Firm and Flatten Your Abs by David Grisaffi is more of an abdominal training encyclopedia than anything else you might expect from this powerful ebook.

Without going overboard with what it doesn’t provide, I am going to tell you why this may or may not be a good investment depending on the type of training you require.

Firm and Flatten your abs contain two principles;

1. Ab workout using Core Abdominal Exercises that you have never seen anywhere else.
2. Diet and nutrition techniques that will boost your metabolism to shred that fat off your belly.

Here are the facts on why Firm and Flatten your abs is a good investment.

Diet and nutrition plays an 80% role in total body fat loss, and David Grisaffi has successfully included this factor with effective techniques in this Ab training ebook plus some great diet features in his bonus book, Modern Diet Secrets Revealed.

Unlike other fat loss training guides that I highly recommend (The Truth About Six Pack Abs, Turbulence Training, Fat Burning Furnace), David has failed to go in depth into the importance of total body strength training that is actually a major key in your goal to get flat abs.

There is no doubt you will see great results just by following the 7 levels of Ab Training and the diet principles specified in the Firm and Flatten Your Abs manual, but I suggest you perform at least 3 days of High Intensity Interval Training to get results much faster than you would simply by following the main manual.

It is also a great idea to add strength training into your workout routine by incorporating multi joint exercises like Squats, Lunges, Pushups, Chinups, and Pullups etc… that can create a great shock in your metabolism which means faster fat loss aka a shortcut to getting flat abs.

Firm and Flatten Your Abs in my opinion is a bible of abdominal exercises. I would not rely primarily on this book to get flat abs. If you by chance have a bad back problem or any other physical injury that maybe preventing you from performing hard exercises, then this is the perfect blueprint to get you flat abs.

With the diet techniques and the core training routines in Firm And Flatten Your Abs manual, you are guaranteed to make your back stronger, lose total body fat and get flat abs in no time although you would take a little longer than you would if you follow a complete total body training like The Truth About Six Pack Abs.
