Patent ID: 8100816

Claim:
A training device comprising: a harness to attach to an ambulatory user; an elongated shock absorber connected to the harness to absorb compressive and expansive forces exerted linearly along an axis through the elongated shock absorber on the harness at least in part by the ambulatory user; a pair of wheels extending from opposite sides of a crossbar, the wheels being sized between 8 and 24 inches in diameter to roll and absorb shock from a terrain over which the ambulatory user moves; a weight holder connected between the crossbar and the elongated shock absorber, the weight holder comprising a center bar to hold one or more removable weights for providing weighted resistance to the ambulatory user; and an adjustable hinge that connects the center bar at a desired angle to the elongated shock absorber, the desired angle causing the center bar to be directed downward to the crossbar relative to the elongated shock absorber, the adjustable hinge allowing the training device to be folded about the adjustable hinge to a storage angle that provides the training device in a contact shape, wherein the elongated shock absorber can touch the crossbar.
