Query: wonderful

after using this tape for only a few days, i could already feel and see a difference. i already have a fairly athletic body, but its hard to stay in shape over the summer. i've only used the first 10 minutes on this tape, just because im so thrilled with the results on my stomach. this is definately worth the 10 bucks. give it a shot!!
