By the way, I thought Chinese styles called these whirlwind kicks?
[/QUOTE]
The whirlwind kick/tornado kick is a type of crescent kick, just with more complex footwork. (You also have this in TKD.)
Crescent kicks are definitely in traditional Chinese forms, but the Kung Fu forms do strange things sometimes. For instance in northern forms, they do a front straight leg swing, (like a cheerleaders kick,) which would be very impractical in fighting. I have seen people interpret this as a type of sweep, a knee strike or a heel push kick. All of that seems absurd, since all those techniques are already represented, more realistically in the forms. I think it just is what it looks like. A leg stretch. Stretch kicks are important to northern systems so it’s not really surprising they would put the exercise in a form.
I agree with Bawang that outside and inside crescents in the forms are meant to be stretches. I think people may have later learned to make them work in sparring. I’m not so sure of his statement about the tornado kick being a roundhouse. He probably read something somewhere that made him arrive at that conclusion, if he did, I wish he would share…
