I be go to repeat what other reviewer have say . I have no intention on add fame or defame this product . again , like what the other reviewer have mention , I be skeptical of this product at first , but I decide to give it a try after try it in Modell 's . the 6 minute dvd exercise be good . it really do give a workout on my muscle , you can feel the burn after the first minute of use it . I hope this product do not injury my back , though . if anything , I will come back and tell you guy about it . all in all , it be a great product and I do not mind use it at all . there be nothing funny or embarrassing about . EDIT : 8\/18\/10 I have be use it everyday . I do not experience any neck , back or muscle pain . I like the `` burn '' every time I use it . great product !!! EDIT : 10\/03\/10 I still have it , I be still use it , still in a good shape . I do not see any large change in muscle mass but I do not really care !
