Memento_mori: I was once taken to class on one kind of Eastern combat. Worked for a while. She pressed, stood on her fists, stretched - tired, in general. Once I was placed there in a sparring: my 50 kg weight and 164 cm of height against a man 190 cm of height and 100+ kg of weight... This is all you need to know about the benefits of Eastern combat for self-defense. But the Kadochnikov system works in such cases unsuccessfully :-)
