The Hidden Power of Ji in Tai Chi | Step-by-Step Tutorial on Internal Force

In this video, Susan Thompson demonstrates the internal energy known as Jì (擠) — one of the four primary energies in traditional Tai Chi: Péng (掤), Lǚ (履), Jì (擠), and Àn (按). Often translated as "press" or "squeeze," Jì represents a highly concentrated forward power that is generated through internal structure and coordination, not brute force.

Unlike Fa Jin (發勁), which is an explosive release of force, Jì is a forward-projecting energy that can be delivered in a short distance with minimal external movement. It is a kind of elastic, spring-like power that travels in a straight line through the center, making it especially useful for demonstrating how Tai Chi delivers real-world power without tension.

In this demonstration, Susan offers a full tutorial on how to deliver Jì power. She works with a new student in real time, guiding him step-by-step as he transitions from using muscle force to accessing true Jì energy. The shift is visibly noticeable — his power becomes more efficient and connected once he lets go of tension and begins using internal structure instead of strength.

This is not about speed or muscular strength — it is about directional structure, fascia connection, and mental clarity. Susan’s teaching emphasizes how much power can be delivered at close range through integrated internal mechanics, rather than external force.
