Childhood should be filled with movement, adventure, and moments that make kids proud of themselves.

More Than a Ninja Gym
For 10 years, we've been creating a different kind of place for kids to move, learn, and grow.
From experienced, career-coaches and progressive skill development to a one-of-a-kind environment designed around adventure and play, everything at Warrior Playground has been built with intention.
Pioneers in Colorado Ninja
Warrior Playground was Colorado's first dedicated ninja gym and remains its longest continually operating ninja facility. Over the past decade, we've grown from a backyard training space into a 12,000-square-foot home for beginners, recreational athletes, and competitive ninjas alike.
Experience That Goes Beyond Ninja
Great athletes know how to do obstacles. Great coaches know how to teach them.
Our coaching team brings decades of professional experience in coaching, personal training, gymnastics, early childhood education, and child development—along with competitive experience on American Ninja Warrior and at the world level in ninja and obstacle course racing.
That depth of experience means we know how to meet kids where they are, challenge them appropriately, teach skills safely and progressively, and help them experience real success.
A Playground Built for Adventure
Warrior Playground doesn't look or feel like a typical gym—and that's intentional.
Natural wood obstacles, a treehouse, suspended bridge, tunnels, forests, mountains, and a giant hand-painted river mural transform the gym into a world kids want to explore.
Because when movement feels like play, kids want to keep moving.
Some of our favorite moments happen when a child looks toward the benches with the
biggest smile you've ever seen and shouts,
Those moments never get old.

“My son started out afraid to try almost everything. Now he's constantly asking us to watch what he can do.”
“We've tried every sport. This is the first activity she's begged to keep doing.”
“The coaches know exactly how to challenge kids without making them feel overwhelmed. We've watched our daughter grow so much.”
For ten years, Warrior Playground has been helping kids discover what they're capable of.
Thousands of children have climbed their first wall, conquered their first fear,
made lifelong friends, and celebrated victories big and small.
Some have gone on to compete nationally.
Others simply discovered a place where they felt confident, capable, and excited to move.
Every journey matters to us.
Thank you for making us part of your family's story.

The best coaches don't just teach skills.
They help kids believe in themselves.
They encourage.
They celebrate.
They challenge.
They notice when a child needs one more try, or one more high five.
Every member of our coaching team is committed to creating an
environment where every child feels seen,
supported, and excited to learn.
