Welcome to the Trust-Gym,

the sports academy in Hamburg-Harburg.

We offer a wide range of martial arts and fitness activities for everyone. Sandbags, spacious training areas, steppers, treadmills, and cross trainers are at your disposal as well as a large range of 40 Life Fitness and Techno Gym devices.

Our Gym

In collaboration with trainer Daniel Ravasio, a health check, and an individually tailored training plan will be created, depending on your wishes.

Owner Ayhan Özcelik, a former world champion and 2-time European heavyweight champion, works together with the grandmaster from Thailand and trains his boys accordingly. This is how Thai boxer Robert Varntanian made it to the welterweight championship title within one and a half years.

Even young children and teenagers are introduced to kickboxing and sports karate playfully. They can take examinations for the various belts according to the regulations of the German Martial Arts Organization DKO.

One thing is certain: the sun shines 24 hours a day at the Trust Gym.

Under palm trees and yellow-washed walls, training in an area of 800 square meters is enjoyable. You can expect a familiar, personal, and friendly atmosphere. Many friendly members are already waiting for you and looking forward to getting to know you.

Fitness, personal training and nutritional advice

Work out in a pleasant atmosphere. We offer a variety of fitness and strength equipment, bicycles, cross trainers, treadmills, and much more. Much of our equipment comes directly from the rehabilitation sector, so your health is taken care of.

Is this your first time at the gym or do you want to change your habits? No problem! If you wish, we can draw up an individual training plan for you and introduce you to new exercises and equipment.

We will also be happy to advise you on your diet. Our licensed trainers always have an open ear for you.

After training, you can relax in our lounge area or enjoy making new contacts over a mineral drink at the sports bar.

Martial arts for everyone

Children & Youth Kickboxing

We offer children's karate and kickboxing, especially for our young members aged seven and over. They learn in a playful way from licensed trainers how to control their bodies and treat their partners with respect.

The first successes have already been celebrated, and all participants passed the children's first yellow belt test in kickboxing. Of course, there is also plenty of fun to be had!

For our members aged 13 and over, youth training in kickboxing and Thai boxing as well as classic boxing is offered. This type of sports activity brings balance to everyday life, enjoyment of exercise, and respect for other people.

In addition, having fun during training and being together play an important role in the Trust Gym.

Competitions & Successes

Do you want more than just fitness martial arts? Then you've come to the right place. The Trust Gym regularly takes part in nationwide kickboxing and Thai boxing competitions to compete with other schools.

Whether semi-, light- or full-contact, our trainers will prepare you perfectly. Our academy director has completed over 400 fights himself in the amateur and professional sectors and has enough ring experience to prepare his protégés perfectly. Our Thai boxer Robert Varntanian became the German champion in his weight class in just one and a half years.

With enough ambition, motivation, and commitment, you too can be successful. Our team will help you.

Women’s self-defense & women’s kickboxing

We offer kickboxing and Thai boxing as well as self-defense for women.
Train among yourselves and strengthen your body and your self-confidence.

Many nice girls and women are already looking forward to training with you.

Boxing, kick & Thai boxing for adults

We offer kickboxing and Thai boxing, manager boxing, and classic boxing for adults. Train with licensed trainers, a world champion and European champion, or even a Bundesliga boxer.

With us, you get the best skills for your training.

Several times a year we also invite a grandmaster from Thailand, who holds a workshop in our studio and introduces you to the traditions of Muay Thai.
