Jumping on the cardboard beds of the Olympic Village to test their strength has become a new sport among Tokyo 2020 athletes, after speculation that they were "anti-sex" beds.

Some Olympic athletes, subjected to restrictions due to the Covid-19 pandemic that prevent them from leaving the village except to compete or train, have entertained themselves by jumping on the beds, which are made of recyclable cardboard as part of the organizers' plan to reduce the environmental impact of the Games.

The latest to test them were members of the Israeli team, who filmed themselves climbing one by one onto a bed and jumping until nine of at once them broke the structure.

Baseball player Ben Wanger recorded the video and uploaded it to social media where it went viral, and has since been taken down.

The destruction of the property has sparked anger in Japan, according to Japanese media.
