You joke but this is exactly what I'm talking about.
This channel must have hundreds of hours of content, and I'm sure much of it is good, but I don't have hundreds of hours.
Instead, I will send hundreds of dollars to some trusted person to distill hundreds of hours into an app or something that I can use immediately.
No I did not joke. If you bother to open one of the playlists I referred to, you can find e.g. 10 rear delt exercises demonstrated in under 15 second videos with extremely good tldr advice.

Mike Israetel who runs the channel is in the top-5 in scientific body building circles.
And you can get those same videos in their app https://rpstrength.com/pages/hypertrophy-app
Personally I'd use Jefit or Hevy over RP, but the point stands.
