An apparatus used for cardiovascular workouts and strength training workouts contains a treadmill, a first weight-engaging pulley mechanism, a second weight-engaging pulley mechanism, a first guide channel, and a second guide channel. The treadmill is used to complete the cardiovascular workouts. The first weight-engaging pulley mechanism and the second weight-engaging pulley mechanism are used for strength training. Since the weight arrangement of the apparatus is movable along the first guide channel and the second guide channel, the user can complete a wide variety of strength training workouts. The apparatus also contains an incline-adjustment mechanism, which orients the treadmill belt track to simulate an incline or a decline. A belt direction-reversing mechanism of the apparatus helps change the direction a belt that is layered along the treadmill belt track.
