Many years ago, I was lucky enough to discover a keyboard training program called Stamina. The author suggested using a more ergonomic hand position: instead of placing your fingers on ASDF and JKL;, you place them on SDFV and NJKL. This way, your hands rest in a position similar to what you would use on an ergonomic keyboard. In addition, the characters on these keys are more frequent, so your base typing speed should increase (especially for cyrillic layout). It was over 20 years ago, and I wonder why nobody uses it and everyone still uses that uncomfortable orthodox hand position.
This is almost exactly what I do. Keep my wrists in line with the forearms, such that they're angled relative to the keyboard. So the home keys aren't ASDF, it's more like QWEF and HUIO. (Although it's more like the home position is in the crevices between those and the keys just below.) I've always done this just naturally and have never had any problems with typing stress or fatigue in 40 years.
