Abstract
Abstract A device to allow a person to bend forward and place the upper portion of his body above the pelvic region in an inverted position across a padded support placed in a doorway, while stretching his legs out and away from the padded cylinder in a direction generally perpendicular to his inverted body. The feet of the user are restrained through straps secured to a lower portion of the doorway. The user is able to stretch his legs out away from each other, away from his body, either singly or in unison, and can also swing the upper portion of his body above the pelvic region using the padded support as a fulcrum.
