I love to exercise but with a broken spine it's difficult at best. I have improved enough to walk most days so I challenge myself to walk just a little further and a little further each day. It helps too that I can walk right out of town and see the fields, pastures. horses and cattle as I walk. I'd give anything to be able to get down on the floor and do situps, pushups again or even an aerobic class would be fun! Do it while you still can!!!!!
