Kid’s Classes – Why the Honey Badgers?

Honey badgers like honey and look cute. However, they are also in the Guinness Book of Records as the world’s most fearless animal. They are intrepid, ferocious, and smart, and these are the qualities that we want to instil in all our junior members. OTT is committed to teaching all our members, but especially our junior members, ways to avoid conflict, and how to defend themselves when they face verbal or physical threats. At OTT, we also understand the importance of ensuring our members appreciate that the skills we teach them are only to be employed if they are at real physical risk, and that the force used needs to be reasonable.

Tackling Bullying Head-on

OTT is committed to stamping out bullying in all its forms, and this is why we are proud to be associated with BulliesOut, a national charity dedicated to tackling bullying.

Our Instructors

Our Head Instructor is a former police officer with an enhanced DBS certification, and for our junior classes, he has the assistance of Maisy and Lily, who have previously assisted as junior instructors at a local Krav Maga club. As well as having been Krav Maga junior instructors, both Maisy and Lily have extensive martial arts experience, and will act as great role models for the Honey Badgers.
