+1 on arm rests. I hate those. They box you in and lift your elbows uncomfortably high thus cutting off nerves in shoulders and arms. The word arm rest implies that these somehow are about resting your "tired" arms. I've never experienced any form of arm fatigue while using a chair. Just not a thing. Complete anti feature. I don't need them. They come off if I have the choice. I won't buy chairs that have them.

Some of my other tricks include walking a lot (during my commute for example) and generally getting up regularly. I have some mini life hacks like getting a glass of water and not using things like water bottles or tea pots that "allow" you to stay at your desk longer. Anything that forces you to get up is a good thing. A simple stroll to the kitchen is a good thing. Standing desks are great too.

Also, because I figured out that a lot of my issues are shoulder related I do some simple exercises to loosen those once in a while. That's also why walking helps. Swimming is also great. If you sit still for extended periods of time, shoulders tend to cramp up and the nerves to your wrists and hands go through there. Where you feel pain and where the problems are are not necessarily the same thing.
