st i won my first two MMA fights with some muay thai training and Judo as my base. won both of those fights predominantly b/c of my Judo training. it's a sport with a lot of carry over into self-defense and fighting.
I'm always impressed with this video. Do you know if she was a Judo student? Even if she wasn't she learnt a lot of techniques to make this. Some of it looks a bit like old school Gracie Jiu-Jitsu self defense (In my opinion. I could be very wrong.)
