An exercise apparatus that lies flat on the floor having a back rest rises up when supported by two springs. The lower part of the back and buttocks lie horizontal while the upper part of the back is inclined at an angle to the horizontal. When not in use, the upper back rest folds down flat so that the device can be stored under a bed. The two springs provide back support when the individual is in the reclining position. However, as a person goes from a sitting position to a reclining position, when his or her shoulders contact the back rest, the springs compress and then expand to assist the individual in rising up. The device has two specially designed positionable foot rests with straps to provide a place for the individual to place his or her feet.
