The majority of kicks so far I have found get more "rolling hip action" if you pick up the knee sharply first. begin with knee pointing upwardish(depending on the particular kick) and finish with the knee horizontalish(depending). example would be the side turning kick...knee up, leg chambered, swing upper leg which swings the rest, and as you kick the leg twists from the hip so the knee which was once almost vertical is now horizontal at the moment of impact. Almost impossible to explain typing, your pants snap though. lol. Twist like fist.
Kicks aside, what about the patterns? truthfully the original question was meant more for hand techniques, but it is good to talk about kicks too, they are equally important. Like I can get guys to use hips when doing forearm or knifehand blocks, if there is a reaction hand they seem to be ok. But other blocks (which to me are exactly the same thing in terms of hips) they dont use their hips at all. Like the twin forearm blocks, anything spinning aswell, like Dan-Gun and Do-San the knifehand stikes. I keep telling them "its spinning, there should be crazy power in those", but they turn, face, and THEN strike. ARRRRGHHH!!! LOL!
