You have to use critical thinking + it helps to have some info on the subject + it shouldn't be used to perform self-surgery :)

I spent about 12 hours over 2 days, checking, rechecking, and building out a plan. Then I did 2-hour sessions on YouTube, over several weeks, learning the new exercises with proper form (and that continues as form is hard). Followed by an appointment with a trainer to test my form and review the workout as a hole (which he approved of). No trainer really knows how this injury will manifest, so a lot is also helped because I have 10 years of exp.

This isn't a button click, and now follow the LLM lemming. This is a tool like Google search but better.

I could not have done this before using the web. I would have had to read books and research papers, then try to understand which exercises didn't target x muscle groups heavily, etc. I just couldn't do that. The best case would have been a trainer with the same injury, maybe.
