People across China are taking part in a strange form of exercise: walking on all fours.
The craze – which has spread like wildfire with the help of social media – was born when a group of students in Beijing were seen crawling around in circles in a playground last month.
The exercise has been inspired by the movement of animals like cats, crocodiles and bears. It is not only fun, it is good for your health too.
"Encouraged by my friends, I had a try today and crawled for seven minutes," one student says. "My cat might have been scared by my hidden skills when I chased him on all fours!"
