This invention relates to an exercise stair device and in particular to one mainly including a base having a cavity at the bottom and a raised portion with two recesses, two inflatable balls each disposed in a corresponding one of the recesses and being communicated with each other via a U-shaped tube, a cover engaged with the cavity of the base, and two pedals pivotally mounted on the base and each having spherical protuberance at the bottom adapted to be received in the corresponding one of the recesses of the base, whereby when one of the pedals is pressed downward on the corresponding inflatable ball, the inflatable ball will be squeezed by the pedal thereby forcing the air in the inflatable ball to go into the other inflatable ball and therefore lifting the other one of the pedals.
