What  is  Aikido?

Aikido Lernen

Aikido is a Japanese martial art that focuses on the principle of harmony. Unlike many other martial arts, Aikido does not emphasize attack, but rather the skillful use of the opponent's energy. Practitioners learn to move fluidly, redirect attacks and bring the attack under control without injuring the opponent.

However, the benefits of Aikido go beyond physical self-defense. Regular exercise improves physical fitness, coordination and flexibility. Aikido also promotes mental balance and emotional control as it aims to transform negative energy into positive actions. This martial art not only creates physical strength, but also promotes respect, community and the ability to resolve conflicts in a peaceful manner. Aikido is therefore not only effective self-defense, but also a journey to personal growth and inner peace.

Frequently  asked  questions

1. I'm a complete beginner. Will I be in the way of others?
Our approach is aimed at making it as easy as possible for new members to get started. For this reason we offer separate lessons for beginners and advanced students. In the beginners' lessons you will be gently introduced to new movements, while the explanations are clear and precise. Advanced students have the possibility to train more intensively together in separate lessons. This means everyone can practice at their current level.
2. From what age can children train with you?
We have lessons for preschool children ages 4 and up. The children practice separately in groups divided by age so that we can adapt the content of the lessons to their development. Our children's program, specially developed according to the most modern pedagogical principles, has something suitable for every age group.
3. I'm a little older. Am I perhaps too unathletic for Aikido?
No, you're not. Aikido is not a competitive sport. Each person can practice at their own pace, regardless of age. The goal is to strengthen body and mind. The classes are aimed at gradually building stamina and strength. Practicing in a way that is gentle on the body is a basic principle in Aikido. Depending on your needs, training can range from slow and relaxed to sweaty and demanding. Either way: We will accompany you on this path.
4. Is the training dangerous - can I or my child get injured?
Aikido is a gentle martial art that emphasizes cooperation. The integrity of the body is a fundamental principle in our practice. Partner exercises are always carried out in a controlled manner and there is no sparring. This means that training always takes place in a controlled environment.
5. Are there specific classes held in English available?
We don't have separate classes for English speakers. But our entire teaching staff does speak English. So if there is someone on the mat who is not comfortable with German (which is most of the time), we will always switch back and forth between German and English. Rest assured: Making the class available and comprehensible for you is a priority for us.
6. Does Aikido really work? Can I use this to defend myself?
At first glance, Aikido appears almost dance-like with its flowing movements. That's why the question of functionality can quickly arise. However, the Aikido approach is deliberately not about teaching someone how to fight, but rather how not to fight. Although the movements can basically be used as self-defense techniques, the focus is not on fighting, but on communication. Through the movements you develop physical self-confidence, which exudes calm and serenity. The ability to communicate confidence with your own body is far more important than any technique and will avoid the fight entirely when in doubt.
7. Why are there no competitions or sparring in Aikido?
The basic idea in Aikido is that communication and cooperation bear more fruit than confrontation. We learn this on a physical level, as the techniques become easier the more we work with our partner instead of against them - or even dominating them by force. This philosophy contradicts concepts of victory and defeat. To achieve a more peaceful world, we start with ourselves on the mat and support each other in learning instead of fighting against each other.
