Nike Fuelband

This might be better than the pedometers most of us have used. But I'm not going to spend $149 just to track my physical activity. I already know I'm not doing enough. I would be willing to bet you would have to wear it on your good arm to have any hope of correct movement activity.

The Nike+ FuelBand is an activity tracker that is worn on the wrist. As part of the Quantified Self movement, the Fuelband allows its wearers to track their physical activity, steps taken daily, and amount of calories burned
