Fitness, Nutrition, Recovery and Biohacking.
One retreat. One experience.


A unique experience around fitness, and how to get the best benefits for your health.

Fitness can be one of the strongest levers for longevity and health. 

During the retreat, you will practice various types of training (cardio, HIIT, calisthenics) but also learn how important nutrition is. You will enjoy the local cuisine, day excursions, and learn techniques on how to improve recovery and general well-being. You will also experience the power of connecting with nature and how to biohack your life with the help of our collaborators Bahe and FlexBeam.

If that sounds all too much do not worry. If you are new to fitness, you will have the opportunity to practice with people who are experts on the field. If you are already a fitness veteran you will also have the opportunity to learn many things and fine-tune your exercise plan.

The retreat will take place in Naxos, Greece at a magnificent estate. HiddenHillNaxos is located on a hidden hilltop, with magnificent views of the Aegean Sea and the islands. Modern architecture, simplicity and nature set up an authentic slow living getaway.



I am Juergen (56) from and I will be your coach.  

With over 25 years of experience in the industry, I am very excited to be part of such a retreat as I believe working face-to-face with people is the best way to have a positive impact. 

One of main goals for the retreat, is to have fun with you.

Through the holistic combination of physical training, mindfulness and nutrition I will help you achieve a healthy lifestyle which has a lasting positive influence on you.



I am a certified N1 Precision Nutritional coach, EREPS Personal Trainer and founder of ketOntrack. I am passionate about health and helping people around the world to get back on track.

“I am personally engaged with all the people who trust me to help them change their lifestyle, throughout their journey to gain the experience, knowledge and belief to support their life-transforming habits.”

As a coach, I believe having more energy and feeling better is key for going after your goals. To achieve this, I take a holistic approach to health based on nutrition, fitness, sleep, recovery and connecting with nature.

I have been doing keto, yoga and calisthenics for almost a decade now and have been coaching clients to experience the same benefits that I got from this lifestyle. 

Join me and I will share with with you all my experiences that transformed my life and so many others too.
