Abstract
Abstract A back therapy and exercise apparatus having a heavily padded horizontal knee bar made of pipe and with the padding formed of resilient foam material such as foam rubber wrapped with plastic, and a padded toe bar in parallel horizontally spaced relation to the knee bar and also made of pipe. A flexible ladder consisting of horizontal pipe sections supported on chains depends from the opposite ends of the knee bar. A trapeze is positioned with its horizontal bar slightly above and spaced laterally from the knee bar, and a rope having knots at spaced intervals depends from the trapeze to permit a user to grasp the trapeze bar, climb the flexible ladder, hook his knees over the knee bar, hook his toes under the toe bar, and lower himself to an inverted position by means of the knotted rope for the desired length of time.
