I be skeptical of whether or not the product would measure up to the hype , and I be pleasantly surprise . I see result after as little as a week . I have be use it for a little more than a month now , only do the basic six minute workout and the definition and muscle gain have exceed expectation . at first , the exercise be a little difficult but the more you do they , obviously the easier they get . for as much effort as you have to put into it , you get more than double the result . I know this be a little redundant but I be always concern about review and I want this one to really assure you . for the price , I would definitely buy it again , if I ever have to .
