Research suggests that activity trackers can be effective when paired with two low-tech strategies: setting goals and sticking with them, or working with a wellness coach. When people in a recent study used trackers without specific goals, their physical activity levels actually declined, though many believed they were getting more exercise. Avoid that pitfall by reminding yourself that the real power is in your body — and your mind. Set goals for yourself (10,000 steps, perhaps?) and then use your device to track your progress and hold yourself accountable. Or pair the tracker with outside, human support in the form of a wellness coach. Magic cuffs are a nice idea, but being active and staying healthy through your own power, and effective tools, is even better!
