Query: IT REALLY WORKS!!

This is the best investment I have made towards losing weight and feeling great. It really truely works. I have tried diet pills, fad diets, everything. But this video shows results within 10 days. I noticed results by the end of the 1st week. I have lost 12 pounds in a couple months. My arms, legs, abs, back are toned. I get complimented on it all the time. The resistance band really works. HONESTLY you should by this video.As for the comments on drab setting and music. Here is my recommendation. Do what I do. After you get the hang of the routine and all the moves down. Put the TV on mute and blast your own music to get you pumped. WORKS for me! It will work for you! I lost 5 inches off my waist line.
