Abstract: An exerciser includes a base supported on a support in a suitable inclined angle for supporting a user. An extension is slidably engaged in the base and has one end extended outward of the base and has a clamping device for clamping the feet of the user to the extension. A bracket is secured to the extension. A lever is pivotally coupled to the base and a handle is secured to the lever for rotating the lever. A cable couples the lever to the bracket for moving the extension outward of the base and and for pulling the feet of the user so as to straighten the spinal column.
