ABSTRACT:
A sit-up device having substantially the capability to support all types of sit-up exercises is disclosed. The device comprises a mounting base generally for the purpose of securing it to a fixture during use. Another aspect of the device is the adjustable section used to control the horizontal and vertical position of the feet restraining bar. When installed for use, the feet restraining bar remains parallel with the floor. The adjustability is produced by sliding motions between a lever and a base member which allows for greater vertical and horizontal adjustments. Hence the device can support all types of sit-up exercises postures. The mounting base of this device can be secured to any flat surface such as a door structure, house-hold and office furniture, smooth concrete, wood or metallic surfaces.
