I want to learn how to fight or at least defend myself in a street fight. I realised having all this muscle isn't much good if I can't utilise it. I know a little bit of boxing, but I want to learn a martial art of some form so I can have a greater advantage. There's a krav maga class near me I was thinking of checking out but I've heard conflicting opinions on whether krav maga is actually useful or not.
What martial arts are best for self defense?
