Surprisingly, the best thing I ever did for my RSI was doing pushups on my fists instead of my palms.
Another thing that seems to help a lot is keeping a natural arm pose on the keyboard despite not having a natural keyboard. My only problems these days are with the thumbs, for some reason they don't like the way they're resting on the keyboard.
