What sets The Sanctuary apart is our foundation in martial arts and functional movement. Our fitness programs complement our jiujitsu classes and Brazilian jiujitsu classes, giving you a well-rounded path to strength and conditioning. You’ll train in an environment where technique matters, where coaches pay attention to detail, and where every movement is chosen to help you develop balance, stability, and power. Whether you’re exploring MMA, mixed martial arts classes, or just want to improve your overall fitness, our training methods support better body awareness and long-term progression.
Our crossfit-inspired training blends athletic conditioning with explosive functional exercises that support judo, judo classes, and other grappling-focused martial arts. Even if you’re not here to compete, you’ll still benefit from training that improves speed, coordination, strength, and mobility. Every class is guided by experienced coaches who help you move safely, push confidently, and avoid injury. We build workouts that feel challenging but achievable, allowing members of all ages and fitness backgrounds to progress at their own pace while still experiencing a full-body transformation.
Personal training at The Sanctuary gives you the opportunity to strengthen your body for both daily life and self-defence classes. Many of our members use personal coaching to enhance their jiujitsu and fitness goals at the same time. Whether you want to improve endurance for rolling, gain strength for takedowns, increase flexibility, or learn better movement patterns, we create a strategic plan that fits your martial arts journey. Our coaches offer consistent feedback, motivation, and support, making sure you stay focused and confident through every step. The result is a stronger, more capable version of yourself - on and off the mats.
