Hi thesuperteeman,
Thanks for coming to Apple Support Communities for help today.
You can check your heart rate anytime on an Apple Watch and also set up notifications for your heart rate. This article will tell you how: Monitor your heart rate with Apple Watch
"How to check your heart rate
You can check your heart rate any time using the Heart Rate app. Open the app, then wait for Apple Watch to measure your heart rate. You can also view your resting, walking, breathe, workout, and recovery rates throughout the day. To easily open the app, add the Heart Rate complication to your watch face or add the Heart Rate app to the Dock.
You can also turn on heart rate notifications, so you know if your heart rate remains above or below a chosen beats per minute (BPM), or to occasionally check for an irregular heart rhythm.
Irregular rhythm notifications are available only with watchOS 5.1.2 or later. To enable irregular rhythm notifications, the notifications must be available in your country or region and you must be in the country or region where you purchased your device. Learn where irregular rhythm notifications are available."
For further help with the heart rate feature, please reach out to the health experts here: Apple Support.
Have a fantastic day!
