…is the principal strength and conditioning program for many police academies and tactical operations teams, military special operations units, champion martial artists, and hundreds of other elite and professional athletes worldwide.

The CrossFit program is designed for universal scalability making it the perfect application for any committed individual regardless of experience. We’ve used our same routines for elderly individuals with heart disease and cage fighters one month out from televised bouts. We scale load and intensity; we don’t change programs.

Benefits of CrossFit:

  • Effective at burning a high number of calories in a short period of time.
  • Great cardiovascular conditioning
  • Increases joint mobility.
  • Increases your strength and functional fitness.
  • It is Fun!
  • Great place to make friends.

At Yellowstone CrossFit your health and safety are our priorities. We take an integrated approach to training and will help you meet your personal fitness goals.


Words cannot describe how the coaches and Yellowstone CF changed who I am. I first joined at the heaviest I have ever been in my life. The coaches never gave up on me, they are encouraging and never let me quit. I met my goal of running a half marathon and increased my self-confidence. With many inches, pounds, and pants sizes later, they still pushes me every WOD.
