To find exercises that you can do now, go to bodybuiler.com and livestrong.com. I use these sites to get exercises I can do because I have a bad back. They accommodate everyone's physical abilities/disabilities. And it's free. There are thousands to be found on these sites.
So until you get your membership, give them a look.

May I be free to be the me that I came into this world to be.
