ABSTRACT:
Apparatus for exercising the inner and outer thigh muscles of an individual which includes a frame having a seat and a weight cage of a weight movable upwardly from a rest position with pivotally mounted leg receiving frames for accommodating the legs of an individual on the seat movable independently in an arcuate path from a predetermined rotary position corresponding to the rest position of the weight by lateral movement of the individual's legs with a chain and sprocket drive for drivably connecting each leg receiving frame to a respective D-shaped cam connected in turn to the weight so that pivotal movement of each of the leg receiving frames from the predetermined rotary position moves the weight upwardly to provide resistance to such lateral leg movement thereby exercising the inner and outer thigh muscles of the individual.
