Prancercise

Prancercise is a holistic fitness method based on "a springy, rhythmic way of moving forward, similar to a horse’s gait and ideally induced by elation" created by Joanna Rohrback.

It has been compared to the low-impact aerobics that were popularized by 1980s workout videos.

Many parodies were created in reaction to Joanna’a original video, which themselves have accumulated hundreds of thousands of views.

Joanna Rohrback graduated from Florida Atlantic University with a bachelor's degree in Health Services in 1978. Around 1989 she became a "committed exercise devotee", regularly working out on the Boardwalk in Hollywood Beach, FL. It was on that Boardwalk where Joanna had an experience she claims was the inspiration for Prancercise:

That same year she created the first video to feature the routine entitled “Funky Punky’s Prancercise Program.”

Joanna quit her job and decided to focus on her new discovery. She practiced it every day, “taking years to hone its every gesture and kick.” Rohrback coined Prancercise as a means to vividly illustrate her comprehensive diet and fitness program, modeling it after the “strength and beauty of a horse.” From this she developed four distinct routines: the Prancercise Walk, the Prancercise Trot, the Prancercise Gallop, and the Prancercise Box.

However, 1994 started a near-decade of personal setbacks for Joanna Rohrback. She wrote a book about Prancercise but couldn’t find a publisher. Her mother then began to experience complications from Parkinson's disease – so Joanna became her live-in caregiver. In 2004, after her mother died, Joanna also began to suffer from severe health complications. She was unable to Prancercise for almost nine years.

During this time she maintained a natural healing regimen; by her 60th birthday, Joanna Rohrback was able to Prancercise once again. She decided to focus on her technique and started increasing her daily workouts. On Thanksgiving Day 2012, Rohrback successfully completed a 5k entirely in Prancercise. After this event, she decided to package her idea for the public sphere.
