The latest viral video to make the rounds of social media makes absolutely no sense but it will make you want to try it.
The ‘chair’ challenge which was first uploaded to TikTok sees people trying to stand up whilst holding a stool or chair to them, which doesn’t sound that strange on a whole.
The thing is though it seems that women can do it but men can’t.
One couple Krystyna Sorrentino and her fiancé Devin had a go of their own go to prove the challenge.
The challenge requires that you stand two-steps away from the wall before bending 90 degrees and placing your head on the wall.
You then place a chair or stool underneath and try to stand up whilst holding it.
Krystyna, 32 managed to do it perfectly and on her first attempt without a struggle.
But her fiancé Devin does not do it quite so smoothly, as he becomes stuck whilst trying to stand up and ends up stumbling across the room.
Krystyna explained that when Devin stood and concentrated he did eventually succeed.
And they aren’t the only ones to have a go, with many posting there own videos on Twitter.
It turns out that there could be a couple of reasons why women can lift the chair easier.
One scientist from the US, Jeremy Johnson wrote in a blogpost: “Interestingly enough, many girls can successfully complete this challenge, while most boys cannot.
Jeremy explained that a difference between the center of mass in males and females is the reason behind the difference.
“The center of mass for most girls is lower to the hips, while the center of mass in boys is much higher. Therefore, for most girls, the center of mass while bent over the chair is above their feet, while the center of mass for most boys is above the chair.”
Another explanation came from Professor Brian Ford at Cambridge University who blames the size of men’s feet for it.
He told The Sun: “Men have longer feet than women. Two paces back for a man would be some 60cm, for a woman it’s more like 50cm.
“So to begin with, the man is forced further away from the wall.
As men are further away they are forced to bend forward, making it harder to then stand up.
