A new body challenge has emerged in China following the popularity of previous contortion tests, with the latest relying on flexibility.
The "reverse praying" trend sees users uploading photos of themselves to social media with their hands clasped in a 'prayer' position behind their backs.
It is the latest craze
of its kind following the collarbone challenge in which Chinese women attempted to hold a stack of coins in their collarbone but only after 300 million people tried to touch their navels from around their backs - to showcase their slim physiques.
The new physical challenge appeared on China's popular microblogging website Sina Weibo this week and like the belly button challenge, the new "reverse praying" posture is about how flexible the body is.
Most of the participants have been young women who took the opportunity to show off their flexibility by holding their mobile phones between their palms.
