Everybody Prance Now! Celebs Jump on Board the Prancercise Dance Wagon

Psy's horse gait has nothing on Joanna Rohrback.

By now, you've probably seen video of the exercise sensation that's sweeping the nation (well, at least this week) called Prancercise. A clip of the horse-inspired fitness workout went viral and even has celebs taking notice.

OK, so maybe Prancercise is a bit of a joke. But it's a joke that Rohrback, its creator who is a retired social worker and real estate agent from Coral Springs, Florida, is clearly in on. Now she's prancing her way to Internet celebrity status.

So, which celebs are hopping on the Prancercise bandwagon?

Kelly Osbourne tweeted that she's gonna start doing it herself in the mornings:

Sally Jesse Raphael is thinking about trying it out as well:

Sophia Bush, Nina Dobrev, and Virginia Madsen have all re-tweeted about it.

But our favorite tweet so far is from World of Wonder productions, the company that produces "RuPaul's Drag Race," which reminds us that RuPaul herself was also an early adopter of prancing for joy, with a song from 1993:

RuPaul vs. Johanna?! Now that's a "prance off for your life" we'd like to see!

Rohrback, 61, was on the "Today" show Friday showing hosts Natalie Morales and Al Roker how to do the fitness craze she invented last fall.

Savannah Guthrie seemed to be a bit jealous that she didn't get to participate in the gentle workout, tweeting:

"Omg! Insider" caught up with Rohrback in NYC on Friday morning, who revealed why she believes so much in her self-created craze, and even taught the show's summer interns how to Prancercise.

"It just started growing like a volcano then exploded!" she said of the past couple of days. "Like going into The Twilight Zone — swept away here, swept away there — I don't know who I am, where I am anymore."

She explained that by definition, "Prancercise is a springy rhythmic movement forward similar to a horse gait, ideally induced by elation," and added that Motown music often can work best to get the gait going.

Count us in!

Rohrback launched Prancercise in 1989 and it took her five years to perfect it. By 1994, she had created the unpublished manuscript for what would eventually become her book, "Prancercise: The Art of Physical and Spiritual Excellence." According to Rorhback's own book description on Amazon, "This book is a true literary resource well researched and documented, not just propaganda. It's a recipe for fitness, health, and self-fulfillment!

But it was her YouTube video titled "Prancercise: A Fitness Workout," created in December of last year (which coincided with the publication of her finished book in hardcover), which lead to what would become this week's viral breakout. The video has skyrocketed from obscurity to having over 2 million views since Thursday morning. Searches for the hot exercise trend are through the roof on Yahoo! — up 2,669% in the past 24 hours alone — making it one of Yahoo!'s top trending topics Friday.
