I won't waste your time with bull.
You want abdominals? Those showy, model abdominals?
Well, those are made in the kitchen. Sorry. Buy "The Metabolic Diet" by Mauro Di Pasquale and lose that spare tire. Also, take a look at "The Russian Kettlebell Challenge" (also by Pavel Tsatsouline) to lose fat and put on muscle at the same time.
You're still here? Oh, I see. You want ABDOMINALS. Not JUST showy, model abdominals, but abs that can stabilize your core with no belt when you're deadlifting 500+ pounds, abs that can take that ham-fisted brawler's hand and laugh it off, abs that are good enough to do circus tricks with, abs that you can build in your basement with less than ten bucks worth of equipment? (Or no equipment at all?)
Pavel's the man that you want for that job, and in this book he tells you how to build a world class midsection capable of these feats and more.
He explains where the conventional thinking on abdominal training in the US went wrong, and why training his way is better. He'll teach you how to make your abs and obliques into "team players" so you can throw farther, punch harder, and drive that golf ball like you've never done before. Moreover, he teaches you "forgotten" midsection breathing techniques and high tension techniques from martial arts that will make all the difference in your abdominal training.
The one thing--the ONLY thing--I don't like about this book is the eight pages he spends hawking his "Ab Pavelizer". I wouldn't mind it so much if he showed you how to correctly perform the Janda situp with a partner, as well, but he doesn't.
The upside of this issue is the website featured in the book. Pavel (or one of the other "comrades") will be happy to tell you how to perfrom the Janda situp correctly. The "tech support" for all of his products is awesome.
I give this product five stars because, if you're like me, you know all of the conventional theories on ab training, you've tried them, and you haven't gotten anywhere. (Or at least not as far as you've wanted to go.) Pavel shows you how to break through that barrier, and he turns all of your previous knowledge on the subject into "superknowledge"--because you can combine many of his techniques with other things that you already know.
Pavel's training is on an entirely different level than 90% of the training literature out there. I can't reccomend his books highly enough.
