An embodiment apparatus includes a crossbar including a surface with holes arranged along a portion of the crossbar and a handle including a surface with a hole. The crossbar may be configured to allow the handle to positionally adjust along the portion of the crossbar such that the hole in the surface of the handle aligns with one of the holes in the surface of the crossbar when the handle is located at a position along the portion. Alternatively or in addition, the handle may include a head which defines a plurality of holes in the handle. In this arrangement, a first connector is configured to slidably engage one of the plurality of holes in the handle and the hole in the crossbar, each of the plurality of holes in the first handle defining an orientation of the first handle.
