Over the years I've tried just about everything you can imagine. Normal desks and office chairs, a standing desk, pedaling on an exercise bike, walking on a treadmill...
What I've learned through experience is that the best way to avoid any kind of pain, health issues, fatigue etc. is to change things around multiple times a day. Unfortunately, that's a big drain on your productivity when you have to re-adjust your monitors etc. all the time.

The second-best option is lying down. We already do that 8 hours every night, it works.
