Mine will only show up when I flex, for most people to have your abs start showing you need to hit around 10% bf.
They come in well without flexing at around %8 or so
PulseDriver: I hear ya man, I have good abs, but I could have great abs if I cut my cals and shed water. I dont want to loose my size though, so I try to keep it at a decent balance of being lean and being big.
Its really a fine line that many people will never be able to stay on %100. It took years for me just to understand how much calories I should be eating and at what times. Everyones body is so differant its very difficult to use general information for the most part
