For the Bayer 04 CEOs Fernando Carro de Prada and Michael Schade "This partnership is both fitting and ambitious: On the one hand, an international company with over 50 years experience of health-oriented, efficient weight training founded on a scientific basis with in-house machines represents an extraordinary success story. On the other hand, a top German club active all over the world able to use the expertise of the new partner directly to achieve ambitious sporting targets," said Schade.
Michael Antonopoulos, CEO and co-owner of Kieser Training, sees the commitment to a Bundesliga club " as a unique opportunity to associate our sporting concept with such a successful club and to further extend the use of weight training. We are looking forward very much to a long-term and successful partnership."
And for sporting director Rudi Völler the long-term cooperation with Kieser Training represents an ideal development: "Having established themselves as a globally respected and recognised professional provider of weight training since 1967, they have impressively demonstrated their expertise," said Völler. "Kieser Training is a brand established in the minds of people and is synonymous with effective and healthy muscle development. A real constant in a market shaped by temporary fitness fashions and thereby a great partner we can look forward to working with very much here at Leverkusen."
Founded in 1967 by the Swiss Werner Kieser, the weight training chain currently has 158 studios with 283,000 members, which are partly operated as franchise studios. With around 1,700 employees in Germany, Switzerland, Austria and Luxembourg and Australia, every single Kieser Training studio provides professional training management and support as well as a consistent offer based on continuing scientific research. This creates a company personality of unmistakable character with the public.
