What muscles are you supposed to use for Stepmania?

[Outer Force]

One thing that keeps bugging me is wondering which muscles you should use when playing Stepmania. Should you plant you wrists firming on a table and not let them move? Should you use more of your fingers, your wrists, or forearms? Any help appreciated.

I usually plant my wrist when playing easy songs, but for long fast streams, i pick my wrist up, it lets me move my fingers around quicker. I always have my elbows planted on my arm rest too
but thats just me, i also just play with my two index fingers on my key pad (2,4,6,8), and throw in a couple others when you have hands.
so i dont use my wrist, because i lock my arm up for fast streams, that would leave my forearms and fingers, and biceps i guess because im flexing my arm to keep it locked.

its all in the way you play, everyone plays differently, other set ups work better for other people.
