Can you teach yourself karate

Answer 1

It is pretty hard to teach yourself something you don't know. And it is very difficult to learn something without a good teacher. There is no substitute for working with a qualified instructor. While you can learn some of the positions and some techniques from books and video, you are only learning some martial skills, not a martial art.

Answer 2

The hardest part of karate is showing up for class on a regular basis. Keep doing that and eventually you will earn a black belt and become an accomplished martial artist.
