Although the exercises are different from the traditional and original Shaolin Yi jin jing (sinew transforming exercises) the book loses very little in the content of exercise benefit. I have purchased 'expensive' books in the past on Chi Kung and was left very dissappointed, so it was a pleasent surprise to purchase a 'cheap' book and found it rich in information. This is an excellent book for anyone seeking better health but for the most part a great benefit for martial artists who are seeking a good 'all round stretching and strengthening' exercise routine, as it can be done as whole set or one can draw on individual exercises to 'infill' an incomplete personal programme.
