I've got a BB in Taekwondo. Many might think its a useless art with BJJ and MMA coming up.
But nothing beats getting into a street fight with some smart ass who wants to show his friends how tough he is then proceeding to round house him in the jaw, knocking him flat on his back.
I haven't been in it for about 3 years now but its something you don't forget.
I'm starting BJJ soon.
