Flatirons Performance Center

Flatirons CrossFit was the first CrossFit gym in Boulder and established the Boulder CrossFit scene. In 2007 CrossFit was nearly in its infancy. With a vision to deliver world class fitness to the athletic Boulder Community, Flatirons CrossFit set up shop on Boulder's east side.

Over the years we have worked with individuals from all walks of life wanting to change and challenge their fitness. The Boulder CrossFit community has grown tremendously over the years and Flatirons CrossFit is proud to have been here from the start to help it grow.
