Target the knee

99% of people would miss the knee leaving yourself open to being stabbed. On top of the fact not many people run at you with a fully extended knee. This is just bad advice all around.

The effect depicted in this video only works if the knee is already at full extension. A leading knee by definition is never extended. Only the lagging knee is fully extended. However, when weight is balanced forward, a front push kick to the lagging knee will only send the entire leg backwards. To actually be in a position to “break” the knee joint as depicted, the victim would have to be moving backwards—for instance trying to maintain footing if pushed/tipped/slipped/struck backwards.

間接蹴りって危ないから、空手でも禁止されてましたよね。

Theoretically, this could work, but the timing would have to be impeccable. No room for errors or mistakes.

I did that once to a six foot five charging inmate and he went down like a ton of bricks 🧱 👀

Try this?

It's too easy to miss

I would watch the knife at all times. You can kick the knee without having to take your eyes off the knife.

Nice move! From the side, it’s also very effective and unexpected!

I like

most people would miss so front kick the belly and run while watching your back

@grok is this good self defense skill?

Not an easy task. It will not workon a bended leg. It´s not easy to synchronize a straight leg with your optimal distance for the kick.
