It's a good book for self defence.Do the moves fast!This book shows you alot of kicks. First I recomend you should get the ``Tao of jeet kune do''By Bruce lee. Then decied what fighting style you want to learn. Every style is about the same. That is the good part of it and bad part of it.No style is better then anouther style it's up to the individual. There's too many factors that could turn in a fight!Nothing could be perfect in a style because as human beings we are not perfect so what we make isn't perfect either. In this case fighting styles!
