About Function Jiu Jitsu (Impact JJ)

At Function Jiu Jitsu in Billings, Montana, we offer a diverse range of martial arts and fitness programs designed to serve students of all backgrounds and goals. Our curriculum includes gi Jiu-Jitsu, submission grappling (no-gi), Kickboxing, Yoga, Restoration, Women's-Only classes, and Kids Jiu-Jitsu.

Our gi classes focus on the advantages of the traditional uniform in controlling and submitting opponents. Our no-gi submission grappling is dynamic and fast-paced, designed to build fluid, adaptable movement. Kickboxing develops stand-up striking fundamentals. And our Yoga and Restoration classes help practitioners recover, improve flexibility, and sustain a long martial arts journey.

Function Jiu Jitsu operates a dedicated Women's-Only program for students 14 and up in a welcoming, supportive environment. Kids classes offer structured BJJ and grappling training in a safe, positive space. Reach us at 406-272-6377 or functionjiujitsu@gmail.com.

I love training at Function Jiu Jitsu. As a beginner I love being able to follow along and be immediately included in whatever drill is being done and learning as the experiences happen. Great bunch of people. I would certainly recommend as a gym to get started or as one to grow your skills.

I dropped in for the evening gi classes. Chris was welcoming and the crew I got to train with were great training partners. I’ve tried other BJJ gyms in the Billings area and this is easily the best one I’ve been to. Thanks to you all and I will definitely be back! 🤙

Function Jiu Jitsu is amazing! The coaches and kids made us feel welcome and supported starting on day one. They are knowledgeable, patient, and truly care about every child’s progress—both on and off the mat. The kids treat each other like family, celebrate each other’s success and push each other to grow. Learning Ju Jitsu in such a positive environment teaches discipline, respect, perseverance and self-worth. The facility is always clean, the pricing is very reasonable, and the class times are perfect for working parents. We’re so grateful to have found Function Jiu Jitsu and can’t recommend it highly enough!

I was traveling for work and had the opportunity to drop in and train at FxJJ. The focus of class was back escapes and back retention. The instruction was excellent, the positional rolls provided reinforcement, and the training partners were awesome. I am greatful to find such exceptional training while traveling.
