Abstract
A pull-up fitness exercise machine with a grip bar hanging frame structure for a hang-up training includes a support board. The support board is automatically lifted upward by a pushing unit for the user to take an expected pull-up exercise. The pushing unit is activated by an electric adjusting element in a mechanism box unit for a proper adjustment of the pushing force. The support board is provided with a hand-operated switch unit and a foot-operated switch unit for cooperating with their corresponding barbed hooks respectively, such that the support board can always be kept at a relatively low position in the case that the foot-operated switch group is not stressed. A hanging frame having a plurality of corresponding hanging bars is positioned on both top ends of the front frame for providing a random hanging of a grip bar with a safety sling.
