wing chun ring

Probably the single most important reason to train with the wing chun ring has to due to the point of rotation. In nature any display of power on a grand scale has to due with Rotation power. (Windmills, Tornados, Whirlpools, Planetary rotation and Planetary orbit, Super nova collapses or expansion etc.)
When using the wing chun ring the hands, and specifically the wrists are in constant contact with the inner circumference of the Ring, this causes the arms to rotate around an artificial pivot point.
First: when the arms move in this way orbiting around this artificial pivot point they have greater mass than they would if the axis of rotation ran through the ulnar & radial bone area. (as well as greater deflection surface area.)
Second: through the rise and fall of the elbow, the arms generate greater power through the second most important element (the first being the change in pivot), Enhanced expansion and contraction of the arms ability to generate Power. This is further amplified through the integrated use of the spine (lifting of pelvis & rounding of the backs scapula), this and adding the bodies mass (through the stance rotation) more than potentially doubles the power produced.
