OUR HEAD INSTRUCTOR
Experienced coaching from your first session.
Ben Babbington
Founder / Head Instructor · Havoc Grappling
Ben founded ZKS Martial Arts in 1999 and has nearly 30 years of experience working with children, teenagers and adults. He is a 1st Degree Brazilian Jiu-Jitsu Black Belt.
For a new member, that experience means clear explanations, help with unfamiliar movements and an appropriate pace from the first session.
Ben continues to train and compete himself. He won two silver medals at the National Masters BJJ Championships in September 2026. That experience informs his coaching; it does not make competition a requirement for members.
Competition is available if it interests you. Training for enjoyment, technique and fitness is equally welcome.

YOUR PROGRESS
BJJ belts: a journey built on practice.
You start at white belt. The main adult BJJ belt sequence is white, blue, purple, brown and black. Each stage represents continued learning and experience on the mats.
- WhiteStart here
- Blue
- Purple
- Brown
- Black
What do the stripes mean?
White, blue, purple and brown belts can each have up to four stripes, marking progress within a belt. Black belts have a separate degree system; the journey continues after black belt.
Progress at your own pace
Promotions recognise your development. Your instructor decides when you’re ready, so there is no promised date for your next belt. Focus on learning, regular practice and being a responsible training partner. You do not need to compete to train and progress at Havoc.
The wider BJJ grading structure also includes senior red-and-black, red-and-white and red belts. See the IBJJF graduation guide (opens in a new tab) for the full structure and age requirements. BJJ grades are separate from the ZKS Taijutsu grading system.
