No way, that's awesome!
I was very athletic before I got sick... sports all through college and after, plus mtb, skiing, hiking, etc. I definately feel better when I'm active, my joints don't hurt as much, I'm not as tired and I eat/sleep better. I had a relapse last fall so I'm still coming back from that right now but working out helps a whole lot.
kudos to your friend, it is mentally tough to keep in shape when you have sudden relapses that knock you on your butt for weeks at a time... then you have to start conditioning all over again! Good for her.
