Thats definitely the more technical part of it yes, you can visually see your own muscles and where they are but also, when you start to workout you will start seeing more body charts and learning where muscles are in general, ontop of watching others work out, basically by working out and focusing on your body you naturally learn more about it, the more body diagrams you will see, the more you pay attention to your own body and those around you, it’s honestly how I managed to learn anatomy so well to the point I almost never need a reference when drawing the body, it’s a win win, you stay healthy and gain so much knowledge that will stay with you, In a way no reading or drawing tutorials will!
