BACKGROUND OF THE INVENTION

There have been many exercise machines proposed for exercising the abdominal muscles. Some have been designed for exercising the main and lower abdominal muscles. Others have been designed for exercising the oblique abdominal muscles.

After considerable research and experimentation, the abdominal exercise machine of the present invention has been developed to not only exercise the main and lower abdominal muscles, but also to exercise the oblique abdominal muscles. A ball and trampoline accessory is also provided which can be detachably connected to the exercise machine to add enjoyment to the use of the exercise machine, thereby fostering more exercise workouts.

SUMMARY OF THE INVENTION

The abdominal exercise machine of the present invention comprises, essentially, a fixed frame, a seat is pivotally connected to the frame by a first hinge and a back support is pivotally connected to the seat by a second hinge. An adjustable platform assembly is mounted on the frame and is operatively connected to the seat, whereby the angle of the seat can be adjusted, to thereby affect the difficulty of the exercise.

A pair of arms are pivotally connected to the frame so that the arms cannot only move straight back and forward when exercising the main and lower abdominal muscles, but also diagonally when exercising the oblique abdominal muscles. Resistance to the movement of the arms is provided by a torsion spring connected to the arm pivots.

The back support, by means of the second hinge, lifts the user while learning back and also assists the user on the sit up. The back support includes a pair of bolsters which not only support the back of the user, but also provide a massage effect to the user\'s back while exercising.

The exercise machine is also provided with an accessory comprising a shaft having one end detachably connected to the exercise machine frame and a trampoline type target connected to the other end of the shaft spaced outwardly from the seat. A medicine ball is provided for the user to toss and catch when thrown at the target.
