Cruise lines lure travelers with fitness centers, healthy foods and wellness-centric classes

Think cruising is the most unlikely place to find your way to a healthier lifestyle? Believe it's still all about overloaded buffets and extra wide deck chairs to accommodate the girth of the nearly dead and the amorous embraces of the newly married?

Cruise, Baby, CruiseCruising is no longer an excuse to nix your day-to-day smart lifestyle choices - unless you want to. Royal Caribbean went to the head of the class this year when they introduced their Vitality program. Carnival Cruises partnered with Men's Fitness Magazine and began hosting "Mind/Body Cruises" that included nutritional workshops and cooking demonstrations. And don't forget "The Biggest Loser" was filmed onboard the Sapphire Princess in 2006.

If you're hoping to blend your wholesome lifestyle with the flexibility of cruising, welcome to a world where you can have it all. Not leading the healthiest lifestyle at home but think a cruise can help you redefine your focus?  State of the art fitness facilities, a robust list of god-for-you classes like Pilates, spinning and even Zumba (Latino-music inspired dance classes) are just a few of the options you'll find on today's cruise menus.

Have a look at how these cruise lines are redefining wellness-centric cruising.

• Celebrity's "Help, I Don't Belong to a Gym" classes are the perfect way for you wade slowly into a lifestyle change.
• Disney's "Detox for Weight Loss" offers parents a healthier way to while away time without the kids.
• Costa Cruises offers guests who stay in the Samsara staterooms direct access to the Samsara Spa and exclusive use of the Ristorante Samsara.
• Royal Caribbean offers group boxing lessons on the Liberty and Freedom of the Seas ships. On the Enchantment of the Seas you can indulge in a Chi Cruise, the Ultimate Wellness Getaway.

And don't forget that ports of call gives you more opportunity to work off your sins from the midnight buffet. Grab your gear and hike up a mountain, zip-line through a rainforest or boogy-board for an afternoon.

Where was your last cruise? Were you able to balance good-for-you-choices with feel-good indulgences?
