Scifi movies about a prisoner who gets stronger abd more durable the more he is tortured. Can't remember if it had something to do with nanobots or some kind of blood pathogen

Vaguely remember he is in a prison setting in a circular building and the guards are responsible to torture him daily. Broken bones heal faster and become stronger etc.

Is it possible that it is not a movie but an episode of a series?
This is really just a very wild guess, maybe?:
Episode “Cold Station 12” of the TV series “Star Trek: Enterprise”
