A multi-purpose, adjustable fitness apparatus is provided for performing exercises; in particular, sliding pull-ups and push-ups. Two in-line metal bars are interposed by a T-connector. A sliding handle grip may be disposed on each bar between a pair of retaining collars. A radius elbow including a foot is attached to each bar. A first adapter for a first setting includes a crossbar and elbow tube is slidably locked to the perpendicular leg of the T-connector. The apparatus may be mounted over a doorframe; the elbow tube and T-connector provides adjustability to fit frames of various widths. A second adapter for a second setting includes a third foot fitted to the T-connector, and provides stability on a horizontal surface.
