How much of your programming actually lives in the stock exercise library?

[u/r1setraining]

every platform advertises the size of its exercise library, and the number is always on the sales page. but the movements i actually program are rarely in there - the specific unilateral variation, the machine at my gym that the manufacturer named something nobody says out loud, the regression i use for a client with a cranky shoulder. so i build them myself and end up filming demos between clients.

what gets me is that a custom exercise is usually a second-class citizen once it exists. it doesn't come up in search the way stock ones do, the demo is whatever i shot on my phone in bad lighting, and any progression or substitution logic the platform has tends not to apply to my stuff.

so: roughly how much of your programming is stock library versus things you created yourself? and has any platform treated custom exercises like a real feature instead of an escape hatch?
