Hi ccasper
Keep up the exercise!!!
I was quite fit before diagnosis running 3 times a week (7km each run)cross trainer and weights at the gym.
Now on ac chemo post surgery - 2 of 4 cycles done with 2 to go then 12 weekly taxol am power walking every day to maintain fitness (no gym due to germs and low white blood cell count). Usually manage 8k each day but immediately after dose is a struggle but like you am determined to keep active. Plus the walking is great to combat fatigue and clear the head. I use the 10 minute rule - if I am not enjoying it after the first 10 minutes I stop but of course I am warmed up by then so just keep going!
Take care x
