An exercise apparatus with two legs attached to opposite lateral sides of a front part of a base so as to be swingable away from and toward the base in a horizontal plane, the legs being adjustable relative to the base, is provided. A head member is mounted on an upper end of a telescoping shaft of a support column pivotally mounted to the front part of the base and a pair of arms is mounted on opposite sides of the head member so as to be pivotable about a horizontal axis, and about an axis perpendicular to the horizontal axis, and securable at various positions so as to change an angle defined by the arms. A separate exercise unit is mounted to a free end of each arm so that the exercise unit can be rotated about a longitudinal axis of the arm and secured in desired positions.
