Upper Body Chair Workouts (after knee surgery)?

[sheepla]

I'm having my second knee replacement surgery at the end of the month (this is good news). I've been down this path before so I know what the recovery is like but this time I'd like to focus on my upper body, doing chair workouts, while early in the recovery process. I've been neglecting upper body work lately Does anyone have any suggestions of upper body workouts that can be done entirely sitting in a chair? DVD or Youtube is fine.

Tamilee's IWTB Arms (segment two I think) is the only one I can think of off the top of my head. Even it would have to be adapted as I think it has tricep dips which I wouldn't be able to do.

I'm trying to remember if any of my stability ball workout segments just involve sitting on the stability ball (where I could use a chair instead) or if all involve some reclining.
