For maximum performance in the gym: RSG Group and ESN announce exclusive partnership
The Quality Group, known for its brands ESN (Elite Sports Nutrition) and More Nutrition, and the RSG Group, operator of the fitness studio chains McFIT, JOHN REED, and Gold’s Gym, announce an exclusive partnership. As of January 1, 2025, ESN will be present in RSG Group studios as a provider of protein products, dietary supplements, and beverages. The collaboration starts in Germany.
Strong cooperation with German market leader
In total, ESN products will first be available in 212 studios in Germany. Austria and Italy will follow. “With this strategic partnership, we are sending a clear signal for quality in the field of functional foods. The collaboration is a perfect fit, as both ESN and the RSG Group stand for passion and innovation in the fitness industry. Our members benefit from high-quality products that help them achieve their goals,” says Hagen Wingertszahn, Co-CEO of the RSG Group. “Our studios stand for a holistic fitness experience. With ESN as an exclusive partner, we can offer our members not only first-class training conditions but also targeted sports nutrition directly on site,” adds Sascha Linz, VP Sports & Fitness at the RSG Group. The cooperation will be accompanied by a targeted marketing strategy. In addition to social media campaigns and advertising in the studios, three major events are planned in RSG Group studios, among other things. Influencer campaigns and employee training will also support the partnership.
“Our heart beats for sports – that’s why we develop our products together with world-class athletes and their coaches to elevate performance to the next level. With the RSG Group, we bring this expertise directly to the community and create a space where the ESN spirit can be experienced. Here, members not only surpass themselves but also grow together towards their goals,” says Philipp Markmann, General Manager ESN.
New target groups, new impulses for the industry
The partnership provides new impetus for the sports nutrition category: “With this cooperation, we are making functional nutrition accessible to even more people – directly where they train and work on their goals. This makes sports nutrition more suitable for everyday life and reaches people who eat consciously and want to increase their performance – regardless of their fitness level,” explains Mary-Jo Slipek, CCO The Quality Group. The exclusive collaboration between ESN and the RSG Group marks a significant step for both companies and the industry as a whole – and promises a sustainable further development of the offerings in the studios.
