What is "Karate-do" and "Kime?"
Karate-do is physical exercise leading to mastery of all body movements. Techniques are precisely controlled according to the karate-ka’s ill power and are directed at the target accurately and spontaneously.
The essence of karate techniques is “kime.” “Kime” means and explosive attack to the target, combining the right technique and maximum power in the shortest possible time – “focus impact.” “Kime” may result from striking, punching or kicking, but also from blocking. A technique lacking “kime” is never true karate.
Through training, parts of the body become weapons to be used freely and effectively. The most essential factor is self-control. To become a victor, one must first overcome his own self.
