Alyssa - even if you pause the diet, please continue to exercise. It will help your energy levels and frankly I think that exercise is part of a healthy lifestyle and should not strictly be associated with a weight loss plan (though of course it does help that, too).

I agree with this even if you have to exercise strictly indoors. You can use household items as weights or a sofa/chair for step-up exercises. Moreover, you can find some exercise videos. I'm sure there are some for your back.
