Knitting while exercising and vice versa

Ellen over at L.A. Is My Beat got me thinking the other day. She blogged about walking for exercise and not quite figuring out to knit and walk at the same time. Walking and knitting would be quite difficult for me because I usually walk with Large Dog pulling me along. However, I realized that I could probably knit while sitting on the recumbent stationary bike at the gym. I tried it out, and it's great! I do knit a little slower, and I can only do basic stockinette or ribbing, and the yarn can't be too splitty, but that's fine by me.
I would have loved to take a photo, but I think the gym frowns upon such things as cameras in the gym. Instead, I can show you what I worked on. It's the gathered pullover from Interweave Knits Winter 2007. The yarn is Blue Heron cotton/rayon/metallic. You can't see the bits of metalllic in the photo, but it adds that little bit of glitz.
