I would like to ask: is there any free martial art classes available in KL/Selangor?

I am not trying to be funny, or trying to compare between locations, its just that, here in Tokyo, there are several MA classes that are offered for free to anyone, most of the time done as volunteer groups (no hidden agendas or anything like that), and I've joined a couple of them.

Hopefully no one will misunderstood my question, thank you.
