It never ceases to amaze how many new types of workouts are created to help people exercise to tone up and/or lose weight. Add to dancing, walking, stepping, boogieing, jumping and all manner of aerobics the latest way to try to stay fit: the Hula Hoop Workout.

And since he's always on the look out to be on the cutting edge, Dr. Oz on Friday's 'The Dr. Oz Show' (weekdays, syndicated) brought out Christabel Zamor to give a demo of her workout. And to show his audience that he's no slouch, the good doctor picked up a hula hoop and showed everyone how it's done.

Who would have thought, way back in the 1950s, that a once-cool kids toy would become the latest tool in the weight-watcher's arsenal. Doctor-endorsed hula hoops, anyone?
