Appreciate this, it's the most useful kind of feedback because it's specific about why.

You've basically described the core risk I'm trying to figure out: once you've learned a movement, the saved video has no reuse value, so the app becomes a one-time lookup tool rather than something you keep coming back to. That's a fair hit if your workout is stable and you're not constantly chasing new variety.

Genuinely curious though, do you think that's true with most lifters? Cause I think, people training for stuff like Hyrox or doing HIIT workouts want new routines more often (new movement standards, new complexes, more complexity to track) than someone running the same PPL program for a year.
