Okay my problem is kind of weird, more of a problem related to my own personal habits and maybe my DNA setup or wutever hehe

but newayz, here's the prob:
Everytime I wanna play/practice one of my actual piano pieces that require movement like Moonlight and Chopin's Fantasie Impromptu, I have to run warm water thru my hands for a long time and then maybe practice technique for like about 20mins before my fingers can move where I tell them. If I don't do this warm-up process, my fingers are just like cement, they can't move! At first I didn't really worry about this, but then a while ago I was just at this piano performance and I was wondering how those finalists can play those pieces like Listz's Mephisto Waltz so fast and they probably didn't even warm-up in backstage!
So is there like anyway you can train your hands so that they can play at least smoothly not like cement anytime you want them to without warm up? It would be rather embarrassing if my friends asked me to play a piece and then I tell them that I havta warm up a while b4 I can play...
And I also wanna ask, how long do you guys warm up and what do you guys play to warm up during normal practice procedures and also before recitals? And if you have any more tips I would appreciate it very much, thank you!
