Injoy Fitness

Injoy Fitness (stylized as INJOY Fitness) is a German fitness studio brand operated as a franchise by ACISO Fitness & Health GmbH. The chain was founded in 2002 in Dorsten by Paul Underberg and has grown into one of the larger fitness studio networks in Germany, with more than 230 studios in the country and over 300 studios across Europe. The brand positions itself around health-oriented strength training, individual support, and sustainable training habits rather than purely performance-driven or low-cost gym concepts. Injoy's offering centers on guided muscle training with personal supervision. The company emphasizes introductory training, individualized training plans, and the availability and competence of its trainers. This positioning places Injoy in the premium or upper-mid segment of the German fitness market: memberships are priced above average, but the brand has repeatedly been recognized in independent tests for the quality of its training support and service. Ownership of the brand has changed over time. In early 2014, a strategic alliance was formed with Genossenschaft Migros Zürich (GMZ) and its German subsidiary Migros Freizeit Deutschland GmbH, which acquired 30 percent of the shares. As of 1 January 2016, Migros took over 100 percent of the shares in Injoy's parent company, Injoy Unternehmensberatung für Fitness- und Wellnessanlagen GmbH. In 2019, the fitness-industry consultancies Injoy and Greinwalder & Partner merged to form ACISO Fitness & Health GmbH, headquartered in Munich. Since 1 January 2022, ACISO Fitness & Health GmbH has been owned by the financial investor Lafayette Mittelstand Capital. Injoy has received positive coverage in consumer tests. It was named test winner in a January 2009 Öko-Test evaluation and again in January 2012 in a test conducted by the German Institute for Service Quality (DISQ) on behalf of n-tv. In January 2014, it received a "good" rating in the magazine test. Stiftung Warentest noted that Injoy charges above-average prices but was rated above average in areas such as introductory training, training plans, and the availability and competence of trainers. Today, Injoy operates as a franchise system under ACISO Fitness & Health GmbH, with its website promoting health-oriented muscle training and personal support under the claim of being a test winner.
