Abstract: An exercise device including a first platform with an upper wall and side walls. Connector assemblies are engaged with each side wall and are selectively movable therealong. A first end of each resistance band is selectively engageable with one of the connector assemblies. A user positioned on the upper wall engages the second end of each resistance band to perform resisted arm curls. A harness worn on the user's torso is engaged with second ends of the resistance bands and rollers on the harness engage a vertical surface when performing squats. The exercise device includes a second platform that pivots relative to the first platform and is locked in position to present the vertical surface for the rollers. A third platform is pivotally engaged with the second platform and is positionable to present a chin-up bar. Resistance bands engage connector assemblies on the third platform for performing pull-down type exercises.
