The Studio

Founded in 2007, K4 is one of the first personal training studios in Germany and is still today one of the most sought-after gyms in the city of Frankfurt. In an exclusive, intimate atmosphere, founders Jannis Kanellopoulos and Alex Vieregg offer high quality personal training for up to 150 members, while taking established and innovative training philosophies into consideration.

The gym stands out with its unique atmosphere: cleanliness, fresh indoor air, soft background music and always ready for use equipment, as well as parking in its own underground garage, access code, towel service, permanent locker, water, snacks, smoothies and laundry service.

All the training equipment meet the highest quality standards and operate particularly quietly – a detail you will love!
