I would like to start a martial arts program, but not sure what would be best to begin from the ground floor. I need something that would be easy to learn, yet effective in self defense. What are some good styles I could try as a beginner? I am also not as fit as I used to be. My boyfriend is a red belt (is it red right before black?) in Hapkido and his school is a part of the International Hapkido Federation.
