TKD: Proper Front-kick/Snap-kick question
Something has been bothering me about the new school I've just recently joined, and it has to do with their variation on the front-kick, something I'm used to calling a snap-kick.
Their front-kick is a pushing motion, similar to a side-kick, but with more emphasis on pushing with the ball of you foot (no heel at all). There is no snapping motion (which I believe is bad for you knee anyway, isn't it?) with the leg, but an extending push. Almost not even a strike.
Another strange practice (as far as I am concerned) is that their grounded foot is supposed to pivot outwards 90 degrees. If you're not supposed to have your knee perpendicular for a side-kick push, why the hell would you for a front-kick push?
Does the rotation of the hips provide that much more power to this relatively weak kick, or does is this just a stylistic thing that the teacher has been taught?
I know proper hip rotation can provide the majority of your power with many kicks, but is this the case with a front-kick/snap-kick?
