Best Resources for Improving Fundamentals of Anatomy?

Hi!

Honestly I’ve been an amateur digital artist for a few years and I’ve been on/off trying to improve my skills.

I always try to learn the fundamentals, but it’s hard to commit to them. I’m not sure if I’m just watching the wrong videos, or if I’m not focusing on the right things.

Is there any playlist/set of videos that actually helped you learn drawing basic shapes/anatomy? How have you been able to actually commit to learning the boring things when your brain just wants to draw the cool-looking characters?
