Just another video of a Northern Korean team demonstrating ITF Taekwon-Do. Of course it is all choreographed, but that is after all the purpose of a demonstration of this sort. This particular demonstration goes to great lengths to focus exclusively on fundamental techniques (i.e. basic movements) in action. The fact that some of the boards do not break shows that these are actual hard boards, not the cardboard thin planks customarily used in the demonstrations of other taekwondo version.
Whatever qualms people have about the practicability of ITF Taekwon-Do, including its controversial sine-wave motion, they cannot deny the dexterity, power, and precision that this martial art can instil. But with all things, such feats requires lots of dedicated training.
