In Tai Chi (Taijiquan), "Peng" (掤) is one of the most fundamental and important energies (jin, 勁). It’s not just a technique or posture, but an internal quality or dynamic structure that underlies most movements in Tai Chi.

What Is "Peng" Energy?

Peng (掤) is often translated as:

• "Ward off"

• "Expansive energy"

• "Upward and outward buoyant force"
  
  But it’s more than just pushing someone away. Peng is a kind of resilient, springy energy — like a well-inflated ball that resists compression. It's often described as “inflated,” “rounded,” or “balloon-like” force that maintains structure and neutralizes incoming pressure.

  How Peng Is Applied Practically:

  In application, Peng is often seen in movements like "Ward Off Left/Right" in the Tai Chi form.

  If someone pushes you, instead of resisting head-on or collapsing, you use Peng to redirect and absorb the force — maintaining structure without tension.

  It's useful both in yielding and in issuing force (fajin).
