An exercising apparatus is disclosed which simulates stair-climbing. In order to reduce breakage problems in the force-transmitting structure between each pedal and a one-way rotating drive shaft, a pair of pulley wheels, each associated with a pair of cables, are used. Each pulley wheel rotates the drive shaft, and is pulled in one direction of rotation by a pedal-connected cable, and in the other direction of rotation by a cable connected to a return spring. Each cable on each pulley wheel reels into and out of helical grooves formed in the periphery of the pulley wheel.

In an exercise apparatus which simulates stair climbing, which has a rotating resistance mechanism, and means for causing rotation of said mechanism as a user steps alternately on a left foot pedal, moving it from an upper to a lower position, and a right foot pedal, moving it from an upper to a lower position, a force transmitting structure between the pedals and the resistance mechanism, comprising: a driving shaft rotatable in one direction only; a member which rotates with the driving shaft to cause rotation of the resistance mechanism; a first pulley wheel mounted on the driving shaft and arranged to apply torque to the driving shaft when the first pulley wheel rotates in one direction, and to free wheel on the driving shaft when the first pulley wheel rotates in the opposite direction; a first cable connected at one end to the left foot pedal and at the other end to the first pulley wheel, said first cable applying torque at the first pulley wheel to rotate the driving shaft when the left foot pedal is moved from its upper position to its lower position by the user\s weight; a first pedal-returning means for automatically returning the left pedal from its lower to its upper position when the user\s weight is removed from that pedal; a second cable connected at one end to the first pedal-returning means and at the other end to the first pulley wheel, said second cable applying torque to rotate that pulley wheel but not the driving shaft; a second pulley wheel mounted on the driving shaft and arranged to apply torque to the driving shaft when the second pulley wheel rotates in one direction, and to free wheel on the driving shaft when the second pulley wheel rotates in the opposite direction; a third cable connected at one end to the right foot pedal and at the other end to the second pulley wheel, said third cable applying torque at the second pulley wheel to rotate the driving shaft when the right foot pedal is moved from its upper position to its lower position by the user\s weight; a second pedal-returning means for automatically returning the right pedal from its lower to its upper position when the user\s weight is removed from that pedal; and a fourth cable connected at one end to the second pedal-returning means and at the other end to the second pulley wheel, said fourth cable applying torque to rotate that pulley wheel but not the driving shaft.
