Harrow Aikido

Aikido is a reletively new Japanese Martial Art. It has it's roots in Ju-jitsu so it has some similarites with Judo without all the hip throws. It's a defensive system so there's no emphasis on punching and kicking and because it relies on being in the right place at the right time, can be taught to almost anyone. Physical size and power for example are much less important than being nimble.

The aim is to evade an attack and position yourself so you can re-direct it's energy into throws, joint locks and pins. This makes it a great choice for everyone, regardless of size or gender, as you are not trying simply to match force with force.
