An upper body exercise apparatus to assist an exerciser to do chin-ups and dips. The apparatus includes a frame having a base (42), a platform (24) parallel to the base for the exerciser to stand on, and chin-up handles (22) and dip handles (20) extending from the frame. A motive device comprising a spring (45) driven by an electric motor (48) moves the platform vertically between an lower position and an upper position while maintaining the platform parallel to the base avoiding any angular displacement. The system further includes a control and monitor whereby the force is controlled and the oscillation of the platform is monitored. |
