wherein the first threaded cylindrical portion is threadingly engaged with a threaded recess on one of the head plate and bayonet and wherein the second threaded cylindrical portion axially extends from the threaded recess, oppositely with respect to the bayonet;

wherein the second threaded cylindrical portion is threadingly engaged with a jam nut;

wherein an operator can visually determine when the elongated connector is not fully engaged with the threaded recess when the first threaded cylindrical portion is not fully disposed in the threaded recess; and

wherein an operator can visually determine when the elongated connector is fully engaged with the threaded recess when the first threaded cylindrical portion is fully disposed in the threaded recess.

2. The exercise equipment according to claim 1 , wherein the bayonet has a first end that extends into the head plate and a second end that extends into the weight stack and wherein the threaded recess is formed in the first end of the bayonet.

3. The exercise equipment according to claim 1 , wherein the monolithic elongated stud has a through-bore that axially extends through the first threaded cylindrical portion and the second threaded cylindrical portion, and wherein the cable extends completely through the through-bore.

4. The exercise equipment according to claim 3 , wherein the cable has a free end that is sized larger than a diameter of the through-bore along the first threaded cylindrical portion such that the free end engages with the first threaded cylindrical portion and cannot pass through the through-bore.

5. The exercise equipment according to claim 4 , wherein the free end is hall-shaped.

6. The exercise equipment according to claim 1 , wherein the jam nut has an inner diameter that is smaller than the outer diameter of the first threaded cylindrical portion such that the jam nut cannot threadingly engage with the first threaded cylindrical portion.

7. The exercise equipment according to claim 6 , further comprising a locking washer that is sandwiched between the jam nut and the threaded recess, wherein the cable extends through the locking washer.

8. The exercise equipment according to claim 1 , further comprising a stop collar that is disposed on the elongated connector, wherein the stop collar comprises at least one locking screw that is engaged with the elongated connector when the elongated connector is fully engaged with the threaded recess.

9. The exercise equipment according to claim 1 , wherein the first threaded cylindrical portion comprises at least one flat surface that is configured for engagement with a tool for manually rotating the elongated connector.

10. A method of assembling exercise equipment, the method comprising:

providing a weight stack having a plurality of weights that are configured to oppose a given exercise motion through a cable and pulley system;

providing a head plate disposed on the weight stack;

providing a bayonet extending from the head plate into the weight stack;

connecting the cable and pulley system to the head plate and bayonet via a removable elongated connector;

wherein the removable elongated connector comprises a monolithic elongated stud having a first threaded cylindrical portion and a second threaded cylindrical portion that axially extends from the first threaded cylindrical portion, wherein the first threaded cylindrical portion has an outer diameter that is greater than an outer diameter of the second threaded cylindrical portion;

threadingly engaging the first threaded cylindrical portion with a threaded recess on one of the head plate and bayonet such that the second threaded cylindrical portion axially extends from the threaded recess, oppositely with respect to the bayonet;

threadingly engaging the second threaded cylindrical portion with a jam nut;

visually determining when the removable elongated connector is not fully engaged with the threaded recess when the first threaded cylindrical portion is not fully disposed in the threaded recess; and

visually determining when the removable elongated connector is fully engaged with the threaded recess when the first threaded cylindrical portion is fully disposed in the threaded recess.

11. The method according to claim 10 , wherein the jam nut has an inner diameter that is smaller than the outer diameter of the first threaded cylindrical portion such that the jam nut cannot threadingly engage with the first threaded cylindrical portion.

12. The method according to claim 11 , further comprising sandwiching a locking washer between the jam nut and the head plate, wherein the cable extends through the locking washer.

13. The method according to claim 10 , further comprising disposing a stop collar on the removable elongated connector, wherein the stop collar comprises at least one locking screw that is engaged with the removable elongated connector when the removable elongated connector is fully engaged with the threaded recess.

14. The method according to claim 10 , wherein the first threaded cylindrical portion comprises at least one flat surface, and the method further comprising manually engaging the at least one flat surface with a tool and manually rotating the removable elongated connector until the first threaded cylindrical portion is fully disposed in the threaded recess.

15. Exercise equipment comprising:

a weight stack having a plurality of weights that are configured to oppose a given exercise motion through a cable and pulley system;

a head plate that is disposed on the weight stack;

a bayonet that extends from the head plate into the weight stack;

and an elongated connector that removably connects the cable and pulley system to the head plate and bayonet;

wherein the elongated connector comprises a monolithic elongated stud having a first threaded cylindrical portion and a second threaded cylindrical portion that axially extends from the first threaded cylindrical portion, wherein the first threaded cylindrical portion has an outer diameter that is greater than an outer diameter of the second threaded cylindrical portion;

wherein the first threaded cylindrical portion is threadingly engaged with a threaded recess on one of the head plate and bayonet and wherein the second threaded cylindrical portion axially extends from the threaded recess, oppositely with respect to the bayonet;

wherein the second threaded cylindrical portion is threadingly engaged with a jam nut;

wherein an operator can visually determine when the elongated connector is not fully engaged with the threaded recess when the first threaded cylindrical portion is not fully disposed in the threaded recess;

wherein an operator can visually determine when the elongated connector is fully engaged with the threaded recess when the first threaded cylindrical portion is fully disposed in the threaded recess;

wherein the monolithic elongated stud has a through-bore that axially extends through the first threaded cylindrical portion and the second threaded cylindrical portion, and wherein the cable extends completely through the through-bore; and

wherein the cable has a free end that is sized larger than a diameter of the through-bore along the first threaded cylindrical portion such that the free end engages with the first threaded cylindrical portion and cannot pass through the through-bore.
