Chest Strap HR Monitor
The way a Chest Strap HR Monitor works is very simple and smart. The strap has a sensor that uses electrical signals to track your heartbeat. Every time your heart beats, it sends out a small electric signal. The sensor picks up this signal and calculates your heart rate. Most chest strap monitors are connected through Bluetooth or ANT+, which makes it easy to link them to apps like Strava, Garmin Connect, Polar Beat, and others. This means you can check your heart rate live while exercising.
