1. Fitness Tracker Basics
Fitness trackers are usually wearable devices that have the ability to track fitness-related points, such as your heartbeat during both activity and rest, your footsteps, and the amount of calories, and the distance you have run or walked. Many of them also have the ability to track the calories you have consumed and burned based on your weight, height, and other factors that are helpful for a balanced lifestyle. Many fitness trackers can be paired up with apps and services in order to more elaborately keep track of your fitness progress. Some can link up with exercise machines, such as a treadmill, to better track your heart rate, calories burned, and distance run.
