I tend to agree with the theory that the width of the waste has something to do with the potential to see a six pack type stomach. My wife has as little stomach fat as is womanly possible and she has zero six pack definition. Whereas I can be 25% body fat and still see a six pack. Genetics seem to play a big role in the visibility of the striations.
