Rocky Mountain Self Defense & Fitness strives to be a family-friendly training facility.

We have highly skilled and competent coaches who care about their students. We don’t care about being the biggest gym in town or about putting trophies on the wall. We care about the personal success of each member of our entire gym.

Head Coach John Hallett has over 21+ years of Krav Maga training & instruction. Jenny Jaeger-Hallett has over 15 years as a Crossfit & functional fitness training & coaching


We started out as a Krav Maga gym in Castle Rock, Colorado November 2005 with the focus on giving the community a practical place to train in self-defense. We are not another Martial Arts school or Sport/ MMA gym. We are about real-life training. There are no rules when someone attacks you or your family, Krav Maga is the answer to no rules fighting.

In 2008 we added Crossfit to the lineup. We saw Crossfit as a very complimentary strength & conditioning program to Krav Maga. Crossfit and Krav Maga share many similar philosophies: practical, anyone can do it (scaleable for all abilities, easy to get started, functional, no-nonsense approach), always pushing your limits. We knew it would benefit our existing members as well as bring it new members interested in functional fitness program.

ProjectFit Was added as RMSDF official fitness program in 2019. Over the last few years, we wanted to separate ourselves from other Crossfit gyms. We felt we had different goals than most Crossfit gyms and wanted the public to judge our program as it’s own brand of functional fitness.

The entire coaching staff at Rocky Mountain Self Defense & Fitness are focused on practical training. We do not believe that there are any quick fixes to get in shape. Nor do believe any of the programs we offer are “fad” workouts. We are about training for LIFE!

We are Not a Globo Gym. No Mirrors nothing fancy just real Training with real results.

We are not an MMA or Martial Arts school offering self-defense on the side. Sport and training for belts paid for not earned are not what we are about.
