ABSTRACT:
An exercising device simulating walking up steps. A pair of step treads are rigidly supported at a slight angle on the ends of a pair of step arms pivoted at the other ends on the bight portion of a "U"-shaped frame. A rocker plate is connected between the step arms and is adjustably braked by a pair of brake shoes rigidly connected to a cross arm connecting the legs of the "U". The cross arm is selectively attached to different portions of the arms of the "U"-shaped frame together with the rocker plate and brake shoes for adjusting the height of the steps. Support blocks are connected underneath the step treads to provide different angles of inclination of the step treads and accomplished by partial rotation of the blocks.
