Getting my lizard brain to learn anatomy, need help

Hello there everyone, as the title suggests, I'm hoping people can help me with my want to learn anatomy, either by certain books to buy, youtubers, etc. Now let me explain a little about me and my dilemma. I've been drawing for about 5 years, in that time I've only really practiced learning to draw by jumping straight into things; what I mean is I just looked at pictures I liked and attempted to understand the way the bodies flowed in those pictures, no box method, no Loomis method, etc. At least not originally, those few tips I've picked up over time and applied them, but I'm generally a "wing it" kind of guy. Never been one to sit down and practice the various angles and things on a sketch book I've seen others do, anyways my apologies for the word vomit, let me just cut to the chase. I'm ready to sit my ass down and fucking learn, if I need to take an art class somewhere, fine. Thankfully I live in a college town, that said I'm just slightly overwhelmed and I don't know where to begin, on the other sub "learn to draw" I saw somebody's post a couple days ago talking about going through YouTuber Marc brunet's anatomy learning videos for like two years, and I think I'm going to try my best to do the same, I've never really clicked with Marc brunet and his teachings, so... if not Marc brunet I'm hoping others can perhaps advise me of other avenues of teachings that might better click with me just in case. To put things bluntly, I like to draw women, more muscular women, so if anybody can also guide me to teachings that more specialize in that I'd greatly appreciate it. But, in general, yeah. I'm just shaken up on my apparent weak understanding of the Fundamentals of anatomy. I won't go into what happened so I don't make this post Any longer, but, yeah. If anybody can guide me to resources that might help a lizard brained albeit eager "artist" like myself I'd greatly appreciate it, thank you!
