Meet John Hallett and Jenny Jaeger of Rocky Mountain Self Defense & Fitness

Today we’d like to introduce you to John Hallett and Jenny Jaeger.

John and Jenny, let’s start with your story. We’d love to hear how you got started and how the journey has been so far.
We started out as a Krav Maga gym in 2006 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.

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 offering Crossfit. 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 is not what we are about.

Overall, has it been relatively smooth? If not, what were some of the struggles along the way?
The two hardest things in a small business are finding an affordable lease. The cost of all real estate in Colorado has risen substantially, pricing for gym memberships has not. The second challenge would be marketing. It was a lot easier 15 years ago. There are so many social and media platforms now that it makes it hard to reach new costumers.

Rocky Mountain Self Defense & Fitness – what should we know? What do you guys do best? What sets you apart from the competition?
We offer Krav Maga, Fitness Classes & Crossfit classes for kids & adults.

What makes us most proud at RMSDF is hearing from our members how their confidence has increased. Whether it’s from our self-defense side with Krav maga or from our fitness members. We love empowering people!

We are a family style gym with a small home town feel. Where in a world taken over by big chains and bigger is better. We keep the small welcoming feeling, where we know all our members and their goals.

What is “success” or “successful” for you?
We want our members to achieve their goals and feel welcome coming to RMSDF. When we hear from members in person or when they leave a review on google of how much they love coming to us, it makes all the hard admin work of running a gym all worth it. It is truly why we do it. We love building people up. Life is hard, we are here to help everyone “build a strong mind and a strong body” to be better at life.
