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.

What is claimed is: 1. An exercise apparatus comprising:a handle bar;a resistance assembly, coupled to the handle bar, the resistance assembly includinga housing having first and second opposed parts, each part having an inner face and an exterior, the resistance assembly permitting rotational movement of the handle bar about a rotational axis upon the application of a force to the handle bar; anda resistance mechanism configured to resist rotational movement of the handle bar about the rotational axis;a screw, mounted so as to have a long axis coinciding with the rotational axis, and engaging with a threaded receptacle, for adjustably compressing the spacing between the inner faces and modifying resistance of the resistance mechanism to the rotational movement of the handle bar, one of the screw and the receptacle being coupled to an adjustment knob by which may be provided a user-defined resistance setting of the force required to cause rotational movement of the handle bar;a clamp, coupled to the housing, configured to removably attach the exterior of the first part of the housing to a member that is distinct from the exercise apparatus;such that a user desirous of exercise can grasp the handle bar and cause motion of the handle bar about the rotational axis by applying to the handle bar the force corresponding to the resistance setting and the clamp can be utilized without operation of the adjustment knob.
