Why Brazilian Jiu-Jitsu?
The Art of Leverage and Technique.
Brazilian Jiu-Jitsu is a highly effective martial art and self-defense system that relies on principles of leverage, momentum, and body positioning rather than sheer strength. This makes it a unique and accessible practice for anyone, regardless of size or athletic ability. While the techniques may seem complex at first, they are designed to be learned and applied with consistent practice. Your commitment to showing up and learning is the most important factor in your progress.

“We absolutely love Knots! Coach Cassio is incredibly knowledgeable, professional, and friendly. He creates such a positive learning environment for the kids, and you can tell he truly cares about their progress and confidence. His wife Natasha is always there to welcome everyone with a smile and offer help, which makes the whole place feel so warm and inviting.

“As a beginner in Brazilian Jiu Jitsu (BJJ), I couldn’t have asked for a better gym. The instructors here make learning self-defense and martial arts both fun and approachable, even if you’ve never trained before.
The BJJ classes are structured so you build skill quickly — from takedowns to submissions — and you always roll with partners who help you improve. The atmosphere is welcoming, supportive, and filled with people who are passionate about training.
Whether you’re looking to get in shape, compete in jiu jitsu tournaments, or just learn real self-defense skills, this gym is the place to be. I highly recommend it to anyone searching for the best Brazilian Jiu Jitsu training in Moncton.”
