More Than a Gym.
A Community.
At SUT CrossFit, we believe fitness is about more than working out, it’s about becoming stronger, more confident, and the best version of yourself.
We’re a welcoming community built around functional fitness, dedicated coaching, and people who genuinely want to see each other succeed. Whether you’re new to fitness or looking to take your performance to the next level, you’ll find a place here.
Our coaches help you move well, build strength, challenge yourself, and reach goals you may not have thought possible. Our members bring the encouragement and accountability that make SUT CrossFit feel like more than a gym.
Formerly Highlands Ranch CrossFit and Redstone CrossFit, we became SUT CrossFit in 2024 to reflect who we are and what we’re building: a community focused on strength, growth, and showing up for one another.
Show up. Work hard. Have fun. Find your people.

williams
Coach
CF-L1 Trainer, USAW Level 1 Certified Coach
Whether you're working toward your first push-up, learning a new lift, or chasing a new one-rep max, Aaron loves helping people discover what they're capable of. As a CrossFit and USA Weightlifting Level 1 coach, he brings a thoughtful, encouraging approach to every class. Since starting his coaching journey in 2021, he's found the most rewarding part isn't just seeing someone lift heavier, but watching them accomplish goals that make a real difference in their everyday lives. Aaron believes progress looks different for everyone, and he'll be there to help you celebrate every step along the way.
When he's not coaching or training, you'll likely find Aaron ballroom dancing with his wife, Alex, or out walking their two greyhounds. Turns out, he's got some pretty good footwork both inside and outside the gym!
