1. A versatile doorway exercise system using a pull-up bar while adding assistance or resistance, wherein said system comprises:
a. a door frame having a vertical first jamb and a vertical second jamb disposed opposed to and parallel with the first jamb, wherein the first jamb comprises a first jamb anterior end and a first jamb posterior end, wherein the second jamb comprises a second jamb anterior end and a second jamb posterior end; b. a linear cylindrical bar having a bar first end and a bar second end, wherein the bar first end is perpendicularly disposed on the first jamb proximal to the first jamb anterior end, wherein the bar second end is perpendicularly disposed on the second jamb proximal to the second jamb anterior end; c. a linear first vertical post having a first post anterior end, a first post posterior end, a first post inside surface, and a first outside surface, wherein the first vertical post comprises a rectangular cross-section in a transverse plane, wherein the first vertical post is disposed on the first jamb, wherein the first post inside surface is parallel to and interfaces with the first jamb, wherein the first vertical post comprises a plurality of rings disposed thereon, wherein the plurality of first rings are incrementally spaced between the first post anterior end and the first post posterior end; d. a linear second vertical post having a second post anterior end, a second post posterior end, a second post inside surface, and a second post outside surface, wherein the second vertical post comprises a rectangular cross-section in a transverse plane, wherein the second vertical post is disposed on the second jamb, wherein the second post inside surface is parallel to and interfaces with the second jamb, wherein the second vertical post comprises a plurality of second rings disposed thereon, wherein the plurality of second rings are incrementally spaced between the second post anterior end and the second post posterior end; and e. a padded resistance member having a plurality of first end elastic bands extending from a resistance member first end and a plurality of second end elastic bands extending from a resistance member second end, wherein each one of the plurality of first end elastic bands comprises a first hook member, wherein each one of the plurality of second end elastic bands comprises a second hook member, wherein at least one first hook member is removably disposed on one of the plurality of first rings, and wherein at least one second hook member is removably disposed on one of the plurality of second rings;
wherein a location of the first ring is chose for attachment based on a desired position of the resistance member for a user relative to a distance between the resistance member and the cylindrical bar or a floor, wherein a location of the second ring is chosen based on the desired position of the resistance member for the user relative to the distance between the resistance member and the cylindrical bar or the floor;wherein additional first hook members are attached to or disattached from the selected first ring to increase or decrease resistance or assistance for the user, wherein additional second hook members are attached or disattached from the selected second ring to increase or decrease resistance or assistance for the user;wherein the user bends at a pair of knees while placing the resistance member on a top surface of each calf behind the knees while placing a pair of hands on the cylindrical bar for use for a pull-up exercise with resistance;wherein the user bends the knees while placing the resistance member on the front surface of the knees while placing the hands on the cylindrical bar for use for a pull-up exercise with assistance;wherein the user stands with a pair of feet on the floor and bends the knees while placing the resistance member on a top surface of a pair of shoulders for use for a squat exercise with resistance. |
