Undulation of the Week: Coffee Grinder

This advanced undulation, #45 from the book, is a variation of a belly dance move. Back and abdominal muscles get stronger and more flexible as the movement of the torso separates from the hips.

Even though the photo demonstrates this undulation in a standing position, it's also effective seated--even for people in wheelchairs. It requires strength of core back muscles, so I advise developing that strength with the beginning and intermediate exercises before trying the Coffee Grinder.
