That’s me swimming in the video. I swim 3 times a week. It has worked wonders for my mental and physical health. I’ve dropped 80 pounds, and the water keeps my body temperature down. I also take Aquafit classes which tone individual muscles without over stressing joints.
I’m in better shape in my 50’s with MS than I was in my 20’s! I just require a little more rest in between work outs. :0)
