In a real altercation, I would say I agree, the head is not something I would probably ever consider (never say never IMO) but I am with you there. Body though, I probably would be a little more open, a good front thrust kick or front leg side kick is not something people know how to deal with very well and could, in certain circumstances be very useful. Agree on keeping the kicks low, if you use them at all.

As for head kicks, if like most of us the only fighting we will hopefully every do is in a sporting environment, then they are great weapon to have. If you use them sparingly, they can become a much higher percentage strike. Especially if you set them up correctly. Of course if take downs are an option you need to be that much more careful.

Not disagreeing with you, head kicks are for sport only.

Allright, no machines, got it . I read (and heard) another way of eventually getting flexibility is to stand close to a chair/object and do roundhouse kicks above it, and eventually get closer and closer to the target, forcing you to kick higher :D, so ill do that instead ^^

A head kick is exciting to see in MMA fights or a demo but it is not advisable in a real fight/street fight. Your opponent is more likely to catch your leg and take you down if you do head kicks.
