Ok, new silly question, silly question =)
Why general population want to have a 6-pack abs?
You don't need a clear 6-pack to have a strong rectus abdominis muscle.... Also when i think about it, it's quite useless, unless you learn martial art and need a strong muscle to protect your stomach. Then unless you like swimming or walk around shirtless, it's not visible most of the time anyway
My biggest guess is because it's one of the milestone for people to achieve (much like dunk in basketball)
