I did MMA when I was younger, haven't messed around with anything except punching the bag in about 2 years.. During MMA I trained boxing, BJJ(no gi), and kick/thai boxing (hips are bad I can't kick well). Also, takedowns/trapping if you want to count that.
Did a couple knife defense classes which were really fun.
