Abstract: The invention is directed to an apparatus for exercising a user's muscles that includes a frame. A platform is attached to the frame, which defines an area on which a user stands. A weight stack is attached to the frame. A lineal shaft is attached to the frame between the platform and the weight stack. A carriage runs on the lineal shaft and is attached to the weight stack by a cable. An extension arm is pivotally connected to the carriage. A handle is attached to the extension arm. The lineal shaft and platform allow the user to adjust the machine to their body by just standing in the position that fits their body. The lineal shaft, carriage, and pivotal connected extension arm provides a resistance curve that fits the user's strength curve.
