Zen Do Kai is a style of matrial arts...like karate, only better. It's a mix of everything, Muay Thai, Boxing, Winchung, Judo, Wrestling...little bits and peices of everything. It's Japanise. Works on a belt system (white, yellow, orange, blue, green, brown, black - then the ten degrees). I'm currently a blue belt and my boyfriend is a first degree black...so I have my very own instructor. His dad is a probationary second dregree and his younger sister got her brown belt the same day i got my blue.
It's great for self defence and confidence. Fitness and (owing to the push ups and sit ups, among other things) a little toning as well. It's not difficult to pick up either.
Depending on where abouts you are in Adelaide would depend on what dojo (training place) you'd go to. I know of one in Golden Grove, cause a few of the guys that used to train in Pirie train there. If you're interested, I can have a look for you, or you could have a look at the website (http://www.bobjonesmartialarts.com.au
) it's got a heap of information on there about the style and stuff.
Good luck with everything!
