ABSTRACT:
A portable pull-up apparatus may include a plurality of hollow support poles and a plurality of pulley wheel sections. A pull-up bar may further be horizontally placed on top of the support poles. Weights may further be situated within an interior of the support poles. A plurality of cables provided with handles adapted to be gripped by a user may be wrapped about the pulley wheel sections such that the distal ends of the cables are guided inside the support poles respectively. A plurality of selector rods may be through the weight groups. A plurality of anchor pins may be positioned to lock selected weights. Further resistance bands may be situated within the interior of the support poles. In this way, corresponding resistance band groups may cooperate with corresponding weight groups to create a unique tension force opposing vertical displacement of the distal end of the cables respectively.
