Sprained ankle

Okay, well someone else is complaining about a broke toe which makes this question seem a little silly, but yesterday I managed to sprain my ankle and I fear that it will take a few days to mend (minor sprain). Does anyone have any cardio suggestions for me until I am up and running again (pun intended)? I imagine I can walk the treadmill until it is healed, but that won't get me the intensity I am accustomed to and there is no rowing machine at my gym.

Do you think I could pull off elliptical or stair limber? It seems like that is also a lot of ankle movement, but I could be wrong.


Thanks.
