The human body contains hemoglobin in the blood, and hemoglobin with different oxygen levels also absorbs and reflects light to varying degrees. Utilizing this characteristic, the HS800 optical armband heart rate monitor detects changes in optical volume through a photodiode to ensure the accurate data is obtained.

Why Use a Heart Rate Monitor During Exercise?

Determining your personal heart rate zone and training with heart rate intervals can maximize the effectiveness of your workout. In short, if you train at a lower heart rate (BPM), it will take longer to reap the benefits of exercise. If you exercise for an extended period at too high of a BPM, you will become exhausted before reaching your fitness goals. The HS800 optical armband heart rate monitor provides accurate BPM data so that you can derive maximum benefits from your workouts!

*Heart rate zones vary based on age, please consulting your personal trainer to determine the appropriate heart rate zone for you.
