Abstract:
1. A portable pull-up apparatus for assisting a user to perform pull-up exercises between a framed opening, said portable pull-up apparatus comprising: a plurality of hollow support poles spaced apart and registered parallel to each other; a plurality of pulley wheel sections attached to top ends of said support poles respectively; a pull-up bar horizontally placed on top of said support poles and adapted to be frictionally engaged within the framed opening such that said pull-up bar is registered perpendicular to said support poles; first and second groups of weights situated within an interior of said support poles respectively; a plurality of cables each having a proximal end situated exterior of said support poles and provided with a handle adapted to be gripped by the user, said cables being wrapped about said pulley wheel sections such that distal ends of said cables are guided inside said support poles respectively; a plurality of selector rods attached to distal ends of said cables and being positioned through said first and second weight groups respectively; a plurality of anchor pins positioned through said selector rods respectively and thereby locking selected weights of said first and second weight groups to said selector rod; and first and second groups of resistance bands anchored to said first and second weight groups respectively; wherein corresponding ones of said first and second resistance band groups cooperate with corresponding ones of said first and second weight groups and thereby create a unique tension force opposing vertical displacement of said distal end of said cables respectively.
