Fitness, Fighting, & Self-Defense

These are our three primary areas of expertise, and the top reasons our members train with us.

Whether you want to build new habits, shake up your exercise routine, or advance your martial arts skills, KruFit can help you reach your goals.

Martial Arts for All

Kickstarting healthy new habits is tough – we get it! Maintaining those habits can sometimes be more difficult. Our coaches offer up new curriculum every week so your workout is never monotonous or dull.

Our members span a wide range of fitness and skill levels. All that matters here is showing up, being a good teammate, and doing your best!

What Makes KruFit Different?

Short answer: our community. While our workouts are intense, our people aren’t (at least not in the “gym bro-ey” sense). Yes, we’ll push you to meet your goals, but we celebrate personal growth and grit without the trash talk and egos.

Every KruFit member is on their own personal journey. Our community values each journey equally and we all contribute to each others’ success. Come try a class and see for yourself.

“We had a great experience with Kru-Fit and the self-defense class. Coach Jamie was wonderful with my kids and they took a lot away from their session. We will definitely be back.”

About KruFit

I began training Muay Thai with the goal to lose weight while learning some practical self-defense skills. What I found was an art form that not only transformed my body, but also my mind and my life. Since then my passion has only grown and taken me around the world to learn from some of the world’s top Muay Thai fighters, coaches, and organizations.

In addition to Muay Thai, KruFit has recently expanded to offer two other programs: Academic Grappling Brazilian Jiu Jitsu, led by Coach Jared Loper, and Colin’s Boxing Club, let by Coach Colin Herschel. No matter which program(s) you’re interested in, you’ll get attentive and supportive coaching.

I love the gym community we’ve built here. There’s always something exciting happening at KruFit. I can’t wait for you to visit us and try a class for yourself!
