ABSTRACT:
A stair climbing exercise apparatus for use within a pool of water comprises two steps mounted for reciprocal movement along vertically disposed guides, pulleys disposed at an upper end of the guides, and a cable interconnecting the two steps and extending around the pulleys. Mounted on each of the steps, for movement therewith, is a flap having a relatively large surface disposed perpendicularly to the direction of movements of the steps. In use, when one of the steps is moved downwardly by the foot of a user of the apparatus, the other step is moved upwardly by the interconnecting cable. The water resists movement of the flaps, hence provides resistance to downward movement of the steps.
