The invention is directed to an adaptor for converting a conventional office chair into a multifunctional office/fitness chair. The adaptor comprises a seat connector, a pair of rowing shafts, a seat post holder, and a foldable footrest. By adjusting the angle of the backrest up to 120°, a user can use the converted chair either as a conventional office chair, or as a fitness chair capable of assisting the user to do sit-up exercises in a rowing motion which focuses the exercise forces on the abdominal muscles, burns abdomen fat pad, and therefore effectively reduces waist line. Further, because the rowing motion is assisted by the backrest and armrest, the risk to injure the neck or back is eliminated.
