<p>A physical training apparatus ( 10 ) has a main frame ( 11 ) having a front portion ( 15 ) and a back portion ( 16 ), an upright portion ( 17 ) spaced from the front portion ( 15 ) and moveable carriage ( 12 ) slidable with respect to the front portion ( 15 ) of the main frame ( 11 ). A cable ( 14 ) is connected by one of its ends to the carriage ( 12 ) and extends from the front portion ( 15 ) to the upright portion ( 17 ). A weight ( 13 ) is pivotally mounted on the upright portion ( 17 ) and is connected to the other end of the cable ( 14 ) and is positioned above the base of the main frame rearward of the front portion ( 17 ), so that a driving force on the carriage ( 12 ) causes the weight ( 14 ) to rise thereby providing resistance to the driving force on the carriage ( 12 ).</p> |
