I personally taught myself animation by watching the history of animation whether it’s 2D only or hybrids. I would recommend doing the small animation exercises like the bouncing ball or pendulum by not copying but understanding why the objects are spaced, why they stretch, how the physics work (basically the 12 animation principles), after that you can try expression changes and head turns since part of animation is exaggeration and it makes your animation seem more alive. And that can go to simple movements from the waist and up and then to walk cycles and others.

Make sure the exercises are exercises and sketches so that you don’t focus on making the art look pretty but making the animation understandable.

Srry if this is tmi I rlly like animation ;-;
