This invention pertains to a novel simulated stair exerciser. More particularly, this invention relates to a simulated stair exercise apparatus which is lightweight, portable, and can be converted from an upright position when in use to a compact fully collapsed position which can be stored away. A simulated stair exercise apparatus comprising: (a) a base; (b) a slide frame, a first end of which is pivotally attached to the base; (c) a leg frame pivotally attached to the slide frame at a second end of the slide frame, the end of the leg frame removed from the pivotal end being detachably connectable to the base; (d) a handle pivotally connected to the leg frame or the slide frame; (e) a pair of detachable foot rests adapted to move upwardly or downwardly along the slide frame; and (f) an adjustable tension member which exerts a resistance force on the foot rests and enables the slide resistance of the foot rests to be varied.
