No course, learn to copy accurately, consume a lot of art (both art that you like, and art that's objectively good, meaning famous painters).
Then you can choose ONE source to get some basics on figure drawing/anatomy, such as Hampton's book, or Will Weston's course. Draw a lot, do gestures, polish said gestures into figures, and do a lot of master studies. When consuming art, try to think what makes the art appealing, what techniques did the artist use, contrast, saturation, hues, composition, pay attention to how they drew or simplified different elements, or how certain materials were rendered. Take mental notes of these things, or do copies so they stick more in your mind.
Mix this up with some creations of your own. Draw from imagination but always using reference, then reflect on your drawing and what was the shittiest part of it, then focus your next few studies/copies on that weakness. Repeat for 6-12 months and you'll see giga gains.
That's all the "course" you need. Optionally find a friend to do this with, or failing that some art discord so you don't go insane.
