Cancer hates oxygen and that is one reason why cancer patients are told by their Drs to exercise. There are many good reasons to exercise: lose weight, tone up the bod, and create endorphines which make us happy people! Before I cracked a bone in my foot back in April I was starting to train to run a half marathon. I am now able to get back to training (at least for the moment). I have been walking around the neighborhood and today I gently hit the treadmill, walked and jogged 1.5 miles s-l-o-w-l-y, my girls told me they don't want to be jostled around too much right now.
