Pregnancy Workouts

Options
I'm on a few restrictions because of issues in my medical history so I was wondering if anyone had any suggestions outside of walking (b/c I do plenty of that already) and lifting dumbbells. My restrictions are as follows:
- Don't lift anything above 10 pounds
- No ladders/step stools
- No excessive bending or over-reaching

I want to be able to keep some form of light exercise going, especially for my thighs, b/c I already feel like a fat blob.
