I was told nunchaku are ninja weapons because I saw them in Teenage Mutant Ninja Turtles cartoons and comic books and movies. But Bruce Lee uses nunchaku in his movies. And he was neither Japanese nor a Ninja. According to some websites, nunchakus originated from Okinawa where they were introduced by the Chinese. But I'm not sure these sources on internet are accurate. I don't know whether they have disclaimers or not.
I have studied Arnis for one semester and I've forgotten most of the moves including grappling ones. I remember only the basics of Arnis. What martial arts should I take and please give me your reasons why I should study your recommended martial arts?
