s Health Total Workout in Ten! It is broken into ten minute segments- cardio, upper body, lower body and
flexibility/balance. You can pick out the routine that you want to work on or do them all.
It also gives an alternative set of exercises to do, actually demonstrated by one of the women on the dvd, that are not quite as strenuous. It was around $15 on amazon.
I have also seen dvds specific to MS patients' needs. You might want to look at those, too.
