Doctir recommended exercise physiologist. No idea what that is but guessing some who draws up exercise plan. I know what's going to happen there after the first lot of pain/discomfort.
Wife and I have both consulted a physical exercise therapist physio this year and have had excellent results. My problem was that having been on chemotherapy for 15 months I had lost a lot of weight and suffered muscle wasting. During that period I felt rather tired a lot of the time and had become quite frail with no endurance. We have a steep driveway and I used to drive down to check the letterbox!!
This physio determined what I could do (very little) and gave me a variety of exercises to try. I had 3 months from being declared in remission in June to get fit enough to enjoy the trip I was organising for September/October.
I won't say it was easy and most days my knee and shoulder joints ached from the unaccustomed exercise they were getting. However, I knew that if I didn't exercise then I would be unable to do all the walking we were planning.
Its a matter of taking things slowly to start with, doing some specific exercise every day and not giving up. This was all totally alien to me as a person who hadn't done any formal physical exercise for decades. I had been fit enough in a general sort of way through walking in my daily routine, laying bricks and paving stones, building pergolas and decks and climbing ladders, roofs etc to perform maintenance.
So at my ripe old age, after regaining some strength through the exercises I could do at home, I went to the gym. The physio has his office in the gym so was able to guide me in use of the machines.
People at the gym are lovely with no judgementalism being shown to others who don't have the perfect physique.. Body shapes and sizes range from petite through guys who are into body building (trainers) to the morbidly obese, but people just get on with their own exercise regimes.
Wish I had gone to the gym earlier. I believe there is some evidence that exercise is beneficial for people undertaking cancer treatment.
