About products and suppliers:
A heart rate monitor (HRM) is a device users wear to measure and display their heart rate continuously. Electrode sensors in a chest strap detect each heartbeat and transmit the data to a receiver such as a watch, fitness wearable or phone app. The data is displayed as the number of beats per minute.

Heart rate monitors using chest straps with electrode sensors are considered to be as accurate as electrocardiograms (EKG). This sets them apart from the arm- or wrist-based LED heart rate sensors such as the ones found in many activity monitors and smartwatches. They provide real-time input on how hard and how efficiently users are exercising. Heart rate monitor watches are typically used for cardiovascular exercises, such as walking, running, hiking, climbing and skiing.

Bluetooth heart rate monitors can continuously track and record one's heart rate during exercise, as compared to an on-demand pulse monitor which only shows a value at a single point. This frees users from having to stop and take their pulse to determine how intensely they are exercising. Most heart rate monitor models available on have indicators showing whether users are exercising in their chosen heart rate zone. It gives audible or visual alerts when they are above or below that zone. This allows adjusting workouts to stay at the target heart rate by slowing down, speeding up or changing incline or resistance.

Using a heart rate monitor is not the only way users can monitor workout intensity. However, it is one of the easiest and safest ways to take good care of their heart health. Browse through the different varieties of heart rate monitors at affordable prices on
