Disabling or Exercise?

After going up and down the stairs a billion times to do all the built up laundry that had accumulated when my washer and dryer both decided to bite the big one at the same time a few weeks ago, I'm happy to have my new machines (which are much better) but I think I'm going to need disability insurance because my back is about to go out--for good. Wow those stairs are murder and I'm even in better shape than I used to be with all the working out I've been doing. Not enough obviously. Well, if it doesn't kill me, I guess it will make me stronger and I keep telling myself at least I don't need to spend my money on a stair master.
