Show Workout Samples in Activity App

I have successfully saved HKWorkout samples to the Health Kit database. In the iPhone Health app I can navigate to Health Data > Fitness > Workouts > Show All Data and see all of the workouts I have recorded. In each workout I see Workout Type, Duration, Calories Burned, Distance and Date. However, when I open the iPhone Activity app, and visit the various dates of the workouts, I don't see a Workouts section. I do see sections for Move, Exercise, Stand and Steps which I assume are recorded by iOS or the Apple apps but I don't see a Workouts section with my workouts. Is there something special that has to be done to get workout samples added to the Health Kit database to appear in the iPhone Activity app?
