The ab rocket is INCREDIBLE!!!!!!!...you will see abs in just 1 week. i did it and my abs are tight and lean. Its great for any age. My 13 year old brother has abs like crazy. Im going to keep trying and report my results.
well if you are male you body fat percentage has to be 11% before you show abs and females have to be 14%, so work that out over the internet then you will know now much you need to lose, also don't work out everyday otherwise your muscles don't havwe time to repair themselves and get bigger.
