I make fun of this weight when it first come out because the workout look ridiculous , but then i research into the product , read many rave review -lrb- and many also claim it be a ridiculous look workout but that it work !! -rrb- and how this thing have work for they . I like work out but my busy shedule limit I from do hour of workout so with this 6 minute workout i can fit it right in before i go to sleep . I feel the burn and my muscle be sore the follow day . I will come back and review this again after a few month to tell of the outcome of this product and how it have work for I . but so far this product be do it be job .
