Bill Pearl’s “Keys to the Inner Universe” or Arnold’s “Encyclopedia”?

Ive looked at both books online, which one would you recommend? I heard that Bill Pearls book is a bit outdated in the nutritional aspect, but has tons of exercises, and he’s one of my favorites. Additionally, since these books are a bit old, are there a lot of exercises in them that people now advise against in hindsight (possible injury)? Thanks. 👋🏻
