How Do Heart Rate Monitors Work?
We often take the modern marvels of technology for granted. In many cases we don’t care how something works just that it does. When talking about heart rate monitors, however, the how of their functioning is pretty interesting. These little tools can have a big impact on the quality of your workout so learning just how do heart rate monitors work can be useful in reaching your fitness goals.
There are two basic kinds of heart rate monitors, those with a chest strap and those without. While there are numerous monitors on the market, we will talk about the Reebok monitors we carry here for purposes of this review.
The Reebok Heart Rate Monitor with Chest Strap features a wrist band and a chest strap. If you are wondering how do heart rate monitors work and are specifically concerned about the variety with a chest strap, this one is for you. Chest strap heart rate monitors work similarly to EKG’s in the hospital. Small electrodes located in the chest strap sense electric signals that your heart creates with each beat. This information is relayed to the wrist band via a radio signal and displayed on the screen.
Strapless heart rate monitors work slightly differently. Because they are not able to sense the signals from the heart, these monitors require you to place your fingers on them. The Reebok Heart Rate Monitor has two sensors where you place two fingers. The computer within senses your pulse through your fingertips and provides information this way.
“How do heart rate monitors work?” is a completely rational question. When you are looking to invest money in fitness equipment, it is important to understand what you are paying for. Using a heart rate monitor to ensure you get the most out of each workout is a great way to maximize your results.

Most of us know how to take our own pulse. Depending on your age, you likely learned it in elementary gym class, where everyone would stop, place their fingers on their neck (carotid artery) and quietly count as the teacher timed you. While this is a great method for checking your pulse, it isn’t the most convenient in the middle of a workout. One of the main benefits of exercise with heart rate monitors is being able to track your heart rate mid-workout without stopping.
