Title: Not necessary for abs
Review: This book first of all is expensive. It teaches you positons those you won`t need at all to strength your abs. Never use called Wheel(as he recommends in the book for not using because of back pain) means not tested and used before but just to add volume to the book! I experienced back pain as well after first use of this wheel. They sell those kind of rubish (wheel) on (as seen on TV) as well. Don`t buy this book! I do sports and a martial art for along time and read many books about sports.
