Course description

Learn The Complete 4D system 


As you may know 4D is an evolution from JKD and Kali. All things have to evolve. 

We’ve done that concentrating on Stand up combat. Where all fight start and most end. 

The name 4D comes from the four elements inherent in stand up combat. 




Weapons: Stick and knife 

Group attack

To get great at all of this would take many lifetimes. We do it by keeping it simple and instinctive.

Come and join us as we take you from deep fundamentals to the most advanced martial art concepts and techniques and give you ownership and amazing skills you can trust

What will you get as a member of the 4D Online community? 

We’ll send you about four videos’ a month plus bonus footage. These videos will walk you through key concepts or techniques from the 4D system. I will show you the why and how of each of the techniques, plus what it looks like in a live situation. 

Our goal is to give you ownership of the system and root it in your bones and we are dedicated to doing what is needed to get you there.

It's like having me as your personal coach. 

On top of the regular instructional videos, you’ll receive a PDF explanation and checklist for each technique. 

These checklists are revolutionary in the martial arts world and will be like having me standing near you, guiding you through the techniques. 

Access To Exclusive Seminars and Workshops. 

You’ll also get regular bonus footage from my seminars, workshops, and classes which will reinforce the subjects you're learning in the main videos.  

These videos alone are worth the value of becoming a member. 

50 Years In The Making.

Until now, the only way you’ve been able to master the 4D system is by training privately with me. If you wanted to do that, I typically charge around £200+ per hour. 

However, you won’t need to pay anywhere near that much to join 4D Online. You see, I want as many people as possible to benefit from the system, so we are doing a special offer of only   £12.99 per month.
