Just as with any kind of fitness program that promises a better, well-toned body, some will never be satisfied with the results or never get any results at all. One reason why people shy away from the Truth About Abs diet is the fact that this is not designed for everyone. This abs training program requires individuals to sweat everything out by doing all exercises religiously while adhering strictly to the recommended meal plan. This workout program is not an overnight fix—it does not promise to give its readers rock hard abs in a snap. Unlike other exercise routines which focuses on a variety of crunches and sit ups, this guide promotes a more difficult set of exercises that is why this is not ideal for those who get tired easily and has physical deformities. In addition, for people who are fans of crazy abs equipment, this workout guide will definitely disappoint them, as it does not promote the use of such machines.
