You make a great point. What if Apple did the equivalent of iBooks Author but instead of creating eBooks or iTunes University for creating online courseware it let individual instructors design workouts they could then sell? Then again Apple still doesn't let third parties design their own Apple Watch faces. Seems like it would still be a pretty good and logical extension of iTunes U.
