Description:On July 10, 2025, in Gansu, China, @Liànwǔshù shared a video of a training mishap during resistance running. In the video, one student runs with an elastic rope around his waist while another holds it to create resistance. When the holder loses his footing and gets dragged forward, the runner comes to a stop. Suddenly, the rope is released and snaps back, striking the runner painfully on the butt.
