A doorway mounted body exercise apparatus has upper and lower horizontal bars bridging the doorway and carrying respective pulleys and, a rearwardly protruding weight set supporting arm which can be swung between either lateral side to the rear of the doorway to accommodate left and right hand hinged doors and can be retracted into the doorway to permit the door to be completely closed while still mounted. Different cabling arrangements enable the weight set to be used as a counter weight for body weight assistance or additional resistance. An upper frame carrying the upper bar is collapsible for removal and storage or to enable a person to walk through the doorway. The lower bar is hinged at one end to the jamb for swinging up against the jamb so as not to obstruct the doorway when not in use. Footpads on the upper frame enable exercising while hanging upside down.

A body exercise apparatus according to claim 9 further comprising means for operatively supporting a resistance set comprising resistance set supporting bar movable between an operative position in which the resistance set supporting bar protrudes behind the doorway and an inoperative, collapsed position, in which the resistance set supporting bar is withdrawn forwards so as not to protrude behind the doorway so as to enable a rearwardly opening door to be closed completely. 11. A body exercise apparatus according to claim 10 wherein respective opposite ends of the horizontal support bar are attached releasably to the respective door jambs. 12. A body exercise apparatus according to claim 1 and for providing, selectively, assistance and resistance to a person exercising comprising; means for attaching a cable to an attachment point of a person's body; a lower horizontal support bar attached at respective opposite ends to respective door jambs at a lower height adjacent a standing exerciser' feet so as to bridge the doorway; pulley means mounted on one of said at least one upper horizontal support bars and pulley means mounted on said lower horizontal support bar; so that a cable attached at one end to the resistance set and at an opposite end to the body attachment point can selectively be passed over one of the upper pulley means and over the lower pulley means to extend upwardly from the body attachment point and downwardly from the body attachment point, respectively, to provide an upward assisting force and a downward resisting force, respectively, for a person performing a body lifting exercise wherein: the lower horizontal bar is hingedly attached at one end to the jamb and releasably attached at the opposite end to the jamb so that it can be swung upwards laterally out of the path of the doorway to extend vertically adjacent the jamb leaving the doorway free for access therethrough. 13.
