An exercise machine mounted above one end of a bed, occupied by a bedridden patient or other supine user, has one or more double-ended ropes, each rope having a handle or a stirrup on each of its ends and a central loop tractively encircling a torque drum. Each torque drum is mounted for rotation against adjustably variable braking torque, which may be canceled in one direction of angular rotation by a one-way clutch. The handles and stirrups have adjustable rope engaging features, achieving infinitely variable rope lengths. Pulleys guide the ropes for substantially horizontal pulling reciprocation by the supine user, whose position may be braced or stabilized by torso-positioning rigid arms, such as adjustable telescoping spacer tubes, extending from the exercise machine to the user.
