An exercise device includes two hand-held grips that generate a pneumatic force that opposes reciprocating movement. Each hand-grip has a piston that moves within and relative to a cylinder. An air outlet associated with each cylinder can be adjusted to adjust the pneumatic force generated by reciprocation. The higher the pneumatic force, the more work is performed to reciprocate the hand-grips.
