Abstract: An adjustable exercise apparatus is an apparatus that engages both halves of an antagonist muscle group during the extension and retraction of specific movements and exercises. The apparatus includes a base frame, a first track, a second track, a crossbar, a first resistance-piston system, a second resistance-piston system, a first lockable mount, and a second lockable mount. The base frame stabilizes the upright orientation of both the first track and the second track along the ground. The crossbar reinforces the position and the orientation of the first track and the second track with each other. The first resistance-piston system and the second resistance-piston system provides an adjustable resistance to a variety of movements and exercises throughout use. The first lockable mount and the second lockable mount secures the desired position of the first resistance-piston system and the second resistance-piston system along the first track and the second track, respectively.
