I have been attending some Wado Ki Kai workouts at CoM Kentfield over the last few weeks. It is an interesting style, and different than what I can recall from attending Ito's, which was like Koshu Ryu Kenpo.
In the summer & the overwhelming heat though, you sweat like mad doing the Wado Ki Kai excercises -- even the stretching. Earlier today, I was checking out wadokikai.com. I noticed they have some QuickTime videos of each Kata (movement excercises, varying by belt ranking) which might be of some interest to view.
