Why we built Stronghold
Together with my brother, we opened Stronghold Gym in the Wilhelmsburg. I am a sport scientist and sport therapist, my brother works as a physician. Our goal is to provide the best possible training for each of our members. We start with a comprehensive screening to test different performance and health parameters, then create a tailored training plan from that data. This allows us to support professional athletes, older beginners, and people with physical limitations in the right way. — Felix Schons
Start with a trial session
No experience required. We meet you where you are. Bring comfortable sportswear, a towel, and about 90 minutes.
What happens in the trial session?
We do a short check of your goals and health background, warm up together, cover technique basics, and guide you through an adapted workout. At the end we answer your questions and show you the next steps.
What should I bring?
Sportswear, clean indoor shoes, a towel, and something to drink. Arrive 5-10 minutes early so we can start on time.
Is it really free?
Yes. The trial session is free and completely non-binding. Afterwards you can decide calmly whether you want to continue.
