Especially the stretching exercises are very difficult to part. Since I am very inflexible innately, but I can confirm that the exercises can be performed for little people articulated. The meditation exercises have less to do with spiritual with yourself-but do un are hassle free to get through everyday life. The individual Punshes, Stands and Kicks are sometimes complicated, however, go through constant repetition in flesh and blood. What I like so much about the book that newcomers get here a very good introduction to the Shaolin Kungfu. How much of this book will help advanced, I can not judge. For me it's perfect. Because the quality is right (thick sides, sharp images), I find that the price is a joke and give it 5 stars. PS it's written in a very simple and clear English.
