The differential assembly can be implements as an x-bar, lever arm, pulley, gears, or tube. The leg strap arrangement has a knee pad adapted to cover a knee of the user. The knee pad opens along a segment. The upper torso harness has a shoulder strap and buckle. The leg strap arrangement is an elastic material.
