said workout device further configured to accept at least one module configured to be grabbed by said vice-like mechanism and further configured to accept additional modules sequentially, such that after the insertion of said at least one module, another module may be added, followed by further additional modules, with a maximum number of modules being limited by the space between said fixed jaw and said movable jaw;

wherein the non-circular cross section of said threaded rod is defined by two opposite cylindrical threaded sides and two opposite flat sides, wherein a width of the threaded rod measured between the two opposite flat sides is smaller than a width of the threaded rod measured between the two opposite cylindrical threaded sides;

wherein said slider joint is formed by said non-circular cross section of said threaded rod passing through and being received by an opening in said fixed jaw;

wherein an axis of said slider joint defines an axial direction of said vice-like mechanism and a radius of said threaded rod defines a radial direction of said vice-like mechanism;

wherein said at least one module is configured to:

a) radially slide between said fixed jaw and said movable jaw;

b) be axially gripped between said fixed jaw and said movable jaw;

c) include an axial cylindrical hole, a diameter of said axial cylindrical hole being not smaller than the width of the threaded rod measured between the two opposite cylindrical threaded sides of said threaded rod, allowing said at least one module to freely rotate about and axially slide along the threaded rod when said threaded rod is located completely inside said axial cylindrical hole;

d) include a slot, configured to:

extend from a perimeter of the at least one module to said axial cylindrical hole;

wherein the slot has a width not smaller than the width of the threaded rod measured between said two opposite flat sides, but smaller than the width of the threaded rod measured between the two opposite cylindrical threaded sides of the threaded rod, such that the threaded rod can only be slid into the slot when the two opposite flat sides are in line with the slot, but cannot be slid into the slot if otherwise aligned due to the width of the threaded rod measured between the two opposite cylindrical sides being bigger than the width of the slot;

wherein the slot guides the threaded rod to slide into said axial cylindrical hole, where the threaded rod can freely rotate;

e) have an inserted position when the at least one module is inserted between said fixed jaw and said movable jaw, wherein the threaded rod is completely inside said axial cylindrical hole;

f) have an engaged position where:

the at least one module is in said inserted position;

the two opposite flat sides of the threaded rod are not aligned with said slot and consequently the threaded rod cannot enter the slot, thus, the at least one module is radially locked and cannot radially move away from the threaded rod, while said at least one module can still axially slide along the threaded rod, and rotate about the threaded rod in order to become disengaged from the threaded rod;

g) include at least one axial guiding pin, which protrudes from at least one end of the at least one module; and

h) include at least one receiving opening, wherein the at least one receiving opening is configured to receive at least one axial guiding pin of another module, wherein the another module is separate from the at least one module;

wherein said fixed jaw and said movable jaw each include at least one receiving opening which are separate from said at least one receiving opening of said at least one module, and are configured to receive said at least one axial guiding pin of said at least one module;

said at least one axial guiding pin and said at least one receiving opening of said at least one module are configured to interact with said at least one receiving opening of said fixed jaw and said at least one receiving opening of said movable jaw;

wherein, when said at least one module is positioned in the inserted position, said at least one module must first be axially rotated to misalign said two opposite flat sides of the threaded rod with said slot;

wherein said misalignment prevents the threaded rod from sliding inside the slot, thereby securing said engaged position;

wherein, once in the engaged position, said at least one axial guiding pin of the at least one module can be positioned inside the at least one receiving opening of the fixed jaw, the movable jaw, or another module; and

wherein the another module is separate from the at least one module that is positioned in the engaged position;

said secured modular quick coupling system further characterized by:

radially locking said at least one module when said at least one module is positioned in said engaged position;

locking the rotation of said at least one module around the threaded rod by engaging said at least one axial guiding pin of said at least one module and said at least one receiving opening of said fixed jaw, or said at least one receiving opening of said movable jaw or said at least one receiving opening of another module, wherein the another module is separate from the at least one module, thus, preventing said at least one module from rotation and unwanted disengagement from said threaded rod;

axially locking said at least one module between said fixed jaw and said movable jaw, and consequently preventing said at least one guiding pin of said at least one module from sliding out of said at least one receiving opening of said fixed jaw, or said at least one receiving opening of said movable jaw or said at least one receiving opening of another module, wherein the another module is separate from the at least one module; and

preventing said at least one module from vibrating and jiggling by tightening the vice-like mechanism by rotating said adjustment nut.
