I be a register nurse , in excellent health , exercise on elliptical trainer regularly , be able to follow direction to the letter , and STILL get a very serious and costly injury directly related to the use of this product . my job be to educate my patient on the use of various product to maintain they health and well be and I feel this product fail terribly in it be education to the user . there be the standard disclosure to check with you doctor before start any exercise program but they fall short when it come to actual use of the product . I have since find out that you should never begin exercise of you upper body with this much weight initially and a gradual increase to allow you muscle to build up be absolutely require for all exercise program . the Shake Weight do not allow for gradual increase and due to this it be a dangerous and potentially harmful product . I , for one , will be follow up on it be continue presence in the marketplace and will hopefully have it remove from the marketplace to prevent further costly and painful problem to the consumer . nurse educate but we also protect the public safety and I feel it be necessary for I to step up to the plate and see to it that a product that be injurious to the consumer be remove from public consumption .
