I use the Android mobile app primarily . I don’t always pay close attention to the instructional text but sometimes I wish I could go back and read it again or my brain wanders and I miss it.
My suggestion on the mobile app is to have the lowest “section” of the app, where the instruction text appears, have another swipe left/right panel that shows the most recent instructional text. If you allow up/down scrolling and I could go back thru previous instructions too.
This new instruction panel would be in addition to the workout image and the set / interval text panels.
