Check your heart rate on Apple Watch

Receive low cardio fitness notifications
Apple Watch can provide you with cardio fitness estimates by measuring how hard your heart is working during an outdoor walk, run, or hike, and send you a notification when it’s low. Depending on your age and sex, your cardio fitness will fall into one of four ranges: Low, Below Average, Above Average, or High. If your cardio fitness level falls in the “Low” range, you’ll receive a notification on your Apple Watch. If it stays low, you’ll receive a notification every four months.
Note: This feature may not be available in all regions.
In the Health app on your iPhone, tap Browse, tap Respiratory, then tap Cardio Fitness.
Follow the onscreen prompts to turn on Cardio Fitness notifications.
You can also look in the Cardio Fitness section of the Health app to see your cardio fitness measurements and the range they fall into. Tap Show All Cardio Fitness Levels.
Note: For best results, the back of your Apple Watch needs skin contact for features like wrist detection, haptic notifications, blood oxygen level measurements (Apple Watch Series 6 and Apple Watch Series 7 only), and the heart rate sensor. Wearing your Apple Watch with the right fit—not too tight, not too loose, and with room for your skin to breathe—keeps you comfortable and lets the sensors do their job.
