France-based private equity firm 21 Centrale Partners has acquired Switzerland's larges health club operator Silhouette Fitness.

The Silhouette estate acquired by 21 Centrale - which it did in association with its Swiss partner company SEC Partners - comprises 22 member clubs and two corporate clubs in Geneva, Zurich and Brussels, catering for 37,000 members.

In 2008, 21 Centrale acquired Club Med Gym (CMG) from Club Méditerranée. CMG is the leading brand in the French fitness market, with 70,000 members across 22 clubs in Paris.

It also operates 32 corporate clubs and runs fitness industry training provider IMF.

The combined portfolios of CMG and Silhouette include 44 clubs in three countries and represent a global customer base of 107,000 members. They are expected to generate aggregated revenue of €80m and consolidate their position through the opening of new clubs.

CMG's CEO, Franck Gueguen, becomes CEO across the combined business.

21 Partners is an international private equity group dedicated to growth buyouts in the Italian and French mid-markets.
