1. An exercise apparatus comprising:
- a frame;
a user interface movable between a retracted position and an extended position;
a pneumatic actuator having a cylinder and a piston rod that extends from the cylinder along a stroke axis, the pneumatic actuator being disposed on the frame;
a pulley wheel rotatably connected to the piston rod; and
a cable wrapped about at least a portion of the pulley wheel and having a first cable end and a second cable end, the second cable end being fixed to the frame and the first cable end being coupled to the user interface.

Abstract
An exercise apparatus includes a compact resistance unit that houses a pneumatic cylinder. The cylinder is connected to a pulley wheel that moves at least toward the cylinder. A main cable extends about a portion of the pulley wheel. One end of the main cable is fixed to the unit housing and the other end is attached to a pulley block of a block-and-tackle mechanism. A user cable extends through the block-and-tackle mechanism and is connected to a handle. The pneumatic cylinder resists movement of the handle away from the unit.
