I am currently wondering, in a very similar vein, if the people who work on Apple Fitness have ever trained for an event in their lives.

The optimistic view is they've left plenty of space for third party apps to come in and thrive, and a number of them have. But if you were trying to build an app that bridged people from sedentary lifestyle to an active one that needed a 'Real Fitness App', well they haven't really done that either, and I can't help but wonder if it's a personnel problem.

The workflows are all wrong for adjusting things the night before a session and much worse for correcting things in the middle of a workout.
