There are apps where you can see how others train. And not on paper in theory, but their actual workout they did in the gym. It is increadibly cool to see what people do, if you are exploring.

To piggyback onto the above comment:

You can watch actual workouts in real time and usually they have a chat command such as !currentsession that you can type in chat and it will provide a set-by-set breakdown of their current gym sessions. You can also ask questions during their stream which they will answer during their rests between sets.
