Athletic Rhy Club (ARC) is the first premium boutique fitness club in Schaffhausen. Inspired by the endless flow of the Rhine or “Rhy” as locals call it. Just as the river has powered the region’s economy for centuries, ARC channels that same energy into health, strength, and community.
At ARC, our mission is to bridge the gap between health and fitness by empowering people to move beyond simply feeling good toward living active, balanced, and connected lives. We create experiences that strengthen the bond between health, community, friends, and family, building a lifestyle where this mindset is shared, sustainable, and inspiring.
High-impact small group training for fast, measurable results. Master your movement with expert-led HIIT, functional fitness for HYROX and CrossFit, and structured running programmes designed to elevate your performance.
Focused on specific goals & building strength in key areas, strength training activates the essential building blocks to support performance.
Low intensity, building aerobic capacity and recovery. Aiming to restore both the nervous system and the muscles while actively building endurance. A foundation to lifelong fitness.
We are humans. We love being among driven, like-minded people. We create a space to share values and ethos that foster bonds that go beyond reps and sets.
Four interconnected disciplines, each one amplifying the others. Together, they form a complete system built for the way you actually live.
For two decades, Schaffhausen native Marco Kern lived the life of an elite competitor, capturing six Swiss championship titles, representing Switzerland internationally ten times, and racing in the World University Games final in Kazan. Today, he channels that high-performance drive into ARC, balancing elite-level programming with the welcoming spirit of a community leader.
A well-connected figure in Swiss sports association, Marco previously captained the adidas Runners Zurich community and co-founded the Schaffhausen-based running company, Runaissance. Outside work and the track, he enjoys life in Schaffhausen with his partner and their son.
