BERLIN, N.J. (WPVI) -- Slide to the right and check out the workout sensation from South Jersey that's sweeping the internet.
They call it Cha Cha Plank.
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!
