Abstract: An apparatus for exercise and rehabilitation includes a carriage which is towed by an operator walking forward. A hitch assembly is couplable between the carriage and a harness worn by the operator. The hitch assembly includes a tow line extending from the harness and a three-pronged attachment couplable between the tow line and the walls of the carriage. The harness has an inner belt adjacent the waist and at least one outer belt worn over the inner belt, the inner belt being wider than the at least one outer belt. Weights may be placed in the carriage to increase the resistance provided by the carriage.
