Keep fit with Fitbit
This California tech company produces the famous Fitbit activity trackers. An activity tracker is a Wi-Fi or Bluetooth enabled device, which you wear on one or, both wrists. Throughout the day, it monitors the number of steps you take, using an on-board accelerometer, as well as your heart rate, and thereby calculates the number of calories you've burned.
Most also tell the time, doubling as a watch. Some fitness activity trackers have an onboard GPS, but most can sync with your smartphone's GPS to track your actual distance walked, jogged or run. Many fitness apps can incorporate this data into a personalised exercise plan. However you choose to track your activity, there is bound to be a Fitbit for you on eBay.
