is it possible to study a step map without actually playing?

my favorite rhythm game is Pump It Up but I'm not able to make it to my local arcade often. Which is to say that I can only get so much active practice in + I feel like I have to de-rust every time I play again.

Maybe I'm mistaken but I feel like I've heard of people studying step maps even if they aren't at a machine. how exactly could I put this into practice or possibly find a way to keep maps fresh in my mind between arcade trips.

thanks!
