ABSTRACT:
A thigh exerciser includes a pair of horizontal first and second swing rods each having a pivot end portion connected pivotally to the seat member, and a thigh-engaging portion disposed outwardly of the seat member. The thigh-engaging portions of the first and second swing rods can be pressed toward each other. A biasing damper includes a piston disposed within an inner chamber in the pivot end portion of the first swing rod, a fluid filled within the inner chamber, and a resilient member for biasing the piston to move within the inner chamber in a first direction. The piston is connected to the pivot end portion of the second swing rod such that pivoting movement of the first and second swing rods toward each other is converted into movement of the piston within the inner chamber in a second direction opposite to the first direction.
