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.

Owner and director of the Kokoro Aikido Dojo: Karl Ruben started Aikido at the age of 13. In his more than 20 years in this art, he has continued his education throughout Europe, the USA and Japan.

He holds the 5th Dan Aikikai and is therefore one of the youngest teachers in Germany with this degree. Since founding his own school over 10 years ago, he has now accompanied the founding of several other Aikido groups in and around Berlin and trained various teachers.

"It is a great joy and honor to watch the development of both my young and adult students. The opportunity to help people gain more self-confidence, an improved body image and an all-round happier life makes me proud and grateful at the same time. It is beautiful to find the right path for every student."
