Utilizing the principles of physics (mass and leverage) and body mechanics, the intent and design of the Ergonomic Body Developer (EBD) is to harness the effects of torque at a given distance from a fixed pivotal point. Other systems require a force (mass) to be applied at the most distal point of the levering appendage (typically the extremities). The EBD is designed to distribute said force equally over the entire levering appendages concurrently with the variability of the masses to gradually condition the body to greater exertion and stamina, reducing or eliminating collateral damage due to overzealous miscalculations. It is designed to target specific muscles or muscle groups and to eliminate the necessity of specialized equipment. The EBD utilizes natural, body motions in such a manner that each activity becomes an exercise. The key is the vast variability of the masses and their interchangable positionings on the body.

A forward/reverse mechanics calculation of an accurate model of a human body having bone geometrical data and muscle/cord/band data is carried out at high speed. When a new skeleton geometrical model is given, a mapping between the new skeleton geometrical model and a pre-defined normal body model representing a normal body is defined to automatically produce a new body model. A processing unit reads model data to be subjected to mechanics calculation, reads a produced force f of a wire/virtual link exerted on the body model, reads the angle, position and velocity of the current rigid body link, calculates the Jacobian J_L of the length of each wire concerning the joint angle, converts the read produced force f of the muscle/cord/band into a generalized force τ_G according to the defined Jacobian J_L, stores the generalized force, determines the acceleration of the whole body of a motion produced when the generalized force τ_G is exerted on the body and calculates the velocity and position of each rigid body link, and stores them.
