# INStartWorkoutIntentHandling

An interface that handles requests to start a workout.

```
protocol INStartWorkoutIntentHandling : NSObjectProtocol
```

## Overview

Use the methods of the [`INStartWorkoutIntentHandling`](/documentation/Intents/INStartWorkoutIntentHandling) protocol to resolve, confirm, and handle requests to start a workout using your app. Adopt this protocol in an object of your Intents extension capable of validating the workout name or goals.

You don’t actually start a workout from your Intents extension. When your [`handle(intent:completion:)`](/documentation/Intents/INStartWorkoutIntentHandling/handle(intent:completion:)) returns, Siri launches your app and passes it an <doc://com.apple.documentation/documentation/Foundation/NSUserActivity> object that contains the [`INStartWorkoutIntent`](/documentation/Intents/INStartWorkoutIntent) object and your response. Your app uses the information in those objects to start the workout.
