Welcome to Warrior Dojo
Train Power from the Inside Out.
At The Warrior Dojo, I believe every martial artist carries the potential for mastery — not just in combat, but in life.
Here, you’ll find a complete library of courses dedicated to the art and science of solo training — the same timeless methods once used by samurai, monks, and modern warriors to forge strength, structure, and spirit.
Whether you practice Karate, Wing Chun, BJJ, Tai Chi, or MMA… the principles are universal.
From internal power and breathwork to isometric strength, mobility, and combat conditioning, each course is designed to help you move with grace, strike with power, and train with purpose — anytime, anywhere.
Explore lessons that blend ancient internal methods like Zhan Zhuang, Reverse Breathing, and Aiki with modern strength systems like kettlebells, bodyweight mastery, and resilience training.
Each course is built by lifelong martial artist and strength coach Jon Haas, combining decades of cross-disciplinary experience into clear, actionable systems that deliver results you can feel from the very first session.
This is more than fitness.
This is more than technique.
This is your path to becoming a complete warrior — strong, fluid, grounded, and unbreakable from the inside out.

I have spent over 30 years - a lifetime - training, studying and working with the best in the areas of martial arts, internal power development, and strength and conditioning to figure out how to reverse engineer the ultimate in human performance for martial art, combat sport, and living a powerful, healthy warrior lifestyle.
