An apparatus includes a handle member that has a grip portion and a coupling portion. In one embodiment, the grip portion is removably coupled to the coupling portion. The coupling portion is configured to be slidably coupled to a tension member such that the tension member may slide with respect to the coupling portion from a first portion of the coupling portion to a second portion of the coupling portion. In one embodiment, the travel distance of the tension member from the first portion of the coupling portion to the second portion of the coupling portion is greater than 2 inches (5 cm). In another embodiment, the grip portion includes a vertex location. A first axis is defined by the handle member and extends from the vertex location to the first portion of the coupling portion. A second axis is defined by the handle member and extends from the vertex location to the second portion of the coupling portion. In one embodiment, the angle defined by the first axis and the second axis is greater than 5°.
