Abstract
A foldable stair climber exercise machine includes a central frame having a main support beam, a second support pivotally connected to the main support beam, and a cross-member pivotally connected to the second support and removably connected to the main support. Stepping members on opposite sides of the central frame are pivotally connected to the second support and are connected by a flexible linkage. Air cylinders are removably connected to the stepping members and pivotally connected to the frame. Because the frame members are easily disconnected and pivotal with respect to each other, and because the air cylinders are easily disconnected from the stepping members, the disclosed stair climber is easily folded to a flattened assemblage for storage.
