A scientific approach to developing power We are very excited to announce a new collaboration between TKDCoaching and Master Mariusz Steckiewicz. In this first video, Master Steckiewicz presents a live Zoom class to black belts from all around the world. The class is an insightful look at the human anatomy and how it applies to generating more power in Taekwon-Do. There is plenty to learn here, and we are sure you will enjoy it. Because this was a live class, you are also able to join in and train with Master Steckiewicz as he conducts the class.
