Hello,
I took loads of exercise, walking mostly but quite often lifting weights with my right arm in the pub too,
, during my chemo. That was back in Dec 2008 - March 2009 and not exactly the ideal weather, but I really felt that it was doing me good. As my cancer symptoms receded, courtesy of the chemo, I found that I could do more and more exercise. It was a real bonus as I live in a beautiful part of England, the South Downs and walking through the stunning scenery just added to the whole experience.
My chemo turned out to be a real breeze, although I'm not entirely sure the exercise was the reason, but it sure felt good.
Cheers, Mike
