Need some ideas for cardio without using legs

summertime_girl

Having knee surgery in a few weeks, and anticipating 3 weeks of being unable to walk without crutches, and 6 weeks (or more) of not being able to exercise using my legs. Looking for something to burn calories, that won't use my legs.

I recommended this video workout to my mom when she had foot surgery: http://www.youtube.com/watch?v=LtrciwU4Fbo

It's upper body cardio while sitting in bed.
