Real Martial Arts for Good People • Valencia
Welcome, I'm coach Justin and this is Good Fight.
This is modern martial arts in Valencia shaped by two major influences: my traditional training with Sensei Rick Hotton, where I learned to go deeper into the mechanics, relaxation, and movement of Shotokan karate, and my modern training through Machida Karate, where karate comes alive through timing, distance, pressure, takedowns, and real application.
This is not karate where you stand in lines, punch the air, and pretend to be serious for an hour. You’ll move with purpose, learn to breathe under pressure, and stay steadier when things get uncomfortable.
Karate is the foundation, but Good Fight is not limited by style labels. We also draw from Brazilian Jiu-Jitsu, Judo, and functional Aikido principles.
You’ll be challenged, but not judged. Coached, not barked at. Pushed to improve without being made to feel small.
Good Fight is for adults, teens, and kids who want real training without the stiff dojo energy. We take the training seriously. We don’t take ourselves seriously.

Please Don’t Call Me sensei
I prefer Coach Justin. I’m not interested in titles, hierarchy, or putting distance between teacher and student. What matters here is clarity, competence, and care — showing up prepared and helping people improve.
My background is in modern Shotokan karate, where I spent years studying the mechanics of movement and application under Sensei Rick Hotton. Over time that training expanded through Machida Karate and ongoing practice in Brazilian Jiu-Jitsu, along with periods of study in Judo and Aikido. Through all of that, my focus gradually shifted toward what actually holds up under pressure — timing, structure, balance, and practical movement with partners. That’s the experience Good Fight grew from.
I don’t teach the way. I teach a way — one that gives you tools, principles, and structure so you can build a practice that fits your body, your temperament, and your life. My job is to meet you where you are, keep you safe, and help you move forward with confidence.
If you’re willing to train with intention, ask questions, and take responsibility for your progress, you’re in the right place.
