Just wanna say that the Dr's can't MAKE you do exercise, that is something that you should do on your own accord otherwise why have a tx... It was prolly just your wording, but I wanted to clarify all the same..
Straight after tx you are up walking the very next day, usually just a lap around the ICU...
Within a couple of weeks, once some of your lines are pulled you then take yourself up to the hospital gym and work either a treadmill or stationary bike, for like 10 to 15 minutes
Once you leave the hospital then it is up to you to keep pushing the envelope so to speak....
I was up to working out for 2 hours on either the treadmill, cross trainer or bike...
Last year I got slack so I am into building myself back up again...
The problem after tx is the side effects of your anti rejection pills on your muscles. Building up is slow and tedious as every muscle kills.... You also have to go back to basics once you stop because your muscles are weakened by the pills that keep you alive...
Breathing wise is fine, you have no problem in that department at all but stamia and muscle is where you find it most difficult....
Once you get into a routine it becomes much easier but as I said before once you slack off you gotta start all over again...
That's been my experience anyway!
