Define "total beginner." From your message, it seems that you've exercised before. If so, you probably know enough about form, safety, etc. to be able to do STS (I'm finishing Mesocycle 1 this week).
However, I don't know if this would be the best program to start with after such a long break. It could be a great challenge to start with, or it could be exhausting and overwhelming (too much too soon).
It may be beneficial to start with some less intense workouts for a few weeks to get back into the swing of things, then start STS after that.
However, if you were a total beginner (new to exercise,) I wouldn't recommend STS as the program to start with. There are many workouts and programs that are better suited to absolute beginners.
I don't have an answer for you, but just giving you some things to consider in making your decision.
Good luck!
