hi june, this is a very good self defense. you might wanna check it out at gymnasium yang tak brape bercawangan sana sini, those pop gyms selalu takde. i do not know any for now but i have seen a lot of flyers and posters around my office at sri hartamas, gym2 ni yang kat atas shop lots normally have lessons/classes for martial art yang memang tulen.
good luck.
