"Exercise mimetics" are fine. You need to look at the professional publications. It's a very active area of research, so things change rapidly.

The newest research: https://jpet.aspetjournals.org/content/388/2/232.long

Here's a nice, but a somewhat obsolete review: https://pmc.ncbi.nlm.nih.gov/articles/PMC8728540/

Sometimes I think that is what metformin and statins do, because weirdly enough both seem to blunt the exercise response. I’d love to take them but I already exercise.

i assume EMS (electrical muscle stimulation)

No, exercise mimetics are drugs that stimulate the same biochemical pathways as regular exercises.
