There are a lot of recommendations for Starting Strength here and I think the book is great for describing how to do a certain kind of lift.

I read it and was still lost about frequency, how to minimize injury, etc. It doesn't give you the practical "do this" sort of advice a true beginner needs or at least this true beginner needed.

I really like Julian Shapiro's guide for the first few months of weight lifting: https://www.julian.com/guide/muscle/intro

I'd recommend the trainer part though - I tweaked my shoulder trying to just figure it out on my own.
