An idiom referring to the striking with the limbs while the central mass of the body remains relatively unmoving.

Comments:

This motion category relies solely upon the speed and mass of the limbs to generate power, while the body neither adds to nor detracts from the enactment of the strike(s).

The resulting maneuver(s) can be used offensively or defensively, and this idiom only describes the

method and not the intent.

The distinctiveness of the these strikes is that a combination of limbs is used to enact the it. This can be both arms (any plane) or an arm and a leg (more typically on a vertical plane). The multiple limbs are used to counter-balance each other, which can allow for fast accelerations of the striking limb. This correctly implies that the limbs typically either travel in reverse directions or complement each other through an offset in a counter-balancing distance (e.g. opposite points in relation to the centered mass).

This type of maneuver, like most other maneuvers, can be executed on vertical, horizontal, or diagonal planes; and can be circular or linear.

Vertical strikes tend to have the body relatively motionless; with just balance compensations added as needed (Body English). One common way in which this type of strike may be employed is during the initial move of the cross-out and cover using the step of the maneuver (e.g. the leg) to counter-balance the striking element of the maneuver (e.g. the hand, wrist, etc.).

Horizontal strikes can optionally use some degree of Body Rotation to (mainly) help in the alignment of the strikes.

Diagonal strikes can take on any or a combination of the characteristics of the vertical or horizontal options.

The strikes generated from this type of motion can either be stiff (see Body Fusion) or loose (see Whip). Generally speaking, stiff strike are more often associated with vertical striking, where horizontal striking  can be associated with either method.

The best example of the whipping (horizontal) version of this type of strike is the child's game where a stick has two (2) strings with a ball tied to each end. By spinning the stick back and forth between the hands (vertically oriented, but horizontally spinning), the balls are propelled around the centered mass of the stick.

These motions are reminiscent of long-fisted kung-fu.

Technically speaking, Mid-Point Balance can differ slightly from this concept in that Mid-Point Balance may engage any movement of the body to assist in enhancing the enactment of the maneuver, but that is not a requirement. Other than that small detail, these terms are the same.
