It takes bits and pieces from several.
A little bit Krav Maga and a little bit Kung Fu, what's the remaining 98%?
Can't personally think of a mixture of the 2 but you can learn both in the UK. Google free krav maga seminars UK and see if you can find free krav maga lessons in your area.
Krav Maga is already having techniques that are to be found in Kung Fu (Chinese martial arts)
So what you seem to be looking for, is already in Krav Maga.
What you want to train is completely irrelevant. No one cares. The only thing that matters is what is available near you. Even if you find that weird combination, which I highly doubt you ever will, what are you going to do if it's a 3 hour drive from your home?
Not really. You could learn both or integrate the other into the other style.
Learn both.
Hey! I'm just wondering is there a form of martial art which is a little bit Krav Maga and a little bit Kung Fu..try and find one similar to both and if you can take lessons of them here in the uk!
