A resistance apparatus includes a track adapted to be secured in a vertical position on a support. A vertical slide is mounted and slideable and has on the track a spring loaded plunger near a first end thereof. A hook is mounted on the slide and has a pair of spaced apart legs, with upper and lower end portions, with the lower end portions of the legs connected by an upwardly extending U-shape portion. The upper end portion of the second leg has a downwardly extending curved portion which is laterally spaced from the upper end portion of the first leg to form therewith an entrance opening into the interior of the hook. A resistance band has an intermediate portion which is received in the interior of the hook through the entrance opening to permit a person to grasp the ends of the resistance band and to perform various resistance exercises.
