Mark Your Calendar: February 2026 in Horsens
In February 2026, ITF Denmark welcomes practitioners to an extended black belt and national training seminar in Horsens with Master Robert Boer from the Netherlands. With a strong focus on sparring and practical self defence, and sessions for both black belts and color belts, this weekend promises high level training, technical development, and inspiration for all dedicated Taekwon Do students.
Better Questions, Better Black Belts
In Taekwon-Do gradings, we often assess physical skill, high kicks, fast movement, board breaks, but true mastery goes beyond performance. When we ask thoughtful, open-ended questions at gradings, we transform tests into meaningful learning moments. Reflective dialogue invites students to understand why they train, how the Five Tenets truly shape their character, and where their journey is headed. By encouraging self-awareness and honest reflection, instructors help practitioners become technically stronger, mentally resilient, ethically grounded, and self-directed. Better questions lead to deeper understanding, and deeper understanding builds better Black Belts.

Hosinsul on Gradings: Technique, Safety, and Fair Assessment
In this article, Roy Rolstad of ITF Radix clarifies how Hosinsul (self-defence) should be structured and assessed during Taekwon-Do gradings. Emphasizing technique, clarity, and safety, the piece explains why controlled, predictable execution is essential, especially when evaluations involve joint examiner panels and candidates from different clubs. Realism in training has its place, but fair assessment depends on shared standards and preparation.

The Dilemma of Realism: Should Taekwon-Do Teach Real Violence or Remain Family Friendly? A balanced argument for instructors in modern Taekwon-Do
Taekwon-Do instructors face a real dilemma: should daily training focus on preparing students for real-world violence, or remain a safe and family friendly martial art? Using data on how violence actually occurs, this article argues for a balanced approach. Realistic self-defense belongs in controlled courses, seminars, and adult classes, while everyday Taekwon-Do should prioritise community, confidence, technical quality and long-term development. The art stays authentic, and the dojang stays welcoming.
There is more than meets the eye: ITF Radix in the UK
When ITF Radix visited London/Wokingham, we saw how Taekwon-Do can transform: familiar drills became dynamic self-defence responses, and patterns you know by heart suddenly gained new purpose and clarity. Under Master Robert Boer’s guidance, questions that many practitioners carry for years finally found answers: How do we make Taekwon-Do our superpower in real-world conflict? How can we turn technique into instinct? The evening left everyone with fresh eyes, deeper understanding, and an appetite for more.
The shared technical DNA of Taekwon-Do, Judo and Karate
This article explores the shared technical dna between Judo, karate and Taekwon-Do by comparing the two hand mechanics that drive all three arts. Tsurite and hikite in Judo match perfectly with jirugi, terigi, makgi and dangison in Taekwon-Do. The result is a clear understanding of how both systems use the same pulling and guiding engine to break posture, control structure and finish techniques with power and precision.
TCB ⚡️ – Taking Care of Business: The Warrior Mindset Elvis Left Behind
A personal reflection on the meaning of TCB, Taking Care of Business, and how Elvis Presley’s martial arts journey shaped the motto that inspired millions. From training in Germany and under Korean master Kang Rhee, to influencing Western martial arts culture, Elvis lived by a code that still resonates today. For me, TCB is part of my childhood, my family, and my martial arts path.
General Choi Hong Hi – A Peace Profile
A recent academic study offers a new perspective on General Choi Hong-Hi, presenting him not only as the founder of ITF-style Taekwon-Do but as a leader who intentionally built peace, ethics, and character development into the art. The authors argue that the Oath, the Tenets, and the structure of training were designed to teach self-control, reduce conflict, and connect people across cultures. Despite the contradictions in Choi’s life, the article concludes that his deeper legacy is a moral project aimed at shaping better individuals and fostering global understanding through Taekwon-Do.

In this reflection, he shares how such a simple routine can build discipline, clarity, and balance, both in training and in life.
From Hanja to Hangul: Roots and Branches of ITF Radix
Language and martial arts share deep roots in Korea. Hanja (Chinese characters) preserve the philosophical foundations of Taekwon-Do, while Hangul (the Korean alphabet) makes those ideas accessible to everyone. In ITF Radix, we follow the same principle: return to the root, uncover the hidden applications, and let the art grow into a complete fighting system.
