Abstract
Abstract An exerciser device is provided for exercising various parts of the body, particularly the back and legs of a person using the device. The exerciser device comprises a back support on which a person may lie and a ladder member having an end extending over the person. The device may further comprise an upright support for supporting the extending end of the ladder member. The extending end of the ladder member is adjustably connected to the upright support and the other end of the ladder member is pivotally connected to the back support. The ladder member has variably spaced rungs extending along its length on which a person may ''''walk'''' his legs to increase the flexibility and movement of his back and legs.
