I'd imagine it's things like training a dominant hand. The skills required for precise motor control, to produce the right movements for e.g. handwriting. Since the wiring is so long, and feedback is delayed, you need to be able to precalculate these movements.
Also imagine how e.g. an intent to move somewhere actually gets implemented. You don't always have to think about each individual step of walking, or pay explicit attention to things like your sense of balance. You probably don't even have to choose that you're going to walk, or think about how to get up. When you want to go somewhere, you just do it, and somehow it's all calculated for you and happens.
When you try to move a specific limb, how do you know which muscles correspond to that limb? In fact, how many of those muscles can you even individually address? You can learn to individually address them, but I bet you don't come with that ability by default.
Then of course there's the question of what even causes your limbs to move once you will them to move.
