Abstract
This sit-up support device is designed to hold a person's feet when they are performing bent knee sit-ups. Primarily, it consists of a base plate that is rendered stationary to the floor by a clamp that fastens to a door. The device also includes quick-release straps on the base plate, for comfortably holding the user's feet, and a threaded shaft and sleeve are provided in conjunction with the clamp, to force the base plate hard down to the floor.
