Train with the Best. Feel the Energy. See the Change.

At RedZone Athletic, fitness is personal—even in a group setting. We built our gym in Windsor, Colorado to bring the energy of a team workout together with the focus of one-on-one training. Every class challenges you to push harder, move smarter, and stay consistent. Whether you’re new to fitness or looking to reach new goals, our coaches meet you where you are and help you get stronger every week.

Local Coaches. Real Passion. Proven Results.

Owners Greg Osborne and Suzannah Mattson lead a team of passionate coaches who believe fitness should be fun, focused, and judgment-free.
Their goal is simple: help every member improve physically and mentally while building a community that feels like family.

Each coach brings unique experience in strength training, cardio, plyometrics, and functional movement, guiding you through workouts that are both challenging and achievable.

You’ll never feel lost in a crowd—our trainers are always watching your form, helping you modify moves, and keeping you motivated.

Our classes are catered to those looking to push their limits!

But if you have restrictions, this is a great place for you, too. We can watch your heart rate closely and modify the workouts based on your individual needs, helping you maximize caloric output. RedZone is NOCO’s first group workout with the feel of a personal trainer.
