Combined Jiu Jitsu Course Introduction

Taking the best of many styles and combining them, Grandmaster Kranstz formed the style of Jiu-Jitsu called Combined Jiu-Jitsu Arts or CJA.

Grandmaster Robert Kranstz has had a distinguished martial arts career for more than 45 years. During that time, he has acquired many titles and awards and holds an 8th Dan with a Kyoshi title. He was one of the original pioneers of sport Jiu-Jitsu. He opened a school in 1974, which is still successful today. As the World Kobudo Federation representative for Canada and other countries, he works to build and better the organization.

Grandmaster Kranstz attributes his success to the people he trained and studied with over his martial art career like Bill Wallace, Joe Lewis, Renzo Gracie, Jean Yves Theriault, and Dan Severn only to name a few.

CJA specializes in Jiu_jitsu as a sport and as a self-defense program.

How do the IDMA courses work?

The IDMA courses are made up of multiple levels (similar to belt levels) that are arranged in order of difficulty and skill level.
Courses start with the basics and gradually move to more advanced concepts and techniques. Each level is broken down into numerous individual videos, consisting of techniques, concepts, and forms. The breaking down of each level with many short length videos maximizes learning potential.

What do I get if I buy a level?

Each level (belt level) is purchased individually. You receive unlimited access to the content of the level purchased for a period of one month, for only $9.99 USD. Levels are approx 45 minutes in length.

How do I Sign up?

Signing up is easy, and if you encounter any problems, follow our 'How to Register for a Course', which takes you through the registration process one step at a time. Should you encounter any difficulties contact us.
