It's easy to get caught up in the many features available in digital fitness monitors. They may be simple-sensors that track steps or calories. Or they may be more sophisticated, like sensors that capture heart rate, perspiration, skin temperature, and sleep patterns. Some have longer-lasting batteries, light-up screens, and alarms that vibrate or flash as a reminder to be more active or to announce that a goal has been reached. Others have satellite navigation, speed and pace sensors, and even weather gauges. Most link to a computer or smartphone so users can chart their progress.

"We tell people to shoot for 10,000 steps a day, but if they only take 2,000, set the first goal at 3,000," says Dr. Anne Thorndike, a preventive medicine researcher and assistant professor of medicine at Harvard Medical School. Then use the monitor to track progress throughout the day: if low on steps by dinner, take a walk afterward.
