I need to lose weight but I have a lot of problems with my back and deal with lower back pain daily…plus I have sciatica in one leg and too much movement/exertion causes it to flare up.

Are there any exercises (besides swimming) I can do thats low impact and wont cause me too much more pain?

First try to take care of your Sciatica. Here’s a article I wrote.
