Unlike most of the social media challenges that emerge, this is one that you can actually try at home without risking your life.
A new internet craze has emerged and all it involves is touching your belly button by reaching behind your back and around your waist.
The belly button challenge originated in China where thousands of people uploaded selfies of them with their hand wrapped around their waist.
The posts were accompanied by a hashtag, which translates as ‘reach your belly button from behind to show you have a good figure’.
It is trending on Weibo, the Chinese equivalent to Twitter, and has received more than 130 million hits since yesterday – but it has also got the Twitterati taking up the challenge.
Given the likelihood of you having already attempted to do it yourself, don’t despair if you come nowhere reaching your waist.
It appears that someone’s ability to achieve the belly button challenge is not down to one’s tiny waist, but rather a range of factors including flexibility and arm length.
A photo uploaded by a more curvaceous male blogger touching his belly button took Weibo by storm.
More than 2,600 people ‘liked’ his effort, with one tweeting ‘You go Buddha! Show the skinny girls how it’s done.”
