If you've been looking into cruises, you've probably seen lots of articles about how you can eat, and eat, and eat! Buffets for all meals, between meal snack stands, formal dining, all-you-can eat dining, and it's all included in the price of the cruise.
Now, if you're the health conscious type--or just trying to maintain your weight--you might be a little concerned about all those temptations, but fortunately all the mainstream cruise ships come equipped with fitness facilities.
When I cruised to Hawaii, I had my choice of cardio machines (treadmills, stationary bicycles, and elliptical trainers), and there was a full range of weight machines. Also, there was a separate hardwood floor exercise room, where classes such as yoga and pilates were offered in the mornings. Or you could just go in on your own time and do some stretching.
If the gym isn't your style, you can also do some laps around the ship to stay in shape. Our cruise ship had a 1/3rd mile promenade walk on a lower deck. It was quite pleasant walking in the morning or in the evening after dinner, especially when we were cruising near the islands and we had a view of the shoreline.
So, to answer this basic question, yes there are fitness facilities on board mainstream cruise ships, and if you want to work off those extra meals, you'll have plenty of opportunity to work out!
