Which is better: a wrist or chest strap heart rate monitor?

Which is better: an armband or chest strap heart rate monitor?

By the Vetturino team | www.vetturino.nl

Whether you're training for a HYROX, a new FTP test on Zwift, or just running your usual route with Strava: insight into your heart rate is invaluable. But then the question arises: do you choose a chest strap or an armband heart rate monitor?

In this blog, we explain the difference between both types, so you can make the right choice.


šŸ–¤ Chest strap heart rate monitors (ECG) – Maximum accuracy

A chest strap like the Coospo H808S uses an electrocardiogram (ECG) sensor. This directly registers the electrical signal of your heart rate, making it extremely accurate, even during peak exertion or interval training.

  • Highly accurate (comparable to medical measurement)
  • Long battery life (up to 300 hours)
  • Reliable for intensive sports such as cycling or HIIT

Disadvantages: slightly less comfortable, needs to be tight for accurate measurement.

šŸ– Armband heart rate monitors (optical) – Comfort and convenience

The Coospo HW9 measures your heart rate using optical sensors (LED light). You wear it on your upper or lower arm, which is more comfortable than a chest strap – especially during longer sessions or strength training.

  • Comfortable and quick to put on
  • No wetting or adjusting needed
  • Rechargeable and compact

Disadvantages: slightly less accurate with rapid heart rate changes.
