Abstract

The invention is an exercise unit having a pair of rigidly connected spaced rails being elevatable at one end to a selectable height to define an incline, and a flat carriage rollable on said rails and having structure including pulley lines and a foot retainer for drawing the carriage and the body of the user upward along the incline by the physical exertion of the user. The rails are separable into upper and lower halves and are connected together in use by a novel tongue and socket structure reinforced with a hook and rod system. On the rails a foot grip is mounted so as to be freely pivotable during an exercise program.
