1. An exercise device, comprising:
a resistance unit having a connecting gear;
a cable; and
an arm that routes the cable to an actuator, wherein the arm is rotatable relative to the resistance unit about the connecting gear, the arm having a central axis;
wherein the arm includes a control that mechanically disengages a locking mechanism from the connecting gear;
wherein the control is activated by an activation force substantially directed either toward the central axis of the arm, along a length of the arm, or about the central axis;
wherein the control comprises a button, wherein the button is activated by pressing down on the button with the activation force substantially directed toward the central axis of the arm;
wherein the activation force is mechanically converted into a linear force along the arm via a wedge coupled to the locking mechanism, and wherein activation of the button causes the wedge to travel in a direction that causes the locking mechanism to disengage from the connecting gear; and
wherein the activation force is mechanically converted into the linear force along the arm that disengages the locking mechanism from the connecting gear.
