Abstract: Devices and related methods of use for providing repetitive spinal extension exercise. The device includes a frame extending between a foot end and a head end, a footrest member at the foot end of the frame, and a horizontal seat member between the foot end and the head end of the frame. A height-adjustable back pad fulcrum is attached to the frame between the seat member and a pivoting post is attached to the head end of the frame. The pivoting post is positioned behind the back pad fulcrum, and may be biased to default to an acute angle relative to the seat member. The pivoting post may include a back roller or pad attached thereto (e.g., near a top end thereof) so that a user seated on the seat member may press the roller and pivoting post backwards as the user rearwardly extends an upper portion of the torso.
