It’s a battle of the sexes that’s taken over TikTok! In the viral “center of gravity challenge,” or the “balance challenge,” a man and woman start off on their knees and elbows, then try to quickly put their hands behind their backs without falling. But one person always seems to win: the woman! Meanwhile, men keep eating the floor as they lose their balance and fall on their faces. It turns out that the science behind this says that women have a lower center of gravity, giving them an edge.
