wanted to build a community where coaches listen, programs are personal, and results are real.
Fourteen years later, I’m proud to say that’s exactly what we’ve built. Every client who walks through our doors matters, and our team is dedicated to helping them succeed inside and outside the gym.
Thank you for trusting us with your goals. Underground Fitness exists because of the amazing people we serve, and I’m excited to see what we can achieve together."*
