Abstract
An exercise device is disclosed having a self-inflating pillow with a compressed state and an expanded state. In an initial position, the pillow is biased in an expanded state, preferably by coils positioned in the pillow cavity. To perform exercises, the user must compress the pillow by applying force on the pillow. A two-way valve is provided on the pillow to facilitate the intake and the exhaust of air through the pillow. The valve can be adjusted to provide variable resistance and lumbar support to the user.
