Bodybuilding Terminology and judging 101

[OldManLogan]

Good morning guys-

Can you recommend any “101” type resources to understanding the following topics for a newbie?
1) Bodybuilding terminology and common phrases, “lingo”.
2) The judging process, what do judges look for etc?
3) IFBB structure/ process (how it works, how people compete, what are the categories, etc etc).

I searched and have been consuming all kinds of content all over YouTube and here, and I’m definitely getting a lot of fragmentary knowledge, but would love an “intro to the sport” perhaps, that’s more concise?

Thanks y’all.
