This is a three minute video of a group of eight firemen from a Jinshan District fire station in Shanghai, China, demonstrating their very impressive synchronized jumprope skills. They manage to make a total of 577 jumps before somebody screws it up. For reference, I’m usually good for about a dozen jumps before I feel like I’m going to die and yell inside to my mom to ready an emergency glass of Sunny D before I pass out. “How are you still alive?” That’s the first thing my doctor always asks too. You know what I tell him? Healthy eating and exercise. Then we both laugh so hard I almost die right there on the examination table.

Keep going for the whole video.
