Abstract: An exercising device comprising two flexible lines, each line having a stirrup member at one end for receiving a person's foot therein and a loop member at the other end for grasping with a person's hand. The stirrup and loop members are each attached, by means of a slip-knot, onto the flexible lines between knots which are located at predetermined points on the lines. This permits a simple adjustability of the functional lengths of the lines to accommodate persons of different heights. Each of the lines passes over one of a pair of pulleys. A hanger line passes through a hollow tubular spacer and through openings located one at each end of the spacer and knots tied just above those openings. Each of the pulleys has a rotating eye through which the hanger lines passes as it leaves the ends of the spacer. A knot is tied above the said openings at the ends of the spacer thus anchoring each of the pulleys in place.
