We are now based in a leisure facility in Colchester, with a large purpose built dojo, Energyze Gym and Fitness centreUltimate Ninja UKEnergyze Beauty and Wellness Clinic (including Energyze Tanning), Energyze Kitchen.

We have built our reputation on professionalism, achievements and quality of student service.

Our classes will help you achieve lifetime self-defence skills, build confidence, get into shape and relieve stress.

From our Colchester base, we attract members from across north Essex who are keen to learn a range of disciplines including karate, boxing, kickboxing and Krav Maga.

We offer dedicated classes for toddlers and young children, Little Dragons, which are designed to be fun whilst building core skills which will benefit them in the years ahead.
