Live heart rate while you lift
Pair any Bluetooth heart rate strap or use your Apple Watch or Wear OS watch, and your heart rate shows during the workout, on the lock screen and on the 3D figure's beating heart.

During the workout
Your heart rate shows on the workout screen with its zone, and on the lock-screen notification or Live Activity during rest. After the workout you get a trace of the whole session, so you can see how hard the conditioning work was and how quickly you came down between sets.
Over time
Resting heart rate and heart rate variability from Health Connect or Apple Health feed your daily readiness (Pro), which decides whether today is a push day, an as-planned day or an easy one. See what heart rate tells you during weight training.
