What does it mean when my iPad app tells me I've burned zero calories?
The stats at the end of the workout (Challenge results and Calories) are not in realtime. You need to update the page or refresh it in order to see the results. If you're using the app, you would need to go back a page, then click that workout again. Since you just completed it, it wouldn't start the workout over again, but rather show you the updated results page.
