3. Does it fail to mention diet or nutrition? 
Nutrition is such an integral part of losing inches, building muscle and dropping weight. If a product or fitness program doesn't address the nutrition side of the weight-loss equation (i.e. a reduced-calorie diet), then you can pretty much guarantee that it's a gimmick exaggerating its results. All the exercise in the world will not change your body if your diet isn't also in line with your goals.
