摘要： An apparatus for exercising the thigh, hamstring, and groin muscles, including structure for applying a predetermined weight to the upwardly extending leg to thereby stretch the hamstring and thigh muscles of a person lying on his back. The weights are attached to the person''s upwardly extending ankle by use of a cord and pulley system, and a one-way clutch enables the lifting of the weights by use of a cord with the hands and arms, then transferring the force of the weights to the leg to be exercised, thereby relieving the arms of the task of applying the force to the leg. A pair of pads are resiliently retained in laterally spaced relation so that a person using the device may position the pads between his knees and force them together against the resilient force to exercise his leg and groin muscles. A lazy tong device connected to the resilient arms has a curved plate adapted to engage the user''s abdomen to enable the user to apply greater resistance to movement of the pads, as desired.
