I have only practiced Taekwondo and Aikido. I Did Taekwondo for about 4 years and was about 4 to 6 months away from obtaining a black belt when I left. I later on, did Aikido for a few months (I think about 3 to 4) and enjoyed those classes much more, although I wasn't able to keep going, because it was a college club and I wasn't a student yet at the time.
