Any martial art requires long long long hours of practive and forceful opposition training (read near full contact sparring - like they
used to do in karate in the US). Without that, no martial art is useful. You can say "i'm going for the groin and eyes!" but your just thinking about a fight instead of fighting it. You simply take whatever target is available without trying to force a shot at a specific body part. You can win a fight with a finger hold.
The most dangerous thing a martial art sudent can do is
think they know how to fight. If/When a student receives a blackbelt, it merely means "your not a complete fucking idiot in this style anymore."
maniacs "a-ha" moment came about due to repetition and body memory. He acted without thought because by then he instictively understood how to move himself for best defense, because wrestling practice actually requries using the moves daily. He had day in and day out performed in near full force against other wrestlers, therefore thought was no longer necessary about how to perform the correct movement. Practice like this is the only way to truly learn. It is learned through long hours of practice and experience. The problem with most martial arts (at least where I live) is that very few of them actually allow application of the art (fucking liability lawyers!!!!!!!!!) in practice. This makes it useless. You can have the prettiest back spin kick in history. If you havent tried in a real world application, its useless.
Krav Maga does rule.
Jeet Kun Do does also, since it applies the idea of no forms, simply reacting to the situation.
Also, never never never discount a boxer. He/She has spent 1000's of hours in a ring, perfecting their ability to repeatedly hit you in the face, against opponents attemting to do the same thing. The moment when you think "i will go for his groin" is the moment before you "come to" from a ko, or worse.
"Krav Maga trains combatants for situations where losing would be potentially fatal.
Any martial art that doesnt teach this is a waste of time. Every fight should be considered life and death. The reasoning of your opponent is unknowable. You simply
must remove from them the ability to cause you harm. To do anyting less is ridiculous. OTOH, you do have a moral obligation to avoid causing undue harm to others. If you can end a fight without severely injuring your opponent (or worse), then you should do so as long as you believe the opponent will not continue to be a threat in the future.
Avoiding the fight in the first place is still the best option, if available.
oh, BTW, just for grins, I have received training in:
Karate, TKD, Shaolin Kung Fu, Chung Moo Do ( a collection of 8 other arts, but not really that good), junior high and highschool wrestling, US Army self defense. I tried boxing but only got hit alot. My handspeed isnt exceptional, sadly.
@hawkfrost - I hope I am wrong, but I perceive a bad day in your future.
