Claim:
A thigh exerciser comprising: a seat member; a vertical pivot rod; a pair of horizontal first and second swing rods each having a pivot end portion connected pivotally to said seat member by said pivot rod, and a thigh-engaging portion disposed outwardly of said seat member, said thigh-engaging portions of said first and second swing rods being adapted to be pressed and pivoted toward each other by thighs of a user, said pivot end portion of said first swing rod being formed with an inner chamber; a linkage interconnecting said first and second swing rods so as to allow for synchronous pivoting movement of said first and second swing rods toward and away from each other such that each of said first and second swing rods is pivotable between inner and outer positions; and a biasing damper including a piston disposed sealingly and movably within said inner chamber in said pivot end portion of said first swing rod and connected to said pivot end portion of said second swing rod such that pivoting movement of said second swing rod is converted into movement of said piston within said inner chamber and vice versa, said inner chamber being divided into a pair of volume-variable first and second chamber portions by said piston, a fluid filled within said inner chamber in said pivot end portion of said first swing rod, and a resilient member disposed within said first chamber portion of said inner chamber in said pivot end portion of said first swing rod for biasing said piston to move toward said second chamber portion of said inner chamber so as to pivot said first and second swing rods toward said outer positions.
