I recommend setting your arm rests using the following steps:
- Lower one armrest all of the way to the bottom.
- From your normal (hopefully good posture) seated position, hold your arm on that side so that your elbow is at your side and your forearm is parallel to the ground.
- Raise the armrest with your free hand until your adjusting hand comes in contact with your outstretched forearm.
- Repeat on the other side.
It may feel unnatural at first if you have become used to typing with elbows splayed out on arm rests, but if you just stick with the new, lower armrest position for a day or two it will start to feel more natural than your old, high one. You may even notice an immediate improvement in stiff shoulders.
