At Home Low Impact Exercises HELP!

MrsWendyQ

We've recently moved and the roads near our house aren't good for walking. There are a lot of hills, turns and crazy drivers! I want to pick up where I left off and lose the last 30 some pounds I have to go. The only problem is I've got a very bad back and I'm not allowed to do anything jumping or jarring, and no running! (Doctor says hill are the worst for my scoliosis as well) Also, I've got some issues with my knee so I try to limit things like squats and lunges as they really cause problems. I'm looking for at home workouts to try. Anyone have anything to offer?
