Chest Strap vs Wrist Heart Rate Monitors

There are two different types of heart rate monitors – chest strap and wrist.

Chest straps go around your chest and take heart rate measurement directly from the chest.

Wrist heart rate monitor go around your wrist like a watch, and most wrist heart rate monitors double for watches and activity trackers. Although these are the most convenient, the measurements are not as accurate as the chest strap and they generally don’t work under water or in pools.

Therefore, we almost always recommend the chest strap monitors to effectively track all 3 sports with a single heart rate monitor.
