Weight lifting machine with electromagnetic couplers

A weight lifting machine comprising:

• a stack of weights, each of said weights having an opening, said openings being aligned to define a transverse passage through said stack of weights;
• a pair of guides, each of said weights being slidably mounted on said pair of guides and being movable along said pair of guides from a rest position to an elevated position;
• a selector member, said selector member having a downwardly depending member, said downwardly depending member supporting a plurality of couplers therein, said downwardly depending member having a transverse passage facing side, each of said couplers comprising an electromagnetic coupler having a transverse passage facing side, each of said electromagnetic couplers being positioned in said downwardly depending member such that said transverse passage facing side of said electromagnetic couplers are positioned in said transverse passage facing side of said downwardly depending member whereby each of said electromagnetic couplers has a single exposed side, and each of said electromagnetic couplers being adapted to be selectively energized or de-energized for magnetically coupling said single exposed side to or decoupling said single exposed side from a respective weight in said stack of weights;
• and
• one of a lift cable and a lift bar coupled to said selector member, said one of a lift cable and a lift bar being adapted to permit a user of said weight lifting machine to raise said weights coupled to said selector member from its respective rest position to its respective elevated position.
