So far, I've tried the fitness ball. It was too much fun. It also is bit too small, so have to try a different size.
I've got a small pedaler under my desk for any time I start feeling drowsy. I do about 50-100 revolutions as fast as I can and it really gets my heart rate up. Hard to feel drowsy when you're panting.
I also have a hand squeezing device to exercise my hands when I'm not typing.
To work on my core when I'm sitting in a regular chair, I took the armrests off my chair and lean as far over to one side as I can (sometimes touching the floor), then the other. It not only exercises my waist, it pops my back and feels good.
I also used to do chair exercises. Alternate between raising heel then toes back and forth for a half hour. Bun flexes: clench one cheek then the other. (make sure no one is behind you because this looks funny to someone who doesn't know what you are doing).
