I was actually informed that not resting the hands is a better idea, and that makes a lot of sense, because you aren't placing your weight on your wrists. I never get any pain in my wrists from floating, which I used to get while resting, and I can also move my fingers much more easily.
There's no reason that resting your wrist should be good, because then you're applying more strain on your hand than just the keypresses.
Hmm, strange. I've never had RSI issues or anything of the sort, but just trying it out now, there's far more tension in my wrist when they're not resting. Actually typing like that is far more strenuous than just using my fingers to type while my wrists are on my tray.
(edit) - Could also be because of my arm rests from my chair are taking a good chunk of the weight off my wrists. Working without an arm rest would be a nightmare methinks.
I have something akin to RSI; whenever I type at my normal pace (over 120) for long periods, my fingers themselves feel swollen and heavy. These days' I've been practicing a little less because of that. When typing for comfort, I like to use the rests on my chairs for my elbows, but it does slow me down by anchoring me. My right arm moves a decent bid to the bottom row on Dvorak, and therefore I keep my right thumb off the spacebar to free it up. My left hand can be doing pretty much whatever, as it pretty much doesn't move.
Perhaps it's because I try to put my weight on my arms when I type, by always keeping my arms up. I keep my board at a good height, though, so it's never tiring.
I agree that when I'm not going at my maximum speed, resting is preferable. Still not sure if it's better for the wrist or not, though. Never had any problems myself either way.
