You do the whole line dance from the popular "Cha Cha Slide" - while planking on hands and feet.
Dan Baldwin is the genius behind the "how to" video that has more than 20 million views and counting.
He's a personal trainer at Anytime Fitness in Berlin and he's challenging people to give it a try and post their Cha Cha Plank video to Facebook.
Because the song is 3 minutes long, Baldwin says do what you can, build on it every day and remember you are stronger than you think!
