1. A method of exercising the abdominal and oblique muscles using a weight structure from the group comprising dumbbells, barbells, kettleballs, or weight plates, consisting essentially of the steps
(a) positioning the user on a declined support surface and moving said weight structure relatively toward the user's hips when said abdominal and oblique muscles are extended; (b) contracting said abdominal muscles concentrically by raising the user's head; (c) moving said weight structure relatively toward the user's head when said abdominal and oblique muscles are contracted; (d) extending said abdominal muscles eccentrically by lowering the user's head.
