What is the primary function of the 'hikite' hand, the withdrawal of which creates torque?

The primary function of the 'hikite' hand, the withdrawing hand often used in striking techniques, is to generate torque and enhance power by actively contributing to the body's rotation. While the striking hand delivers the offensive force, the hikite acts as a counterbalance and initiates a twisting motion within the core. This twisting motion, or torque, is then transferred into the striking limb, adding significant force to the strike. The hikite also aids in maintaining balance by counteracting the momentum of the striking arm. By pulling the hikite back towards the body, it creates a stabilizing effect that prevents over-rotation and maintains postural control. Furthermore, the hikite prepares for subsequent actions, like guarding or further striking, by returning to a defensive position after contributing to the strike's power. Therefore, it’s active participation, rather than passive retraction, greatly augments striking potential.
