Like " If you are having a really bad day, you can do chair exercises. Anything that you can do to increase and keep your heart rate up will do the trick. It doesn't have to be "conventional" exercise. Even using your own weight will help in the beginning. If you can, add weights. At home, cans work great for weight. There are arm bikes. It wouldn't hurt to speak to your doc about things that they may think will help. Good luck. I'm newly diagnosed and I'm still working on eating healthy on a budget. I did make soup in the crockpot that will last a few days. I'm feeding a family of 4. When I get some ideas, I will share. "
