Is there a way to add time to a workout? I forgot to start my fitness app for functional strength- a new activity.

To manually add a workout (and its data):

1. In the Health App on the iPhone, tap on the Health Data tab at the bottom
2. Then tap Activity and scroll down to Workouts and tap on it
3. In the the top right hand corner of the screen it says add data (or simply +)
4. Tap on that and you can enter a new workout and its data
5. When you are finished tap on add at the top right of the screen.

Be aware though that this only effects your 3 rings on the day in question.

You will have to delete the incorrect workout and enter a new one in the health app.
