Little Ninjas Prep

Ages 2-4

Little Ninjas Prep is a martial arts themed exercise programme where parents and children enjoy classes together.

We work on the 6 Cs: confidence, coordination, concentration, control, courtesy and cooperation.


once weekly

Little Ninjas

Ages 3-6

Our Little Ninjas programme fuses gymnastics, games and martial arts to build solid foundations for the Junior programme. In addition to working on physical fitness and coordination, children learn about safety and keeping healthy, and develop their social skills.



Ages 6+

Children move through different coloured belts or 'kyu' learning the fundamentals of traditional karate, and working on developing cardio fitness, coordination, power and control. At later grades kickboxing is also introduced into the examination material.


Adult Martial Arts

Ages 14+

Our adult classes are open to all levels of experience and fitness. In a typical class students might undertake strength and cardio training, traditional Japanese karate, raw street self defence, Brazilian Jiu-Jitsu, or Filipino weaponry (all in a safe and friendly environment of course).

Why does my child have to train twice a week?

Twice a week training is a firm policy of OSMA. Some parents ask if they can pay the usual membership rate and bring their children only once a week. This is a definite no! Twice weekly training is about motivation, quality, relationships and effective educational experience. A child training once a week is not only progressing painfully slowly and is likely to be demoralised by other students promoting sooner – they also hold up the group requiring extra explanation and attention. 100% twice weekly class attendance is required. Classes missed for the unforeseen should be accounted for with booster sessions (no extra charge).

If my child does miss a session in the week what can I do?

As a member of OSMA you are entitled to attend any of the classes for your particular age and ability. Please note though, that all classes run on an A and B cycle during the week, in 2 progressive sessions. This mean one must choose a ‘base pair’ of classes and then can add others. Please email for further explanation.

Do parents stay?

We ask parents to stay and watch the first two introductory classes. After this, our safeguarding policy requires no spectators. Parents must arrive promptly at the end of the lesson when there is a debrief to explain the home practice. Examination sessions are open for parents to watch.

The Foundation Student Creed

I promise to be a good student (hold right hand up)

To feed my mind
(point to head)

To strengthen my body (make a muscle)

To have truth in my heart (put hand over heart)

And to make great friends (shake the hand of the people next to them).

The cadet Student Creed

I promise to develop myself in a positive manner and will do my very best to ensure my mental growth and physical health.

I will develop self discipline in order to bring out the best in myself and in others.

I will use common sense before self defence and will never be offensive or abusive.

We are a black belt school, we are motivated, we are dedicated and we are on a quest to be our best!
