In one embodiment, an exercise apparatus includes a gas spring, first and second proximate uprights, as well as first and second distal uprights. First and second safety bars extend between and are connected respectively to the first proximate and distal uprights and to the second proximate and distal uprights. An elongated platform or bench is disposed above an elongated base and includes a seat portion rotatably connected to a back portion. The gas spring has a lower end pivotally mounted on the elongated base and an upper end adapted for attachment to each of a plurality of attachment locations located on the back portion of the elongated platform. An actuator is operably coupled to the gas spring and adapted to cause the gas spring to move from an extended position to a retracted position thereby lowering or retracting the back portion of the elongated platform.
