This is the best book on Traditional TKD, or Katate I have ever seen. Keep in mind, this is not Olympic style TKD of the 21st century, this is good old solid Ji Do Kwan, Tae Kwon Do. Master Cho covers things in this book that show TKD to be the "art" it is. Anyone can do the things in this book. It just takes time, and practice.
This book also shows that TKD does indeed have good, solid hand techniques, and defenses.
This book is NOT magic, and do not exspect any "tricks" to make you a master overnight. Master Cho has given a lot of information, and it works. All you need to do is practice!
Get the book!

Aunque no sepas mucho el ingles podras entender el libro, ya que tiene suficientes fotos bien esplicadas de cada tecnica. El maestro y autor del libro es muy bueno, yo pertenesco a su federacion de TAE KWON DO.
