Self-defense for women


The i-defense concept focuses on women’s opportunities and has the aim of empowering them, so that they no longer regard themselves as victims and stand their ground against potential assailants.


Martial Arts Academy i-defense Essen offers an innovative concept for self-defense which is ideal for women. It is the central idea of this training program to teach the most effective techniques by improving one’s reflexes – there are no complicated patterns and combinations as are often practiced in other schools/courses because reality looks different. Practicing your reflexes helps to avoid surprises and takes the physical possibilities of women into consideration. This program conveys effective techniques, improves your fitness and your mental power.


Alfons Pinders, head of i-defense Essen, whose concept of self-defense and self-assertion has already been realized in many different institutions, developed this cross-training (x-defense). It is based on functional techniques (especially for women) resembling the philosophy of the Israeli Krav-Maga. Women-defense offers opportunities to defend yourself against attacks and intimidation.

40+ Karate and Self-Defense for people aged 40 and above at


Mental and physical fitness through age appropriate training


At i-defense Essen the idea of karate is not, unlike in a lot of other institutions, being focused on the mere physical level or the performance for tournaments but is grounded according to its traditional roots on the three pillars of Karate-Do: self-defense, health and philosophy. Yoshukai Karate is a wholistic system, which is also suited for the aged. At the Martial Arts Academy i-defense a respectful, age sensitive training is offered according to the individual physical condition. The appreciation of age is deeply rooted in Asian culture and is being lived in our dojo.


Our experiences have shown that training leads to a physical as well as mental flexibility. Special exercises from QiGong or Shiatsu enhance and vitalise the flow of energy in the body. Our concept of Karate 40+ is thought by experienced and educated instructors and has already been realised in cooperation with the Sportbund Essen, the coverning organization for all sports diciplines in Essen.

Karate for children and adolescents - self defense

Children and adolescents at i-defense Essen e.V.

Image Image

i-defense is a modern association, the training of which focuses on progressive insights into fundamental aspects of the sciences of sports and education. Especially when working with children a well-directed and progressive training that is suitable for children is indispensable.

I-defense Essen is a member of the Yoshukai Karate International Association which is rooted in Japan and the USA. Due to a close collaboration and a constant exchange of ideas its training always considers the latest state of the art in sports education.

Yoshukai International

I-defense Essen concentrates on age-specific and differentiated practicing rather than on "mass processing" - thus we aim for a balanced and self-confident development of the adolescents.

Surplus energies are channeled and the ability to concentrate is improved. Self-confidence, respect, discipline, fairness and courtesy are developed.

No matter whether frightened or hyperactive, martial arts' training contributes to a balanced and healthy development of your child.

Self-defense and self-assertion are central approaches at i-defense Essen.

Techniques and tactics, behavioral practice and role-play, including simulated dangers, sharpen the intellect and natural reactions. This adds to a natural security which is necessary to adequately respond in everyday conflicts (i.e. on the way to school).

Chanbarra - a sport from Japan

ImageIn addition to its rich offer of courses for children, such as self-defense, self-assertion and Karate, the martial arts academy i-defense Essen also offers sport-chanbarra, which was developed in Japan. Chanbarra can be roughly translated as ‘sword combat' and is practiced with soft, inflated, foam-padded "swords", thus avoiding injuries. Master Tetsundo Tanabe is the inventor of this discipline, which already has filled Japan's adolescents with enthusiasm. Nevertheless, grown-ups have also found a steadily growing interest in this quick sport, which - not at least due to a special gear made especially for chanbarra - guarantees a very enjoyable training in the best possible way for children and adolescents. It trains students' reflexes and strength. Apart from this the students experience a mental education deriving from respect and concentration which play a significant role in Japanese martial arts. The little Samurais soon notice an improvement in their coordination and concentration as a result of this creative exercise. Sensei Alfons Pinders of the martial arts academy i-defense Essen was enthusiastic about the training he observed in Japan and added it as an option in his association. For quite a long time, therapists working with children and adolescents have been using the so called ‘Batakas' (clubs made of foam) as an approach to playfully solve conflicts. Chanbarra offers the opportunity to argue physically but with intelligence.

Chanbarra furthers students' youthful kinetic energy and guides it in the right direction.

Classical Boxing

Boxen in Essen

Boxing is one of the oldest Olympic disciplines and provides a significant fitness program, being both integral and versatile alike. Boxing exercises improve basics like strength, stamina, speed, flexibility, and coordination. Stress is reduced and the ability to concentrate is improved. The training involves all-round programs which increase and preserve students’ power and health. It is suitable for men and women alike. The aim of the competition is to defeat the opponent with technical means which are trained persistently, precisely and powerfully. Competitors fight in official weight categories according to the rules of the German Boxing Federation.


First forms of fist fights probably took place in Egypt around 2000 B.C. In the following 2000 years this first form of boxing spread out over and around the Aegean Sea. In 688 B.C. the first official match took place in the context of the Olympic Games. In ancient Rome “boxing” matches were performed with leather straps and metal thorns (which were attached to the fists) by gladiators. There is evidence that fist fights were also part of other cultures. Modern boxing originated in 18th century England, with its first rules set up by the master fencer James Figg. In 1867 the London Prize Rules of Marques of Queensberry were modified with the result being that the first boxing gloves were used. On 7th September, 1882, John I. Sullivan became the first official boxing world champion according to the rules of Marques of Queensberry.

Today, boxing is a modern and popular sport practiced all over the world. Its effective training results in an excellent fitness level and is suitable for all ages. For a long time now, women have also been practicing boxing and are powerful competitors. Those who learn about the art of “fist-fencing” will be fascinated.

Boxing techniques are also trained in the context of self-defense. A constant repetition of techniques in sparring optimizes their effectiveness which lies in their simplicity.

A training course in boxing is a training course of body and mind – a true challenge in itself.
