No not really At1, other than the fact I have just embraced, going and doing, my work outs, which are a lot of different basic and not physically too hard to do, just a lot of them to remember. It is a little different from going to a gym for a grueling work out. My workouts take between 2-3 hours total, and include arm bicycle, regular bicycle, treadmill, weight machine, plus a whole regime of other things, walking, balance and proper breathing. Learning how to inhale and exhale at a rate to get rid of CO2 in the lungs. habits of holding your breathe, are part of that. My diet probably is along the lines of a proper diabetics diet, counting calories, fat, and controlling carbs, which was something I didn't know much about before this. What I need to do now, is add regular walking daily on all my off days of PT, even if it is short walks.
Like anything else, you get out of something, what you put into it. I do my PT with a group that range in the severity of their lung problems. I consider myself pretty lucky, compared to some of the folks who are pretty advanced. Not sure how severe some are other than observing what they are able to do, some are advanced in cancers, others, really advanced in age, COPD, and capability. Some are much younger than me, but seem to be really struggling with some exercises. Many have to do them with oxygen, while I do not. I'm sure many were life long smokers, I never smoked, or drank. Some of the older ones really resist and complain what they know they have to do. I just put it in my mind to do everything, and know that the ones that are hardest of the ones you need to do most.
I loved the holidays, but glad to get back to my program, eating and PT.
