Prancercise: Everyone's doing it. Well, they're not prancercising as much as they're, say, giggling at the instructional video and itching to find out more about its creator, Joanna Rohrback.

For those of you behind the ball, this is prancercising:

According to the official YouTube video, the technical definition of Prancercise is, "A springy,rhythmic way of moving forward, similar to a horse's gait and is ideally induced by elation."

Yes, it's hilarious. And, yes, Rohrback knows you're laughing at her more than you're laughing with her. But, she's been so busy scrambling to fix her website (the heavy traffic crashed it on Wednesday) and turning down interviews (she's been so bombarded with requests that she's, "going wacko") to care.

With no publisher, no backing, “no family helping me—I don’t have a boyfriend or anything,” Rohrback decided she would publish her book herself. The cover features two different pictures of her floating alongside a fiery white steed.

“This book finally let me experience my inner horse. I was like a child again, prancing through the woods. At one point, I was convinced I had four legs. A smile radiated from my face. I punched the sky, knowing that I was free. Call me Prancer, for I walk my path with joy.” [The Daily Beast]
