A portable modular exercise apparatus for multiple users is separable into multiple components by pin connections. The modularity of the versatile exercise device enables numerous types of exercises by multiple users simultaneously. The apparatus comprises two upright support towers, a base with base pads under each support tower, an overhead crossbeam and a supplemental sliding push up cross bar, a number of resistance bands which attach to the apparatus for the purpose of resistance training, and a carrying bag to contain and transport all of the components. Pin connections allow the device to easily be assembled and taken apart without tools.
