- [Narrator] Muscle memory.

It's how you learn what you do.

Repeat a motor task long enough,

the body will never forget it.

Time comes,

you can do things with your mind

in a world far from the one you're performing in.

Muscle memory is how you can type an email

brush your teeth,

land an airplane,

or dance a masterpiece.

(dramatic music)

- [Instructor] Owen, focus.

Beth, good timing.

(dramatic music)

- [Woman] She's not pacing herself.

- I saw the same fire in you

when you were your sister's age.

- And outta yourself once, I suppose.

- Oh, I'm quite sure I still do.
