Aerobics when you can't bear weight?

[Guest guest]

I'd like to know what folks have done for aerobic activity when they

are unable to walk. I cannot stand for more than a couple of minutes

without pain, requiring me to sit. I've already lost muscle mass, and

since this is a long term issue, I am concerned that my health will

deteriorate if I don't keep my heart pumping. I will look into water

aerobics, but finances are an issue at the moment - anyone come up wiht

creative ideas, or web site recommendations?
