Effects of exercise vary depending upon the extent to which the heart rate is being pushed.  If the intention of working out is to burn fat, then the heart rate is kept at a lower level throughout a typically long workout session. On the other hand, if the underlying intent is to build stamina, the heart rate is pushed up for a short duration. Therefore, to be able to maximise the efficiency of your workout, it is critical to keep an eye on your heart rate as well.

Heart Rate Monitors (HRMs) can be extremely beneficial in tracking your heart rate at any given point in time. Such devices are all the more important for professional sports people and serious fitness buffs since they come decked with all the latest features and offer a very high degree of precision. Usually, such high-end monitors cost over 300 dollars.

 Why Buy A Heart Rate Monitor?

Heart Rate Monitors are not just gadgets that help doctors conduct a preliminary cardiovascular health check. They have slowly become an important fitness tool used to check the effectiveness of regular workouts. They tell you if your workouts are too harsh on your heart or if they need to be intensified further to help you reach your fitness goal. A heart rate monitor can be used even when you are not exercising to help you measure your heart rate at different times.

For instance, you can find out how your heart is functioning while exercising, while you are engrossed in your daily chores, and also while you are resting. These figures prove vital when you are trying to gauge the extent to which your heart is getting strained and whether you are on the right track towards achieving your health goals.

 Buyer’s Guide for Buying A Heart Rate Monitor above $300


Usually, heart rate monitors come in two variants – those in the form of a wrist band and those in the form of a chest strap. The wrist bands are preferable as they are comfortable to wear and convenient to read. They come with easy to read displays that can be looked at even while in the middle of an intense workout like running on a treadmill.

Chest straps are not very convenient because they often come loose and slide down, causing errant readings. Also, it is very difficult to adjust such a device in the midst of a workout. Besides, with such a device it is next to impossible to check the heart rate while working out. Chest straps are usually connected to trackers that display the heart beats on an external monitor.


When it comes to accuracy, chest straps have an upper hand as compared to wrist bands. In fact, Polar H10 Heart Rate Monitor (Bluetooth HRM chest strap) is touted as one of the Most Accurate Heart Rate Monitor above $300 available in the market. Investing in a heart rate monitor that isn’t precise is the last thing that a professional sports person would like to do. It is, therefore, advisable to read chest strap heart rate monitor reviews before choosing the correct one.

 Smartphone Compatibility

Nowadays, most heart rate monitors are smartphone compatible and can be synced with your phone to get comprehensive workout information and analytics at the tip of your fingers. Both the chest-strap HRMs and the wrist-based HRMs have smartphone compatible versions. One of the best heart rate monitors above 300$ with smartphone compatibility is Suunto Ambit3 Peak Hr Running Gps Unit.

You can find smartphone compatible HRMs at a much lower budget range also, however, the ones that cost above $300 usually boast of extra features like displaying phone calls and notifications, in addition, to accurately reading your heart rate and other fitness parameters. Some of these devices can be attached to bikes and can act like ANT+ devices which send out cadence and speed data to your smartphone. However, it’s important to keep in mind that some smartphone apps can track the heart rates only through the chest-straps.

Display and Ease of Use

One of the important aspects to keep in mind while selecting your heart rate monitor is the their clarity of display and readability. The data should be presented in a simple and easy-to-read fashion. Also, the display should be clear and its font size should be large.  Monitors with a backlight are convenient for those who may go for a run in the dark like early in the morning or late at night. Some of the HRMs above $300 are built to give audio updates while connected to the smartphones so that you don’t have to check your phone or the device display while working out.

Heart Rate Variability and ECG

Some heart rate monitors above $300 now measure HRV (heart rate variability). HRV is a measure of the millisecond deviations from a regular heartbeat and is quickly replacing resting heart rate as the gold standard for determining how rested or fatigued you are. If you are training for a rigorous event or even when you are juggling many physically taxing tasks apart from your regular workouts, look for a heart rate monitor that measures heart rate variability.

Devices that can perform an ECG, like the Withings Move ECG, can help detect early signs of heart conditions like AFib (Atrial Fibrillation), but they present a double-edged sword. You can be lulled into a false sense of security if nothing appears to be out of order. Dr. Neal Stansbury, MD, an orthopedic specialist at VSAS Orthopaedics in Allentown, PA (also a former professional cyclist who battled a heart rhythm disorder), says these home readings “can be helpful in that it alerts a person that a problem may be present, as long as the person doesn’t try to self-diagnose.

While having access to this technology 24/7 may make you feel like you have all the information you need, Dr Stansbury cautions “if you feel as though something is wrong, regardless of the monitor, seek help from a doctor.”
