ABSTRACT:
A pedal exerciser for performing stepper exercises including a pair of pedal cranks, each crank driving one of a pair of crankshafts that are coupled together by bevel gears such that, when one pedal is forced to rotate downward, the other pedal rises thereby providing reciprocating stairclimbing motion. Adjustable resistance to stepping is provided by a resistance pad against either the idler bevel gear or one or both crankshafts. The compact construction is amenable to positioning the exerciser under a desk or table for a seated user. A detachable frame with handles may be attached for an erect user.
