I agree with the other review ... this work great ! my upper arm have become more and more flabby over the year , and within just a few week , I see a shocking improvement . I also do the 6 minute workout daily -lrb- because of the positive result , I be very motivate to keep do it -rrb- , and mostly while watch tv , since it be a easy routine to remember . I also take it on vacation with I , since it do not take up that much room . I have see the absurd comment about it be suggestive , but honestly , do not most excercise look silly when you be do they ? this work great , and I be convince to buy it because the main site offer to not only return the purchase and shipping price , but pay for return shipping if you want to return it .
