The Fitness Center on the Dream was fine. My 19 yr old son used it every day. He never had any problems getting on a cross trainer (they have those, treadmills and bikes - then Nautilaus type weihts in another room). They are small, but clean. They do have exercise classes offered and a jogging track on Deck 7. My son lost 3-4 lbs on the cruise - unbelievable. But I think the rest of us put on a few #'s too many. Enjoy!
