I'm 17, quite small, 5'3 and 120lb, I would like a system where my size is not a disadvantage. I'm traveling to quite a dangerous part of the world in 18 months, and I would prefer an art that can teach me real self defense against attackers. Apart from that I want to pick up a martial art for fitness, and for fun! I live in a city with lots of different clubs, so I have so many options to choose from! I was thinking maybe Aikido, but would it be practical in a real life situation?
Any suggestions? Thank you.
Also, I would have liked to do Krav Maga but they don't take under 18s
