In the past, I have been unable to lose any weight without exercise and I just sprained my ankle on a family vacation about 2 days ago. It is so frustrating to just sit there with my leg elevated and icing! All I want to do is go the gym and lose weight.

Ugh, sorry frustrated ranting. I think I'm getting cabin fever from not doing anything at all but sit on my butt...

Well don't go off your eating plan like I did when I hurt my foot last year. That resulted in a huge gain for me and having to begin the battle all over again. Maybe you can at least sit and do some light dumbbells for your arms to make yourself feel like your doing something physical?

If you have exercise videos, or can watch one on TV, you might be able to do some of it with your arms and hands. Kicks become punches or lifts. Do them low to strengthen and high to bring your heart rate up.

When I first started learning to modify "normal" aerobics for my too-heavy body, one of the first things I learned was that if the movement is too much for you, drop the arms and concentrate on the feet. Add the arms again when you need to raise your heart rate.

The same works when you can't use your feet at all. Any arm motion above your chest will raise your heart rate and help you burn fat. That's what "chair dancing" and other seated exercise is all about. There is a whole community out there that can't use their legs at all, or who need to sit while exercising, and there are exercises for them, too. If you Google "seated exercise" you may find some options that will work for you.
