hi, just read your post and I feel for you. I just wanted to say don't be too hard on yourself about maintaining your exercise regime. I too came into having chemo extremely fit and healthy but have found I have had to drop most of my exercising and just managing with the bare minimum, weights occasionally Zumba and cycling occasionally. Winter does not help either. I find my work and family are taking all my available energy. I have been very upset that my fitness levels have dropped significantly. So I just really wanted to say, do what your body can cope with but you need to rest as working and family do take a lot out of you while having chemo.
I had surgery first, now having chemo, then more surgery and finishing off with 5 days a week for 5 weeks of radiation treatment. I am hoping after my last round of chemo Monday week I can get into some serious fitness training before my next lot of surgery.
I have found that after watching Catalyst about exercising before and immediately afterward chemo. I tried it and it actually helped but didn't do it for my last round and found I suffered more from side effects.
