The center point or line in space of any circular movement.

Comments:

The Power Principle of torque is based upon an Axis of Rotation.

Joints are the most common points on the body where an Axis of Rotation is located.

All external motion of the body is based upon rotation of the joints.  Therefore, no motion of the body can occur without an Axis of Rotation being formed.  One can then conclude that motion of the body cannot exist without the generation of some form of torque.  In other words, even linear moves must have a degree of torque in them in order for them to exist.

During the execution of a strike, power can be increased by simultaneously moving the Axis of Rotation toward the intended target.

Example(s):

Executing a front stiff-arm rising back-knuckle strike demonstrates an Axis of Rotation located at the shoulder.
