yoga on main street
which martial art is suited to my build?

ok i know this is a rather awkward question to ask, i i know that many people claim their martial art to be the best / most effective, without even hearing out the aims of others. So here's the info.

I'm 5'11 / 180cm
168lb / 76kg

I would probably say i'm a medium build, quite broad shoulders.

Currently i'm planning on taking up Yoga as a means of supporting my martial art choice for flexability, as well as to aid with my posture (i'm a computer geek)

The main reason i want to learn martal arts is self defense, and fitness, which in my opinion go hand in hand, if somebody were to confront me on the street, i'd be happy enough to get in a quick distraction blow and then peg it out of there.

If you want any more information on my build etc then i'd be happy to provide it. The last martial art i think i did well in was Thai Boxing, but i'm not sure if there's anywhere in southampton (england) which teaches it.

Ok... so i look forward to your answers

I've done many different styles of martial arts and I've found that there isn't one style thats good for certain build. However, there are moves that work better with one build than the other. Depending on the style of martial art you want to do.
For stand up, Muay Thai, Tae Kwon Do, or Karate would be great for you. If you have a longer abdomen, I'd go with Karate. If you have longer legs, you'll be great at Tae Kwon Do. If you are even in both, You'll be great at Muay Thai.
(I have unusually long legs, so I'm really good at Tae Kwon do)

For grappling, I think you'd be great at Jui Jitsu. (I'm not vouching for any particular kind.) But Graci seems popular in these forums.
I wouldn't recommend Aikido or Judo because they're both derived from Jui Jitsu and were dumbed down as to not hurt people. Since you're looking for self defense, I think you get the best of both of those in Jui Jitsu.

I would also suggest Western Boxing. It's actually really good on the streets since you don't have to lift your legs and risk a miscalculated fall. Also, since you're in England, fencing is a great martial art. The lunges in fencing can compliment most stand up martial arts to cover distance between you and the opponent.

I would suggest that you find couple of local martial arts schools and go take their introduction classes. Most schools offer these classes. It's a day or two to get to know the martial arts and decide whether you like them. I've learned that sometimes the school itself and instructors make all the difference in the kind of martial arts you like.

I hope all the information helped and good luck on your journey!
