Joanna Rohrback uploaded the video you see above to YouTube back in December, but it received the social web's full viral attention this week. The clip, introducing a form of exercise called "Prancercise," shot up from just over 10,000 views at the beginning of the week to more than 2.7 million as of Friday evening.

There's just one problem, however: much of the attention has been negative, full of snark and mocking Rohrback's unique workout regimen.

Rohrback describes Prancercise as "a springy, rhythmic way of moving forward, similar to a horse's gait and is ideally induced by elation." She's also got a Facebook Page set up now and available book on Amazon.

But despite the derisive attention this week has brought Prancercise, Rohrback says she isn't phased.

"Let them laugh," she told CNBC on Thursday. "Who would pay any attention to a boring, average, everyday video? I am so glad ... I have my confidence."
