This might sound stupid, but every time I've recorded (or played live), I am thankful I've done it.
Since there is a lot of sitting on your arse doing nothing, before you start recording, take
yourself to the bathroom, and run your dry hands under the hand dryer for a couple of minutes, warm
everything up, that way the muscles in your hands will be nice and relaxed...
like I say, sounds silly, but you'll avoid any cramps, or tight muscles that might slow you down.... Try it!!!!
