That's a smart take. Even today when I'm learning something new I try to do as much physical typing as possible from the example because I feel like I learn it better.
The other day I had the thought of "all memory is muscle memory" - it's not literally true, but memorizing in an associated form builds up so many cues that it's worth applying to any study: do warm-ups and repetitions, speak, move, and think in sync.
I tend to think of it is holistic memory or whole body memory. The more functions you can involve subsystems in your body the more it hangs together in your brain for longer terms I think.
