A weight training machine has a base with an upright member secured thereto. A trolley is positioned on the upright member to move along its length. A plate is rotatably secured to the trolley to rotate relative thereto. An arm is rotatably secured and lockable in a variety of orientations relative to the plate. A cable is trained around pulleys positioned on the trolley and on the rotatable plate and connected at one end to the apparatus and at its other end to a resistance mechanism. The resistance mechanism through the cable resists rotation of the plate by the user when performing exercises. The apparatus may also include a second trolley positioned to move along the upright member with an arm extending therefrom. The cable may be further engaged around another pulley secured to the second trolley so that the resistance mechanism may resist movement of the second trolley by the user along the length of the upright member in the performance of exercises.
