the strange thing is that (i feel) most of the martial arts all come down to the same thing in the end: beating the other person/s in a fight situation or confrontation, even using psychological methods to avoid a fight at all.
along with the health benefits and enlightenment and sometimes just plain enjoyment that
karate, kung fu, and korean arts can bring.
but people are endlessly bitching and arguing about which style is better,
yet i have endlessly seen similarities between japanese and chinese styles, as if they are sort of entwined and cross over in various places along the respective journeys, sometimes even the EXACT same techniques, but people are always putting other arts down.
it has been said that
karate(japanese) starts off "hard" and softens and flows as one progresses on their journey (this i can testify to)
and uses a more common power with technique.
there tends to be lots of big warm-ups and stuff like that, but ironically features lots of chinese styles.
whereas wing chun kung fu, for example (chinese) begins using almost complete relaxation, and soft training (which is really hard to get used to when you are used to training in other styles that use "hard" power) and relies on there being no wasted effort, very close range with small movements, and machine gun type speed attacks.
creating muscle mass is considered bad as it will slow you down.
i don't know much about korean arts.
either way, it's up to the individual martial artist to properly apply their art and make sure it's doing what it should, sometimes there are perfectly good clubs but maybe a student just has'nt applied themself or has'nt bothered to squeeze the best out of their resources and not down to
karate, kung fu, or anything else being rubbish as such.
