Exercise and physical activity is mandatory
in my book!
Yes it sucks. Yes it can be literally painful. Yes you're sapped with no energy. But my attitude is "suck it up buttercup" because when I do not exercise I can feel myself stiffen and lose mobility.
Having been forced to use a wheelchair for short periods, I can say wheelchairs suck and I don't want to go there; so I suck it up.
For me I stretch multiple times per day. If we were to go out to lunch I might do a fetal position squat after sitting for an hour because my legs can be that stiff. Oh well, I don't care about looking weird, that's what 30+ years of diagnosed MS has taught me to do to stay mobile.
I go to the gym multiple times per week and work out with weight machines, kettlebells, etc. The room at my house I'm sitting in now has dumbbells on the floor (that don't get enough use!). You get the picture -- my attitude is "use it or lose it."
For aerobics and heart-related stuff I do some swimming at the gym but that's sort of a hassle. Everything from the getting dressed/undressed/shower routine to the idea that laps suck out energy in an obscene way.
So my main thing for aerobics is to ride a recumbent trike. My equilibrium is such that sometimes I walk like a drunk, so 3 wheels are needed with a bike. Recumbent bikes are stupidly expensive (any bike/trike will do) but recumbents are amazingly comfortable.
But the ability to peddle like a madman and rest/coast as needed (here in IL the land is flat so peddling is easy) is a godsend. Plus, I honestly think that the varied tasks your eyes are doing when riding a bike -- focusing short-range and distance vision ideas -- are good for one's eyes.
I'm not a "fitness class" kind of guy and I haven't gotten into yoga. Finding the "right" class (that's cheap/free, slow-paced and not run like a drill sergeant -- yes those yoga classes exist!) is a task on my to-do list.
But by all means, ensure you're doing something
for exercise and to retain mobility. Expert doctors in MS and long-time MSers seem to agree: it's a critical component for longevity. Or as one doctor puts it, one of the 4 keys in being 4 for 4
in your struggle against this damned disease.
