There’s no need to ditch your fitness and wellbeing regime at sea, as our round up of the world’s finest superyacht gyms proves.

Vanish's owners were so thrilled with their new-build 66.25 metre Feadship that their inaugural two-week cruise turned into an entire season packed with four Atlantic crossings. With so much time spent on board, it was fortunate that the owners had the foresight to install a generous gym. They even made tweaks to Harrison Eidsgaard's original design which placed a small gym inside the aft beach club area. Instead, they asked for it to be moved onto the sundeck's enclosed area, allowing it to be larger.

The last thing you might expect to find on board the teak decked, 38.8 metre sloop rigged sailing yacht Vijonara are the superyacht features of swimming pools, Jacuzzis and gyms that have become commonplace on many motor yachts. However, this Hoek Truly Classic yacht has a few surprises up her sleeve and keeps a modest gym down below. Hoek worked together with the owners to design a gym convertible into a single cabin forward of the owners' suite.

Given the rugged exterior aesthetic of the 72.25 metre Abeking & Rasmussen explorer yacht Cloudbreak, it should come as little surprise that she packs a fully-stocked superyacht gym, complete with two exercise bikes, a treadmill and kettle bells. Situated in the beach club, this premium workout space means that guests can enjoy their exercise regimen in close proximity to the water — the option of a refreshing dip is only a few short steps away.

The whole upper deck on this 38 metre Benetti Vivace 125 superyacht is dedicated to the gym. It has state-of-the art equipment by Technogym, including a cross-trainer and a treadmill, as well as a rubber floor to aid with soundproofing. It’s a truly impressive workout space — and with a name like Iron Man, what else would you expect?

When the owner of RH3 set about rebuilding this 40 metre RMK Marine explorer yacht, he paid particular attention to the location of the gym. Situated in the skylounge, the gym takes pride of place on RH3, with two large windows in front of the exercise bikes so guests can enjoy a great view of rolling seascapes as they work out. This comfortable and inviting space features warming woodwork that reinterprets the ribbed expression of rope cladding.

The 74.49 metre Blohm & Voss superyacht Enigma didn’t always have a superyacht gym. It was her second owner Larry Ellison who had this glass-sided workout space added to the main deck aft, meaning inspiring views while you burn off the calories on the treadmill or exercise bike.

Launched in 2014, the Perini Navi-Picchiotti built 73 metre motor yacht Grace E wowed with her upper deck dedicated to wellness with a superyacht gym, spa and beauty salon. This yacht's gym gives virtuous guests the best views on board, with a massive upper-deck gym wrapped in full-height windows. The windows and skylights both let in plenty of natural light as well creating a welcoming space.

Flanked by a sauna, massage room and Turkish bath, the superyacht gym on the RossinaviNumptia, (later renamed High Power III), makes hard work part of a more relaxing spa experience. There is still plenty of high-spec Technogym kit to get in a good workout, but it's a more peaceful setting than your typical high-octane gym atmosphere.

Surprisingly, one of the things most often overlooked on superyacht gym design is having enough headroom to use the equipment. This is solved in the gym aboard Oceanco yacht Nirvana. The 85 square metre space cleverly has a treadmill set into the deck for extra headroom, while many reflective surfaces make the space seem bigger and reflect back the beautiful gym bunnies enjoying a training session.

A yacht gym fit for the world's fastest man. This sprawling exercise space on board the Lürssen superyacht Quattroelle was apparently designed by star Olympic runner Usain Bolt. It sits up top and features a spa pool forward for a post work-out soak to sooth sore muscles.

When owners – and charter guests – spend time on Oceanco yacht Alfa Nero they can roll out of bed and go directly to the gym. This beautiful gym on board the iconic yacht Alfa Nero is part of the owner’s deck at the top of the yacht, making it a self-contained living space — with the best views and top Technogym equipment, naturally.

The gym on the 88 metre Feadship yacht Musashi can be enjoyed al fresco. A large, sliding glass wall and fold-down platform on this lower-deck space create an indoor/outdoor gym adaptable to different weather conditions.
