1. An unweighting system for use with an exercise device, comprising:

  • a frame including a cross member, a right leg, a left leg, a right upright bar and a left upright bar, wherein a spacing between the right leg and the left leg along the cross member is at least as wide as the exercise device whereby the right leg, the left leg and the cross member encircle a portion of the exercise device wherein the frame is configured such that a user gains access to the exercise device by stepping over the cross member and passing completely between the left upright bar and the right upright bar;

    a left cantilevered arm assembly extending from the left upright bar, a right cantilevered arm assembly extending from the right upright bar, each cantilevered arm assembly including a cantilever arm having a proximal end attached to one of the upright bars and a distal end configured to receive and couple to the user;

    a left resilient member extending between the left upright bar and the left cantilever arm and a right resilient member extending between the right upright bar and the right cantilever arm wherein the left resilient member and the right resilient member are configured to cooperate to unload a portion of the user'"'"'s weight as the user exercises on the exercise device while coupled between the distal end of the left cantilever arm and the distal end of the right cantilever arm;

    a right height adjustment mechanism having a first end coupled to the right upright bar and a second end coupled to the right cantilever arm proximal to the distal end of the right cantilever arm, the right height adjustment mechanism being configured to receive and couple to the user wherein operation of the right height adjustment mechanism changes a vertical spacing between the exercise device and the distal end of the right cantilever arm;

    a left height adjustment mechanism having a first end coupled to the left upright bar and a second end coupled to the left cantilever arm proximal to the distal end of the left cantilever arm, the left height adjustment mechanism being configured to receive and couple to the user wherein operation of the left height adjustment mechanism changes a vertical spacing between the exercise device and the distal end of the left cantilever arm.
