Today, modern fitness centers are much more than just workout spaces. They are experiential spaces, brand environments, and key touchpoints for member retention. An outstanding example of this trend is the John & Janes project, which set new standards over four years ago with its consistent industrial design language. What was considered a bold concept back then is now one of the most important gym design trends worldwide.
Thanks to our high-quality concrete-look surfaces, we created a studio that remains a benchmark for modern gym interior design to this day and impressively demonstrates how architecture, materials, and atmosphere blend into a distinctive overall concept.
Our collaboration with the RSG Group extends far beyond a single studio. Over the years, we have had the opportunity to help shape a wide variety of fitness and training concepts within the group. The RSG Group includes brands such as McFIT, JOHN REED, Gold’s Gym, and High5, among others.
Our mineral concrete surfaces were used in a wide variety of areas: from striking reception and lounge areas to functional fitness zones and Freletics areas, as well as boxing rings, class rooms, and exclusive member lounges. Each concept presented different requirements in terms of design, durability, and brand impact.
In the fitness sector in particular, the environment is a key component of the training experience. Exposed concrete finishes, authentic materials, and distinctive surfaces create an atmosphere of strength, performance, and urbanity. Our long-standing collaboration with the RSG Group impressively demonstrates just how versatile modern concrete aesthetics can be today—from classic gyms and boutique fitness concepts to exclusive premium studios with wellness and recovery areas.


A gym that was ahead of its time
When the John & Jane’s Studio was built, the now-familiar combination of exposed concrete, industrial materials, and minimalist architecture was by no means standard in the fitness industry. The project was among the first studios to adopt this design approach and was an early advocate of a modern gym design that has since become an integral part of many premium fitness studios.
By consistently combining functionality and aesthetics, an environment was created that goes far beyond traditional workout spaces. The striking concrete surfaces, the open floor plan, and the deliberately minimalist selection of materials made the studio a benchmark in fitness studio interior design even back then.
Today, it is clear just how visionary this approach was: Many of today’s modern gym design concepts are based on precisely these design elements.
Concrete Look – More Than Just a Trend
Hardly any other material embodies the values of modern fitness concepts as strongly as concrete. The concrete look in a gym symbolizes strength, authenticity, durability, and a focus on performance—qualities that are a perfect fit for the fitness industry.
The raw aesthetic of concrete lends itself to a wide range of settings, from functional fitness concepts, Hyrox training areas, and modern athletic clubs to the serene atmosphere of the John and Jane’s yoga studio. The material conveys strength, performance, and authenticity.
Today, sustainability is playing an increasingly important role not only in residential and commercial construction—international automakers are also increasingly turning to resource-efficient materials for their showrooms and brand experiences.
Wall Rapture’s mineral surfaces consist primarily of natural rock components and offer a sustainable alternative to solid concrete structures or labor-intensive troweling techniques. Thanks to their light weight, ease of application, and reduced material usage, high-quality exposed concrete finishes can be achieved with significantly lower resource consumption.
One of our current projects in the automotive sector also demonstrates that sustainable design and sophisticated architecture are a perfect match. Renowned automakers are already using our concrete-look wall coverings in showrooms and exhibition spaces around the world to create modern brand environments with an authentic concrete look.
We are particularly proud that one of these projects was awarded the DGNB Gold Certificate in accordance with the strict criteria of the German Sustainable Building Council (DGNB). This award is among the highest sustainability standards in the construction industry and confirms the combination of high-quality design, functionality, and sustainable construction.

