Only do what feels right. Your body is being attacked so much when you take chemo. Really tune in to your body. If it means staying in bed, stay in bed. If it means you feel energised enough to walk, walk. But don't push yourself if you feel sick.
I had cancer 10 years ago when I was 27.
I worked out through my second phase of chemo - I don't remember what it was, but I was OK most of the time with it. My first combo pre-surgery was Adramycin and Taxatere, a really brutal combo that had me hospitalized twice with infections. But the 2nd bout was something with the "C" chemo was not an issue and I was able to run a day camp and start exercising. I worked out every day I had radiation, too: I went to the gym, went to radiation, came home and fell asleep... that was pretty much my schedule.
So only do what feels right. You have the rest of your life to exercise!
