A bilaterally gripped multiplanar exercise device that is ergonomically designed to avoid harmful stresses on the user's body throughout a selected range of exercise motion is disclosed. The invention enables the user to perform multiplanar exercise that cannot be achieved with existing devices or perhaps too difficult to do so. These objects are attained by dispersing an attached tension or force vector (i.e., resistance) to act at a selected ratio at each middle finger grip center so that the user's gripping hands, wrists, and forearms can become an ergonomic multiplanar interface of resistance application to the human body.
