Motor skill consolidation

Motor skills are the things we do with our bodies, like running and swimming. To keep getting better, we have to practice the same skills over and over again. Motor skill consolidation is the process of making these skills better and better and being able to remember them, even when we aren't thinking about them. It's like your body and brain storing the skills, so you don't have to keep practicing them all the time.
