Claim:
An exercise apparatus comprising: a base comprising a front part and a rear connected together; a seat part connected to the base; two legs attached to opposite lateral sides of the front part of the base so as to be swingable away from and toward the base while remaining in a horizontal plane; a first mechanism for adjusting a position of the legs relative to the base; a support column pivotally mounted to the front part of the base for being selectively pivotable into an upwardly directed position or a substantially horizontal position, the support column having a sleeve mounted to the front part of the base and a shaft arranged in the sleeve so as to be movable into and out of the sleeve in a telescoping manner; a second mechanism for adjusting a position of the shaft in the sleeve; a head member mounted on an upper end of the shaft; a pair of arms mounted on opposite sides of the head member so as to be selectively pivotable about a horizontal axis into various positions and selectively pivotable about an axis perpendicular to the horizontal axis into various positions so as to change an angle defined by the arms, the arms being securable in the positions; a third mechanism for adjusting and securing the position of the arms about the horizontal axis; a fourth mechanism for adjusting and securing the angle defined by the arms; a pair of exercise units, each exercise unit mounted to a free end of a respective arm; a pair of a fifth mechanisms, each mechanism of the pair of mechanisms provided on the respective arm for mounting and securing a respective exercise unit so that the respective exercise unit is operable to be rotated about a longitudinal axis of the respective arm and secured in desired positions; wherein the first mechanism includes a shaft that extends upwardly through the front part of the base and a gear wheel attached to an end of the shaft of the first mechanism, the exercise apparatus further comprising a toothed rack movably arranged in a longitudinally extending slot in a bottom of the base, wherein the toothed rack is engaged with the gear wheel so that rotation of the gear wheel moves the toothed rack in the slot, and further comprising a pair of link arms such that each link arm is connected between each respective leg and a rear end of the toothed rack.
