An upper body exercise apparatus to assist an exerciser to do chin-ups and dips. The apparatus includes a frame having a base, a platform parallel to the base for the exerciser to stand on, chin-up handles and dip handles extending from the frame, a system to oscillate the platform vertically between a lower position and an upper position while maintaining the platform parallel to the base and while avoiding any angular or horizontal displacement, a pneumatic cylinder for providing a force to the oscillating system which is opposite the weight of the exerciser, and a control and monitor whereby the force is controlled and the oscillation of the platform is monitored. |
