Any one you choose will take time to learn how to use it correctly and effectively. There are no short cuts. Find a good school and stop trying to find an art. You can find a krav maga school, boxing gym, etc and the instructor is bad and it won't be worth going through the door. It would be pointless. The instructor makes the biggest difference not the style or in the case of somethings you mention sport. There is a hige difference in competing and self defense.

Kickboxing is a sport, Boxing is a sport. Krav mage is not a martial art. It is a self defense course where you learn a a few techniques taught in martial arts.

If they broke into your home or attacked you today or net month you probably will not have learn enough to defend against any attack. I have had students that had to use the little bit that they had learn after one lesson and they were effective. But that is not to be expected. Some students learn faster than others.

You already think you know, so don't ask. They are all effective for self defense. If you like Krav maga and Kickboxing then do those. Don't ask if you only want answers that you think are correct.

First of all, there is no such thing as best self defence martial arts.

All martial arts are equally effective for self defense when used appropriately.

In my opinion, if you are up against a robber, you would wanna take him down as fast as possible with minimal effort. The longer the exchange of strikes/blows, the greater risk you have.

I would suggest either Boxing/Kickboxing. Muay Thai is also a form of Kickboxing.

Why ? Because in Boxing/ Muay Thai, you learn to throw proper kicks and punches and execute it on heavy bags. You instructor will do padwork with you as well. Heavy bag work trains your power while padwork trains your speed and accuracy.

When it comes to facing a robber or get caught up in a street fight, you would want to bring the guy down in one blow. Whichever you learn in Boxing/Muay Thai can be used to bring him down in one single blow with proper accuracy and power.

Bruce Lee once said "I fear not the man who practised 10,000 kicks but the man who practise the kick 10,000 times."

Any martial arts with enough practice is deadly.

Please don't insult to martial arts. Judo, TKD, kung fu and all are effective. Can you knock down a TKD guy ? No. You will end up with fu**king bloody face. Martial arts not for fu**ERS like you. You will die from a thug's attack. It should be for a fu**ker like you.

You never learn a martial art. Good luck.

Tbere are lot of robberies taking place in my neighbourhood at nigh and I keep hearing thugs breaking into people's home and beating people and stealing things.

I'm scared that robbery could can in my home someday and it's unsafe at night to travel

So what martial arts can I learn for self defense?

I don't want to learn tae kwon do or kung fu or judo because I think they take too long to learn. And are not good or effective in street fight situations to protect myself! Should I learn boxing kickboxing or krav maga?
