I want to learn self-defense which really works and where you do not find out after years of practice
that what you learned does not work in a real fight.
I watched a few videos on y-tube by someone called "martialartsteacher". I don't know if he's legit.
I think he does MMA and also does real fights. Anyway, he rants about all kinds of martial arts.
For example he says that karate, taekwondo, ninjitus, wing chun all suck and don't work.
Is he right or just talking nonsense? Why should taekwondo not work for self-defense? TWD has really crazy
kicks. Why shouldn't this work in a fight?!
Stuff this guy "recommends" is: MMA, Jiu Jitsu, Boxing, Kendo, Muay Thai
The thing is I don't want to do a martial art or a self-defense where physical strength basically determines
who wins.
I also don't really want to do something like Muay Thai where you can expect to get a lot of hits to the body and head. I am worried about injuries. Especially injuries to the head are very dangerous, just look at the professional football players....
But on the other hand, how can you toughen up and prepare for a fight if you never take any hits??
He recommends Kendo? To be fair I'm not particularly familiar with it and I honestly don't know if it combines empty hand techniques, but it's sword fighting at it's core. Does he recommend you walk around with a katana for self defense? I don't think that's really practical unless your last name is MacLeod.
If he's recommends you walk around with a sword, then I'd say he falls closer to the nonsense end of the spectrum. I'm far from an expert, but any martial art can be used for self defense. But there seems to be this misconception that training in martial arts (especially if you find that "right" one) will make you invulnerable. No martial art will. And quite frankly assuming equal skill, the bigger stronger person is going to win a fight 9 times out of 10. This is true across the board and there is no special secret fighting style that will negate it. That's why there are weight classes. This is especially true of martial arts (in my opinion) like MMA, western Boxing and Muay Thai (which I've all done BTW). You're likely to stand toe to toe with someone just because the nature of the techniques. That being said, most people who might attack you probably aren't trained in any martial art and skill can trump size and strength.
As I said use to train MMA, western Boxing and Muay Thai. All of which I enjoyed, but I stopped because I too was afraid of getting injured. The gym I trained at catered to young guys who had aspirations of competing at the semi-pro or pro levels of those sports. If you wanted to progress beyond just the basic classes and spar you needed to prepare yourself to spar those guys (and I did for awhile), but since I'm a woman with no interest in competing (at least not at that level) and I have a day job, it wasn't worth the risk of being hurt for me. Other gyms in other areas may be run different ways and have students with different goals.
I would say that it probably is a good thing to spar hard to the body at some point just so you know what it feels like to really be hit. That being said, you cannot condition yourself to be able to take hits to the head no matter what you do. So, yes hits to the head are dangerous. You have to decide what injuries you are personally willing to risk.
I left MMA and Muay Thai because that school was more than I was willing to risk. I did miss martial arts though so I recently found a traditional Karate (Isshinryu) dojo to train at. I find they teach practical techniques that could be used in self defense (in many ways more practical for someone my size and strength). Sparring is light body contact and no head contact, although the instructor will let higher ranks go pretty hard to the body if both people are okay with it. I still get bruised up, I'm sitting here with ice on my shin from a guy blocking my kick with his elbow, but I'm not worried about concussions.
So that was a really long way to echo what others have said, train what you want. If you like TWD, then train that. If you like MMA, or Boxing or Muay Thai then train that. Unless you're a LEO, in the military, or some other similar profession martial arts should be a hobby you enjoy. Yes, it should teach things that can be used practically in a fight. But honestly when people tell me they want study martial arts just for self defense and no other reason and they need to find the most effective one (assuming the aren't in one of the aforementioned groups), I just wonder about their life choices that they're putting themselves in situations where they get into fights on a regular basis. Because I'm sure the vast majority of people that practice martial arts never use them to defend themselves, because they never have to. And it seems like a lot of time and energy to put into something you don't enjoy that you may never use.
