Over the past 20+ years of training and teaching martial arts, one of the things I’ve always loved most is watching people grow through the martial arts journey. Seeing new members start out, keep showing up, putting in the work, and eventually begin to make their mark in competition is one of the most rewarding parts of being part of this community.

Through THEØRY and events like the THEØRY Grappling Invitational, I’ve had the chance to see a lot of those moments up close and help spotlight some really talented rising athletes as they step onto the competition stage.

These experiences made me realize how many people in this sport are grinding every day and building something special long before anyone outside their gym really notices, along with the challenges of being seen and noticed for grappling opportunities.

Because of that, I started a new project called "The Center Mat". The goal is to create a place that highlights and showcases rising grappling athletes as they continue to grow in the sport, and provide opportunities for them to be seen and recognized.

If you enjoy following the next generation of grapplers, or if you’re an athlete (or know an athlete) building your way up through the competition scene and want to be spotlighted, I’d love for you to check it out and follow .

Huge congratulations to Erick Acosta on achieving his 3-Stripe White Belt with a lot of dedicated focus and training with a sick D'arce as well), along with Eileen Spence who achieved the Purple Belt rank this weekend! Purple is very much considered the "Baby Black Belt" and a rare achievement, with many knowing the path from Blue to Purple is filled with lots of difficulty and challenges. Once again, congrats to both!!!

DAY ONE: Foundations Workshop
📅 January 3
⏰ 9:00–10:00 AM
📍 THEØRY Jiu-Jitsu Studio

A lot of people start the new year looking for something new. Not just another routine, but something they can actually stick with. Something engaging, challenging, and worth showing up for.

Jiu-Jitsu offers that. You’re learning a real skill, not just going through motions. You train your body and your mind while being part of a supportive community focused on learning, safety, and improvement.

DAY ONE is our formal beginner introduction to the world of grappling and how it works.

This workshop covers the core foundations of Jiu-Jitsu and what matters most early on. At THEØRY, our curriculum is structured so you never feel lost or overwhelmed at any point of the journey. While this same onboarding approach is present in every class, DAY ONE gives you a clear, intentional starting point.

If you’re curious about trying something new this year and want a simple, welcoming way to start, this is it.

January 3 • 9–10 AM • NO EXPERIENCE NECESSARY

Every leg lock begins long before the submission clamps down. It begins with connection. If your opponent can anchor to you, they can start building the structure that leads to entanglement.

Your first job is to deny those connections. Not with panic. With clarity.

Breaking ankle grips removes the steering wheel of their guard. Clearing hip grips removes the frame that slows your retreat. Once these early connections disappear, the path into leg entanglements becomes harder for them and far more predictable for you.

Escaping is not only about the moment you are caught. It is about the seconds before that moment, where a small denial prevents a large problem.

When you learn to control your opponent’s ankles as they you enter, you reclaim initiative. You decide the direction. You set the pace. Instead of reacting to their entanglement, you make them react to your posture and movement.

CONTROL BEGINS WITH WHAT YOU REFUSE TO GIVE.

Join us this Saturday at 10am at THEØRY for our Leg Lock Escape Seminar. Learn to stay safe, stay calm, and stay one step ahead. Reserve at THEORYJIUJITSU.COM
