The method includes performing a body exercise without weights using an elastic cord, a stability ball, and/or a stretch cord with an apparatus having a ground-engaging base plate which rigidly supports first and second vertical members, where each vertical member has aligned clearance openings. Holding members are attached to the base plate for removably holding stretch cords and a support bar is removably received by two aligned clearance openings in the first and second vertical members.
