Body movement monitors are beneficial to those who want to work out and maintain fitness. One of these helpful gadgets is heart rate monitors. Heart rate monitors are special gadgets that tell you how fast your heart rate is and how hard does your heart muscles work while you exercise.

Monitoring your heart rate during exercise is beneficial because it tells you when you need to rest, slowdown or work hard more to achieve a heart rate that suits your fitness needs. There are various heart rate monitors available for you to use such as chest strap monitors, strapless monitors, watch monitors and others.

The way heart rate monitors track the heart actually depends on the type of heart monitor you will use. But generally speaking, heart rate monitors use a device that sends signals from the chest to the monitor itself. Strapped heart monitors directly send signals from the chest straps to the monitor while strapless monitors use indirect transmission of heart rate readings. According to experts in heart monitors, strapped monitors are more accurate because of the direct transmission of data.

How Signals are transmitted

Heart rate monitors use two parts in order for the electrical signalling to reach the monitor itself. These consist of a transmitter and a receiver. A transmitter is usually wrapped around the chest or attached to a belt. A receiver on the other hand, is worn on the wrist like a watch or other gadgets.

During any activity or exercise, electrical signals are transmitted from the heart muscles in order for the heart to contract. Transmitters usually detect these electrical signals in the heart through the skin. When the transmitter picks up the signal, it sends analog or digital data to the monitor in the form of a heart rate; thereby your heart rate is being displayed on the receiver.


Strapless monitors for that matter use an ECG or electrocardiogram data that is being detected through the pulse on the wrist. Strapless monitors tend to be less accurate because they are located far from the chest unlike chest or belt straps. Some

Benefits of Heart Monitors

Conventional monitoring of the heart rate during exercise involves another person checking your heart rate or pulse rate simultaneously while you are doing your exercise. However, since you need to monitor your exercise response most of the time, having another person checking your heart rate is not very conventional. Due to this, heart rate monitors allow you to exercise while monitoring your heart rate on your own.

Heart rate monitors may help you check if you have been doing your workout effectively or not. Heart rate monitors also help you determine when you need to critically rest because your heart rate has been reaching very high. Some heart rate monitors signal you through beeps if you have reached your desired heart rate or you have been reaching very fast heart rates. In this line, heart rate monitors should be one of the gadgets you need to bring during your workouts.
