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.

Abstract: A muscle training device includes a base seat, a first support arm connected pivotally to the base seat, a second support arm connected pivotally to an impeding unit, and two supporting cushions connected respectively to the support arms. The impeding unit has a housing fixed to the first support arm, a piston unit, first and second fluid chambers formed on two opposite sides of the piston unit, a fluid filled in the first and second fluid chambers, and a passage unit that is in fluid communication with the first and second fluid chambers. The second support arm is turnable toward or away from the first support arm.
