A couple of things to add to what Ellie said - walk, walk, walk. Can't stress that enough. Get up every 30 minutes or so and walk around the house. Go stand at the kitchen counter and go up on your toes, then back down. Repeat 30 times. You can sit in a straight chair and "march" with your legs. There are lots of small exercises you can do on your own with no special equipment.
There were times at the beginning that I wondered when I would be able to put on my shoes and socks - by myself. Time passes faster than you think it will.
Lots of :love: :love: :love:
