A portable multi-exercise device includes a pair of parallel tracks each being elongate and linear. The exercise device includes a pair of band attachment platforms positioned across the parallel tracks respectively proximate to ends of the parallel tracks, the band attachment platforms having at least two laterally spaced apart resistance band attachment structures and themselves being laterally positioned along the parallel tracks. Each band attachment platform may include a set of three spaced apart planks defining a slot therebetween in which band fasteners are positioned. The exercise device includes a pair of step platforms atop which a user stands when grasping resistance bands during exercise, the step platforms being laterally adjustable along the parallel tracks. The exercise device includes a rowing bar coupled to the pair of parallel tracks intermediate the band attachment platforms and having fasteners for attachment to the resistance bands.
