Exercises to do with a leg injury?

caitlinlws

Yesterday I injured my achilles tendon...very painful to walk and move around, and most likely going to be out of comission for a week or so...any suggestions as to what I can do to burn calories while staying off of it?
I do have a pilates dvd that I do frequently, but I was looking for something to supplement that with since it isn't very good for cardio....
