The Hula Hooper with Pace Meter is a little doohickey that you attach to your body and use as an exercise device. I think the object is for you to gyrate your pelvis-Elvis style and literally watch the calories burn away on the calorie counter LCD. $29.95.

It probably takes three days of solid twirling to consume that Snickers bar you had at lunchtime, so don’t buy that new mirror just yet, eh?
