Are YOU ready for PRANCERSIZE?

Developed in 1989, Joanna Rohrback shows the world her exercise regimen on how she keeps in such great shape. It's taken from the four gaits a horse makes when it's prancing.

She, unfortunately, is wearing the wrong pair of pants for such a workout.

Would YOU Prancersize??? Or at least wear different pants??? Check out the video below!
