Martial arts are very good to learn and even more when you are small and you are interested in learning this type of sports that are very useful for the visa also as long as what you learn is always used for defense, I agree that you can learn only a bit of martial arts by yourself, such as reading a book or watching videos, but it is always good to have or pick up someone to teach us and help us improve our skills and movements and thus develop them more at the same time.
