Zumba would be fun on the ship!! The gym would probably be too small to have a good class there though. Maybe up on deck??!? They offer spin & yoga classes in the early morning. And you can use the treadmills, ellipticals & bikes anytime they are open. Even if you don't make it to a class, the gym has an awesome view and it is so cool to run on the elliptical or the treadmill or bike while feeling like you are gliding across the ocean.
Don't know if you know, but a big bonus is that when you use the gym, they provide free chilled water and fresh fruit as well as tea. You are also welcome to use the (much more spacious that your stateroom) showers, robes, towels, lounges and the dry sauna!
The gym was a great way for me to work off all of the yummy food! With the daily exercise, taking the stairs all the time and frequent small meals I actually ended up losing 5 pounds on our cruise!!! And I ate EVERYTHING that I wanted!!! Can't wait to go back on
