Gaiam’s Calorie Coach from Oregon Scientific
4. Gaiam’s Calorie Coach from Oregon Scientific ($39; available at Best Buy stores and us.oregonscientific.com)
Why we like it: Not only is this handy pedometer one of the most accurate monitors on the market for counting how many steps you take each day—and calories you’ve burned—but we love its discreetness. Unlike most pedometers that have to be clipped to your waist in order to work properly, the Calorie Coach can be placed anywhere on your body, such as hidden inside a shirt pocket, placed in your handbag, or, even hung from your neck.
