Isometric, dynamic isotonic concentric and dynamic isotonic eccentric motorized guidance exercise apparatus

An isometric, dynamic isotonic concentric and dynamic isotonic eccentric motorized guidance exercise apparatus for human muscle development comprising:

• at least one electric motor, said at least one electric motor including an output shaft;
• a drive guidance assembly, said drive guidance assembly secured to said exercise apparatus and connected to said at least one electric motor, said drive guidance assembly includes a bar, said bar secured between said at least one electric motor and a handle of a weight bench;
• at least one tactile feedback interface member, said at least one tactile feedback interface member is a headboard of said weight bench and said headboard is secured to said drive guidance assembly at said handle;
• an assistance and resistance force device, said assistance and resistance force device configured to be secured to a limb or a torso of the human body, the limb or the torso positioned proximate said headboard;
• at least one force sensor, said at least one force sensor calibrated to determine the effort expended by the human muscle to move said assistance and resistance force device;
• and
• wherein energizing said at least one electric motor actuates said drive guidance assembly, said at least one electric motor induces a linear motion in said bar and said handle to raise and lower said headboard relative to said weight bench, wherein said headboard is configured to be engaged by the limb or the torso and said assistance and resistance force device is configured to be actuated by the limb or the torso.
