ABSTRACT:
Longitudinally extensible and shortenable pump poles designed for hand and arm action in dual-action exercise apparatus such as cross country ski exercises and dual-action climbers, treadmills and the like, such pump poles being fixedly attached to the apparatus base rearwardly thereof and manipulated concurrently with or independently of reciprocating leg action. Each pump pole has inner and outer telescoping tubes and an air pressurizable chamber providing greater resistance to pole shortening movement than occurs during pole lengthening movement. Hand and arm movement by the user when reciprocating the pole handles simulates the hand and arm movement of a person actually moving over ground.
