in my work place i’m probably the only one who exercises. comparing myself with them, i find the only difference is that they’re just not predisposed to being active. it’s all in the mind. instead of taking the elevator, i just run up the fifth floor. after a while, it’s nothing. i go to a nearby convenience store to get a snack, i climb down. then going back up, i climb up. i hardly take the elevator.
as for chairs, i got to pick my own. and what i picked was a simple one: no arm rests, with swivels, light, and swift on wheels ;). it’s almost like a stool… my idea was this: the less time i spend in front of the computer the better. the easier i can stand up from my chair the better. some of those “ergonomic” chairs are really comfortable. and therein lies the problem. they’re too comfortable to begin with, it encourages you to sit all day. i prefer to spend 30-60 minutes at a time in front of the computer. it’s not absolutely necessary to spend more than that anyway, even at crunch time. i get up, do PK rolls, climb up or down the stairs, vault over the stair rails, do push ups, anything. personally, i cant stand sitting in the front of the computer all day. but that’s because i’m inherently active. i dont have to convince myself to get up. i just do, or else i feel rotten or get a headache.
another tip: might be useful: set your mouse cursor to no acceleration and lower sensitivity. this will teach you to use your arms, not your wrists. i find that accelerated mouse cursors tense up my muscles in an effort to control them. but that’s just me. i also think there’s a certain discipline you can employ by lessening unncessary mouse movement. for example, when i work in maya, i used to navigate like a bee: pan-zoom-rotate-zoom-rotate-pan-etc-etc like i needed to fine-tune everything (if you guys ever watched gnomon videos, you’d see mr alvarez navigate like this). this caused pain in my wrists: too much movement.
