Martial Arts for Everyone

SDSMA COVID-19 Response

As with all but the most essential business and service suppliers, SDSMA have had to close its doors until such time the Covid-19 pandemic has been banished from all our lives.  SDSMA are however working to keep our classes available by using the power of the internet.

We are posting daily Live Facebook videos of Karate, Kick Boxing, Boxing and Muay Thai for you to join along to. Our instructors are also using Facebook Facetime or Zoom video conferencing for a more interactive experience for smaller classes of students.  Details of these are being posted daily to both Facebook, Twitter and Instagram.

All of these sessions are being run for free, and for those who have left their contracts in place we are extremely grateful.  But we appreciate many of you are finding this uncertain period very difficult and we do understand if you have to cease your existing contract.

We have now created a fund raising page should you wish to make a donation towards SDSMA’s future.

Please Stay safe, stay at home, help and support our NHS

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.
