Hmmm. . . I was always under the impression that aerobic exercise burned fat
equally off all parts of the body, and that, likewise, weight bearing
exercise strengthened all the bones in the body. If this is not true, then
would we not have to do weight bearing exercise on each and every bone in the
body, to prevent bone loss in every bone?

Another question- I have quite a lot of nerve and other damage to my back,
both in the lumbar and cervical regions, which prevents me from doing much in
the way of weight training of any sort. Fortunately, I can, and do, walk. I
am working on slowing increasing the incline on my treadmill more and more
each week. It feels to me like walking slower at a steeper incline becomes
more weight bearing and less aerobic, as the incline increases. I am
wondering if this is true, and also, if adding ankle weights as I get in
better shape would also increase the weight bearing effect of this exercise.
