1. What styles do you do? I currently do Ninjutsu (Bujinkan) - although my classes aren't actually running for the time being, BJJ and am starting judo next week (hopefully). I have done Muay Thai, Capoeira and Iaido in the past. 2. Did you pick your MA style(s) because it (they) advertised self defence capabilities? Yes for all of them except for Capoeira which I picked because it was a great workout, looked cool and was fantastic for bodyweight strength and control and Iaido which I studied for the sword work and because I found it very relaxing. 3. Did it (they) actually teach you any self defence stuff? Yes, the Ninjutsu does, the Muay Thai did, the BJJ will and the Judo hopefully will. The Capoeira and Iaido didn't. 4. Do you do multiple styles because each one offers different things? Yes (see answer 2 for Capoeira and Iaido). Ninjutsu covers multiple aspects from unarmed to weapons work (part of the reason I picked it was the weapons work which I love) to survival and outdoors skills. Muay Thai was great for fitness and stress relief as I got to hit things really hard! BJJ and Judo will allow me to really concentrate on my throwing and ground fighting skills.
