I am designing a short seminar on basic self defense/violence prevention for school age child women. Does anyone have any suggestions and/or reference material. I was originally planning on teaching some simple/effective American Kenpo techniques but after some thought decided that would be ineffective in the long run due to the audience and time constraints of this type of program. I would like to give the women a good set of mental tools along with a set of physical tools that they could realistically use with very little training. Any help with this would be great.
