I am definitely weaker than a year ago. It may be a combination of MS and medication. I take Baclofen and I think a side effect is weakening of the muscles. Don't quote me on that though.

I found a delightful TV workout, 30 minutes per day.

I am not sure anything can really help but it can't hurt either. Just getting on and off the floor is my cardio. But I have a sense of humor about using the bed to pull myself up to a standing position.
