The thing about “just walk more” with MS is, you don’t want to when it’s a painfully slow lurch to go places. You may have people with you, you may not have unlimited time, you have the risk of falling over.
One of the things I appreciated most about my physiotherapist sessions (not liked, but appreciated) was the stationary exercise machine. It was quite draining, but I think it was the biggest cause of the afterwards good exhausted feel, the feeling that carries over into muscles not being so easily fatigued in the subsequent days.
So I’m thinking of getting one for the apartment. But which? How much? How fancy?
