When I was looking for my son I was thinking of more or less the same questions, but here is my 2 cents. Be realistic in your ambitions. No one can turn into a black belt in a year. It takes time. Just remember that you wont bust out moves like you see in the movies as learning it and applying is two different things. Taekwando, Kung Fu and Karate are popular and in theory should all help in development on daily self defense techniques. There are other options, and are full contact but they will be more difficult and you have more possibility of hurting yourself. Martial arts is not like driving, so let me be clear, there nothing is easy. If it is easy , then IMO its a waste of time. Dont worry much if you are slim. I noticed that it is better if you are slimmer as it takes less time to start getting your muscles to do streches and excercises. Dont worry about performing, people of all ages and sizes have progression. When chosing a school here is what you need to consider: - How much time does a coach spend with each student - How much time does the student actually sit down and do nothing - Class size and coach to student ratio - Experience of the coach - First interaction with coach. Try to guess if they are in it just for the money only. a) usually a trial class is free if not then I would avoid. b) I had this guy who presistently wanted me to join with my son as well giving me lots of discount. He sounded like too much like a sales men. c) if they stress too much time on theory Hope this give you an idea - See more at:
