Turning your back doing a technique

[Kensai]

I think that kicks in general are hard to apply in real life, however it is even worse in the case of spinning kicks that both feet are off the ground. As a general rule, kicks should stay below the waist.

I never thought about it really. But if I think about it, I don't even turn my back in sparring. For throws (Judo) yes, but not sparring (TKD).

When I see my opponent start his turning back kick I start my own front push kick to nudge him/her off balance thereby nullifying the accuracy and power of the kick. I use the bottom of the foot and just a slight push usually on the tush. I've never gotten a warning because when I initiate the attack the opponent has not yet exposed their back and it's not designed to score a point or hurt them. My instructor says it's a-ok so I use it when I am too close to avoid the kick.

 

A back kick has to be lightning fast to be used offensively.

 

The safest way is to use it to counter an opponent that has committed to a technique (such as a round kick) Another favorite use is when an opponent has side stepped to avoid a roundhouse and you quickly reverse directons to catch him from the other side.

 

I wouldn't reccommend any fancy spinning moves in a real fight because like someone said having one's back to an opponent of an unknown style could get you tackled/choked out or leg trapped and your pretty face dragged across the road...Ouch!
