A resistance training apparatus and method for providing a plurality of training vectors having points of origin variable by direction and elevation to a trainee. The apparatus may accommodate a plurality of trainees and provide multiple training vectors to each trainee. The apparatus provides the training vectors by attaching tethers such as elastic cords to harnesses worn around body portions of an athlete in a configuration that allows the athlete to perform a sports-specific or therapeutic movement at an optimum speed. In one embodiment the apparatus includes a base forming the training area and a pair of tower assemblies, each providing elastic cords for attachment to the harnesses worn by the athlete. In another embodiment the apparatus provides at least sixteen training vectors to a trainee. In yet another embodiment the apparatus provides training vectors to patients or trainees who cannot fully support their own body weight. Each of the elastic cords providing the training vectors are independently adjustable such that balanced or unbalanced loading may be applied simultaneously to a trainee from multiple directions and multiple planes.
