Apple Fitness Plus - Workout details enhancement

I’m an avid user of Apple Fitness Plus - HIIT, strength, Core and Dance especially [since 2020]. For some of the HIIT workouts the description provides the interval details [i.e time spent active and time spent in recovery = 20 seconds on; 10 seconds off or intervals go from 40 seconds to 35 to 30, etc.,], whereas many of the workouts do not provide the details. Details are also not included when watching the preview. Is there a reason why?

These details should be offered consistently for all HIIT; including other applicable workout types. As an added enhancement request, it would also be beneficial for users to see a visual that shows on the screen what part of the body the workout focuses on so that users have the option and can also ensure they are mindful of these focus areas when it comes to maintaining proper form.

Thank you.
