Every fight begins on your feet and ends up on the ground. Because of this, we believe you should train that way in order to be prepared, whether it's on the street or in competition. Our system at The Sanctuary Brazilian Jiu-Jitsu and Judo allows you to develop your game on your feet and on the ground.
Brazilian Jiu-Jitsu and Judo are the best martial arts for self defense.

Build Strength and Confidence with Fitness Classes, CrossFit, and Personal Training in Littleton, CO
When you step onto the mats or into our training space, you’ll feel the difference immediately. At The Sanctuary, our fitness classes, CrossFit sessions, and personal training programs are shaped by the same values that guide our jiujitsu classes—community, respect, and progress. We’re not just here to count reps or demonstrate exercises. We’re here to help you grow physically and mentally. Our approach blends functional conditioning with the discipline found in Brazilian jiujitsu classes, meaning you’ll train with intention and purpose. Whether you’re exploring jiujitsu and fitness for the first time or expanding your athletic journey, our coaches make sure you always feel supported.
Our background in MMA and mixed martial arts classes gives us a unique perspective on fitness. We integrate functional strength, mobility, and conditioning principles inspired by martial arts training into every program, creating well-rounded athletes—not just gym-goers. You don’t need to be interested in fighting to benefit from this structure. The concepts used in judo, judo classes, and self-defence classes all contribute to helping you move better, react faster, and build real-world physical capability. When you train with us, you’re not just checking off another workout. You’re building life skills that improve your everyday confidence, resilience, and physical awareness.
Our training methods are built on practicality. That’s why self-defence principles are naturally woven into much of what we teach. Whether you’re working with a personal trainer, joining fitness classes, or exploring CrossFit-style workouts, you’ll develop strength that translates into real-world capability. Many of our students begin with jiujitsu or self-defence classes and quickly discover how fitness and technical training complement one another. The more conditioned you become, the more empowered you feel in all aspects of your life. Our Littleton community includes parents, athletes, professionals, teens, and everyday people who simply want to feel stronger, safer, and more capable.
