Trajectory of the Punch with Master Mariusz

In this video, Master Mariusz Steckiewicz explores the true trajectory of the basic ITF Taekwon-Do punch and explains why the path of the hand is far more important than most students realise. Rather than simply extending the arm in a straight line, he emphasises how the entire body contributes to creating speed, power and accuracy within the technique.

A key focus of the session is how sine wave influences the punch. Many practitioners think sine wave disrupts linear movement, but Master Mariusz demonstrates how the natural rise and fall of the body can actually support and enhance the punching trajectory. By understanding how weight shift, knee spring and body drop combine, students learn how to generate a cleaner, more efficient line of force.

One of the most interesting concepts introduced in the video is his 0-1-+1 system for understanding sine wave. This simple framework helps instructors and students picture exactly where the body should be during each phase of the movement — neutral (0), dropping into the down phase (-1), and accelerating into the up-and-forward phase (+1). With this model, the trajectory of the punch becomes easier to teach and far more consistent across different techniques and patterns.

Master Mariusz also highlights the common problems seen in dojangs: punching too early, losing the shoulder line, over-rotating the hips, or creating unnecessary tension in the arm. Through controlled drills and clear coaching points, he shows how to correct these issues so the punch travels precisely along its intended path.

This video is ideal for instructors looking to refine their teaching of fundamental movements and for students who want to better understand how trajectory, sine wave and body mechanics combine to form a powerful and technically accurate punch in ITF Taekwon-Do.
