HI KD,
Be sure to try to focus on those abdominals and core too. It will help strengthen the spine overall and take pressure off. I'll look in my water aquatics books to see if there is an exercise.
Google, forward head posture. That is what they call people that get it from their computers.
I think and ergonomic ste-up is important. Maybe its not the lack of arms on the chair but that they were too high. I have an ergo chair with adjustable arms.
Posture is a hard thing. I think I should take a little of my own medecine when it comes to this
