ABSTRACT:
An aerobic exercise machine is disclosed in which aerobic exercise may be conducted using the trunk and hip flexor and extensor muscles. The exercise machine does not require dynamic use of the extremities. The exercise machine provides a uniform level of resistance to contact means adapted to contact both the anterior and posterior surfaces of the trunk of the person exercising. The exercise machine enables exercise by flexion and extension of the trunk muscles and flexion and extension of muscles controlling the hip joint. An energy storage device is utilized to provide uniform resistance to movement in both directions and during the reversal of directions. A counter is provided and various levels of resistance may be selected by switching selected amounts of resistance across the output of a generator driven by the motion of the exerciser.
