Trainers in Arvada

“As a veteran who has had to stop going due to service-connected disabilities, I can still say without a doubt that Arsenal is one of the best facilities I’ve ever been a member of. I particularly loved using their boxing classes—it was incredible for my memory, which is one of my disabilities. My speech therapist even noticed a significant improvement, which speaks volumes about the quality of the instruction and the workout.“

“INCREDIBLE! I highly recommend core progression because nowhere else has worked and I finally lost this impossible last 15lbs and my back and posture is 100% better. love you guys so much!!“

“Top notch studio and instructors. I've taken private and group classes with Katie and her team for over a year now. Great instruction and I always get the attention I need during class and private sessions. My back and neck pain has improved, and I highly suggest job visiting Katie and her team.“

“supportive coaches and high energy classes! I love being a part of this community and highly recommend to anybody looking to continue or start their fitness journey.“

“I began working with Amy several months ago as I started training for the Chicago Marathon in 2025. I hadn’t run in years, but from the very beginning Amy made me feel confident and comfortable that I could do this.

What sets Amy apart is that she doesn’t just hand you a plan. She takes the time to assess your individual needs—your strengths, weaknesses, and goals—and builds a program that helps improve muscle strength, flexibility, and running strategy. Her approach is thoughtful, personalized, and effective.

Beyond her expertise, Amy is incredibly kind, generous, and fun to work with. She motivates you in a way that makes the process enjoyable, even on the tough days. Without her guidance, there’s no way I’d be on track to run this marathon, and more importantly, to keep running beyond it.

I feel so lucky to have Amy as my coach, and I encourage anyone considering training for a race—or simply wanting to become a stronger, healthier runner—to work with her. She’s the best partner you could have on this journey.“

“I run and own a civil engineering firm in the area. I also travel train and plan professional beach volleyball. Sam is excellent and creates workouts/programs that cater to exactly what you need and he meets you where you are at. Super personable super expert.“
