CrossFit Thornton

We believe in pushing limits, digging deeper, and working harder. We believe the only thing between you and your next goal is you. 

Every program we design is measured against our philosophy. Every program will push your limits, keep you focused, and strengthen you. Whether you’re six or sixty, just starting out, or looking to compete, our programs are designed to keep you engaged while experiencing results.

We are a group of coaches who believe in quality over quantity. We specialize in program design and exceptional coaching. So that we can always provide you with the motivation and guidance you need and deserve, our classes average one coach for every ten athletes.


We want you to know that our goal is to level up your experience relative to any gym you've previously attended. We recognize that our athletes come to us with various fitness experiences. We're confident that no matter where you come from, you'll leave feeling like you achieved the perfect stimulus designed around every workout.

Our 5,400-square-foot facility is centrally located just 20 minutes from Denver, Boulder, Brighton, Arvada, and other major metropolitan areas. Whether you're local or just dropping in while traveling, we welcome you as a member of the CrossFit Thornton family. 

What Makes CrossFit Thornton Different?


Every one of our coaches is sold out on providing the best possible coaching experience.

"Champions are not molded out of clay; they are chiseled out of stone."

“Your body can stand almost anything. It’s your mind that you have to convince.”

“The only thing permanent is change.”

"Let's live a lifestyle where people look at you and think you're built different."

"Motivation is what gets you started. Habit is what keeps you going."

"Relationships aren't just something. They're everything."

“If you want something you've never had, you must be willing to do something you've never done.”
