I had minor surgery two weeks ago (septorhinoplasty and turbinate reduction). I was cleared to do light exercise, but can't get my heart rate or blood pressure up too high yet. I want to start using the trainer, but is it any benefit to just do some easy spinning to get the legs moving but keep the heart rate down? (Max HR is 184, so I'm thinking about keeping it below 140bpm)

I know I'm not going to gain fitness right now, but I don't want to lose any. It's just driving me crazy not to do anything, and my legs are achy from not moving much. Plus, I figure just being in the cycling position will help my core and arms stay used to riding.
