If you think everything has been said about tight bellies, a new 'trend' suddenly appears:the ab crack.
The what? An ab crack is a vertical line of visible muscles running from your breasts to your belly button. The line appears mainly when you are well trained, but a little talent helps.
Whether the ab crack is the new six-pack or not… We let the trend pass us by. We find a balanced lifestyle and feeling fit and healthy more important. Whether with or without a six-pack/ab crack.
