One of the most useful features of owning a smartwatch, right up there with being able to get notifications that vibrate on your wrist instead of your phone making a noise, is their ability to monitor your heart rate. Whether it's tracking calorie burn or monitoring stress levels, heart rate trackers play a crucial role.
Being able to keep a digital eye on the speed that your heart is pumping at provides a great deal of insight into your fitness, it will help you exercise more effectively, and being able to see and track your improvements will provide a greater boost to your chances of carrying on with your exercise plan rather than giving up and ordering a takeaway.
