Sooo The Belly Button Challenge Is A Thing...

A new craze involving a simple test to show how good your figure really is has taken China by storm.

The challenge has seen thousands of people post selfies to show whether they can touch their belly button by reaching around their backs.

A hashtag which translates to ‘reach your belly button from behind to show you have a good figure’ has been accompanying the photos.

But don’t worry — if you can’t accomplish the pose, it’s not because you’re not thin enough.

Your ability to achieve the belly button challenge is actually related to your flexibility and arm length.
