We're an increasingly health-conscious generation and I think we all, to some extent, try to keep up with the latest fitness regimes and body trends. I'm not saying it's a bad thing, but in extremes, it probably isn't particularly great either. And this disturbing new body trend can potentially push the most trend-vulnerable among us to the very limits.

According to Elle, the 'ab crack' is the latest body-image-crushing trend that's taking the fitness world by storm. In case you were wondering, it is exactly what it sounds like - a vertical crease that appears on uber-flat stomachs.

This is what the world has come to, I suppose. Turns out nothing says 'I go to the gym' like an irrigation ditch down your front.

With a host of fitness models flaunting theirs, the ab crack is well on its way to becoming the next thigh gap.

If you're wondering at this new extreme of fitness, 'where do you draw the line?' the answer apparently, is 'right down the middle of your rock-hard torso'.
