Query: truly awful

The main problem with martial arts?: People trying to teach things that they are not qualified to teach. This book falls squarely into that subject. Soto has no real background in any martial arts so he isn't qualified to teach some new "style" that he created. Book is worse then other reviewers have stated. It is so bad that I am not trading it in at the used book style but rather I am shredding it so that it can be recycled as something else. Waste of paper and time
