Guys,
the exercises I think he is talking about are the aiki-taiso warmups. What is hidden in them is the entire technique of aikido, and I taught a class at the Okinawan Karate Union seminar one year on that very subject. Your poster is correct that they are a series of dynamic stretches and breathing exercises, but they are also much more. They teach the correct movement for blending into almost every technique and if the taisos have the full knowledge, they also teach the movements that are necessary for correct footwork.
I can't tell you how many times I've asked a student how we did one of the movements in the warmups, and then asked them why they didn't do the same thing when we were doing a technique. If there's a secret in the martial arts, it's found in the aiki-taiso exercises used for warming up almost every aikido class in the world.
