(CNN) — Superlative spas at sea have become a staple of the cruise experience, but recently, a slate of cruise lines have been ramping up ever-more-inventive spa and wellness offerings that expand far beyond the traditional confines of the spa's four walls.
You'll find several lines now integrating a holistic-lifestyle mindset from ship to shore, rolling out more healthful cuisine, Zen-inspired spa suites and health and fitness activities on board, while others are taking spa programming ashore via innovative wellness-themed excursions.
For the ultimate in mind-body balance that steers clear of the overindulgent buffet-and-booze cruise of yore, these 10 wellness trends in cruising are sure to have you feeling more refreshed, renewed and fit than before you stepped on board.
Lindblad Expeditions teams up with Exhale Spa
Kicking off in December, look to Lindblad Expeditions' new four-night "Exploration, Transformation, Mindfulness" voyages to the isles of Mexico's Sea of Cortez aboard the National Geographic Seabird.
The mini-sailings -- designed as a stress-busting antidote to the hectic holiday season in December and January -- are developed in partnership with the Exhale Spa brand.
Activities include morning power yoga on deck; afternoon guided hikes; stand-up paddleboarding, kayaking, or snorkeling outings; and a Core Fusion beach boot camp.
You can round out the day with on-deck shoulder massages and guided meditation classes. Bonus: You can fuel up on an expanded health-minded menu too.
Celebrity Cruises to roll out 'Mindful Dreams' program
This summer, Celebrity Cruises is readying to debut a new fleet-wide "Mindful Dreams" wellness program, in partnership with their onboard spa provider, Canyon Ranch.
The program is set to encompass a selection of spa treatments, instructional classes, and expert-led lectures themed on achieving more mindful and restful sleep patterns both on board and back home.
Mindful Dreams builds upon the line's continued expansion into the wellness realm: In 2015, they also launched a small portfolio of "Wellness Rituals" excursions, focused on fitness, nutrition, spa, and spiritual experiences ashore, like a rainforest yoga outing in Costa Rica.
MSC Cruises debuts Weight Watchers and 'Technogym' programming
The first Weight Watchers-themed cruise debuted aboard MSC Cruises' MSC Divina in May, with a "Rejuvenation Vacation at Sea" Caribbean sailing from Miami that factored in consultations with Weight Watchers staffers, customized fitness regimes, wellness seminars, cooking demos and, of course, Weight Watchers-backed meals; another's already planned for November 2017.
Plus, the line's newest ship, the MSC Meraviglia, features a state-of-the-art thermal suite (touting a salt relaxation room and ice waterfall) in its Balinese-themed Aurea Spa, while their "Wellness Experience by Technogym" debuted fleet-wide in April to offer guests comprehensive wellness programming spanning onboard fitness classes, culinary offerings, shore excursions and stateroom amenities.

Aqua Expeditions to Host Fitness Guru on Mekong River Sailing
Plush river cruise line Aqua Expeditions recently announced that it will host fitness guru Alex Salihin (founder of LEVEL fitness and ambassador for sportswear brand Lululemon) for a four-night December 2017 Mekong River sailing aboard its Aqua Mekong.

The line plans to add on future wellness itineraries too.

Also of note: Regent's 2016-debuted Seven Seas Explorer features an industry-first en-suite spa retreat in its top-level Regent Suite, complete with a sauna, heated ceramic loungers, and unlimited in-room spa treatments from Canyon Ranch.
Seabourn Cruise Line's wellness program with Dr. Andrew Weil
Seabourn introduced a mindful living program in January, in partnership with the line's Onboard Spa by Steiner and integrative medicine practitioner Dr. Andrew Weil.
The onboard programming is executed by a designated "mindful living coach" who leads complimentary classes (like daily yoga and meditation sessions), seminars and events inspired by topics from Weil's books and teachings (like mindful meditation and anti-aging).
Plus, guests can sign up to sail with Weil himself on an annual Seabourn voyage, on which he personally hosts lectures and group discussions.

To round out the integrated wellness experience back on board, cruisers can sign up for a suggested spa pairing at the top-rated Canyon Ranch SpaClub, tuck into a brand-new menu of vegan options and raw juices or sign up for one of the line's yoga, Pilates, or indoor cycling classes, which are free for guests as of May.
