# totalEnergyBurned

The total active energy burned during the workout.

```
var totalEnergyBurned: HKQuantity? { get }
```

## Discussion

This property contains a quantity using energy units, or `nil`.

> Note:
> Provide a total energy burned value whenever the active calories burned is relevant to the workout type. In addition, add active energy burned samples to a workout using the ``doc://com.apple.healthkit/documentation/HealthKit/HKHealthStore/add(_:to:completion:)`` method. These samples should sum up to the total energy, while providing detailed information about how the intensity changes over the duration of the workout.
