In Combat abs, Auther Matt Furey focuses on 50 exercises that are done with almost no equipment other than your own body. Many of these are isometric but all focus on building firmer, stronger abdominals. The exercises are broken down into beginner, intermediate and advanced and the book starts with The Magnificent Seven, a series of basic exercises which the auther suggests you do to start each day. The strong points of the book are the exercises, most of which can be done in your own home without special equipment. Some of the advanced exercises use special equipment. There is a lot of self propaganda in the book where people rave about how Furey changed their lives, and the author hawks some of his other products. He also gives you a list of things not to eat but he is not a nutritional expert and should not do this.
