Correctly interpreting data from your fitness tracker is important in order to derive the most benefit from the device. These 5 simple tips will prove most advantageous while using your fitness tracker.1.\tPay attention to your total time and distanceIf the data displayed by the fitness tracker seems too complicated you may start by simply looking at the total time spent running and total distance covered. A simple rule is what is called the coaching standard which says that gradually build up your endurance by increasing the number of kilometres run or time spent running. For example if in your first week you run two kilometres then in the following week try running three kilometres. Or, if you run for ten minutes during the first week try adding five to ten minutes in the subsequent week.2.\tCheck your pacePace is measured in minutes covered per kilometre. It offers an estimation of effort made during the run.People often start running at a slower pace in order to conserve energy and to be able to run for a longer duration. Your fitness tracker helps you keep a track of your pace.3.\tChanges in elevationIf your fitness tracker measures changes in elevation then that is an important measure to consider. Speed varies depending on whether you are going uphill or down.4.\tCadenceCadence or steps per minute is directly related to running economy or running efficiency - the amount of work you have to do to maintain a certain speed. The most efficient cadence is about 180 steps per minute.5.\tHeart rateIf a variety of data confuses you, just consider heart rate measurement. Track your heart rate data both during and after your workout. This will help you understand the exertion level you're having. According to experts, lower heart rate helps to build endurance. In order to improve performance, it is important to spend within 85 per cent of your maximum heart rate during your workout. The formula to determine your maximum heart rate is 220 minus your age..Apple Watch UltraFeatures: Compass, always-on altimeter, Water resistant (100 meters), 3 certified IP6X dust resistant, blood oxygen sensor, (blood oxygen app) electrical heart sensor (ECG app) third-generation optical heart sensor, high-g accelerometer (up to 256 g-forces with fall detection and crash detection), high dynamic range gyroscope and ambient light sensor, international emergency calling, emergency SOS, International roaming..