However, genuine exposed concrete is often costly, difficult to install, and offers little flexibility. This is exactly where Wall Rapture’s concrete-look solutions come into play. Our high-quality concrete-look wallpapers and mineral wall coverings provide the authentic look of concrete without the structural drawbacks of traditional concrete surfaces.
In the John & Jane project, our finishes were specifically selected to create the gym’s distinctive industrial look. The textured concrete finishes lend the spaces depth and character, while also creating a high-end, modern atmosphere.
Demand for concrete interior fitness concepts is steadily increasing, as more and more operators are realizing the impact that striking wall design has on how a gym is perceived.
Why Modern Gyms Are Designed with Instagram in Mind Today
People today don’t just work out anymore. They share their experiences, their progress, and their favorite spots on Instagram, TikTok, and LinkedIn. As a result, the role of gym design has fundamentally changed. Modern gyms are no longer designed solely for workouts, but also to enhance the brand’s digital visibility.
Interior design plays a crucial role, especially in the boutique fitness, premium fitness studios, personal training studios, and luxury fitness clubs sectors. Members are looking for an environment that fosters motivation, a lifestyle, and a sense of community. Authentic materials such as exposed concrete, mineral wall cladding, and natural surfaces create a high-quality atmosphere that fosters long-term member loyalty and sets the studio apart from the competition.
Recovery areas, wellness lounges, spa areas, saunas, and cold-plunge zones are currently experiencing particularly strong growth. Fitness and regeneration are increasingly merging into holistic fitness-wellness concepts. This is precisely where our textured surfaces, such as Leaf and Jungle, offer an exciting alternative to traditional wall designs. The organic leaf textures create a natural, calming atmosphere and are ideal for modern wellness areas, spa environments, and recovery zones. You can also find more inspiration on this topic in our blog post about designing wellness and spa areas.
But the real shift is taking place in marketing. More and more often, it’s no longer the gyms themselves that are promoting their brand—but their members. Striking exposed-concrete walls, unique textured wallpaper, custom wall designs, and creative space concepts are becoming popular photo spots and social media backdrops. Every selfie, every workout video, and every story thus becomes free advertising for the gym.
Another advantage: Wall Rapture surfaces can be custom-printed or designed with logos, graphics, and motifs. This creates unique brand walls, selfie spots, and Instagram hotspots with high brand recognition. Whether it’s motivational slogans, company logos, or custom images—the wall becomes part of the brand identity and creates experiences that members love to share.
That’s why anyone planning a successful premium gym today invests not only in exercise equipment but also in a distinctive atmosphere. After all, it’s often no longer just the equipment that attracts new members, but the emotions a space conveys—both online and offline.
Recognizable Spaces for Social Media
Especially in the age of Instagram, TikTok, and social media, a studio’s interior design is increasingly becoming a marketing tool. The striking concrete surfaces create photo spots and contribute to a high-end perception of the brand.
Materials & Execution at John and Janes Berlin – Industrial Design at Its Best
The project’s success is based not only on a good design concept, but above all on the selection of the right materials.
Our concrete-look wallpapers and mineral wall coverings were specifically chosen to create the raw and authentic look of exposed concrete. The result is a surface that is visually and tactilely appealing.
Combined with dark metal accents, state-of-the-art lighting technology, and high-quality exercise equipment, the result is an atmosphere that exudes strength and dynamism. The wall surfaces do not serve merely as decoration; rather, they themselves become a central design element of the room.

Design as a Motivational Factor
The design of a fitness center influences far more than just its appearance. A well-thought-out atmosphere can boost motivation to work out, improve members’ well-being, and strengthen their sense of connection to the center. The striking concrete-look surfaces in the John & Janes project create a powerful, focused environment that perfectly matches the character of modern workout spaces. Our concrete-look wallpaper and mineral wall panels play a key role in creating a high-quality atmosphere that motivates members and keeps them enthusiastic over the long term.
Industrial Design with Sustainable Added Value
The John & Janes project is a striking example of just how timeless good design can be. As one of the first studios to adopt this design approach, it embraced the industrial look, concrete aesthetics, and a consistently well-thought-out interior design early on.
Today, these elements are among the most important factors in modern gym design. They create brand recognition, strengthen brand identity, and ensure a workout experience that keeps members engaged over the long term.
With WALL RAPTURE’s concrete-look wallpapers, concrete-look wall coverings, and mineral surfaces, you can professionally bring these very concepts to life. Our solutions combine the authentic look of exposed concrete with ease of installation, exceptional durability, and a visual impact that goes far beyond traditional wall design.
For those who want to actively shape the future of gym design, high-quality concrete surfaces are not just a trend, but a long-term solution for modern, brand-driven, and experience-oriented fitness environments.
