An exercise apparatus includes a handle bar and a resistance assembly, coupled to the handle bar. The resistance assembly includes a housing having first and second opposed parts, and permitting movement of the handle bar about a rotational axis upon applying force to the handle bar. A resistance mechanism resists movement of the handle bar about the rotational axis. A screw, mounted lengthwise along the rotational axis, and engaging a threaded receptacle, adjustably compresses the spacing between the housing parts and modifies resistance to movement of the handle bar. One of the screw and the receptacle is coupled to an adjustment knob setting a user-defined resistance. A clamp, coupled to the housing, removably attaches the exterior of the first housing part to a member. A user grasps the handle bar and moves it by applying force corresponding to the resistance setting. The clamp can be utilized without operating the knob.
