Abstract: A substantially rectangular, flexible foam-filled cushion, consists of three substantially rectangular, hingeably connected segments: a longest upper segment, which is configured to align with and support a user's upper torso, a shorter middle segment, which is configured to align with and support a user's pelvis/buttocks and upper legs, and a shortest lower segment, which is configured to align with and support a user's lower legs. From the top of the upper segment extends an elastic resistance cord. From the bottom of the lower segment extend two elastic resistance ankle straps and an elastic foot strap. The thickness and flexibility of the cushion are adapted to provide both resistance to bending of the cushion and support for the portion of the user's body engaged with the cushion during bending. Therefore, the cushion is adapted to play an active role in the exercise movements, along with its appended resistance bands.
