A permanently affixed and travelling selector pin, car and weight plate selection mechanism for use with physical fitness equipment is disclosed including a segmented track and/or cut out cavern within the plate body for the car to travel within in either vertically or horizontally in order to select a different weight plate or cumulatively, more or less weight for an exercise. The selector pin and car mechanism features a selector pin which is not removable from the car and is inserted through the car which is contained by the track and or plate body shape and into a throughbore in the weight plate in order to engage with the selector stem.

The assembly defined in claim 1, wherein each weight plate of the plurality of weight plates is of unitary construction. 3. The assembly defined in claim 1, wherein the weight stack is oriented in a horizontal stack such that, when engaged, the selector pin retains one or more of the plurality of weight plates for exercise that are disposed on the first side of the selected weight plate. 4. The assembly defined in claim 1, wherein the lower catches and the upper catches of the plurality of weight plates are cooperatively formed such that each lower catch can lift the adjacent upper catch. 5. The assembly defined in claim 1, wherein the lower catches and the upper catches of the plurality of weight plates are cooperatively formed to inhibit lateral movement between adjacent weight plates. 6. The assembly defined in claim 5, wherein the lower catches and the upper catches of the plurality of weight plates are cooperatively angled in a V-shape configuration to inhibit lateral movement between adjacent weight plates. 7. The assembly defined in claim 1, wherein the movement arm includes a four-bar linkage configured to maintain the selector stem in a fixed orientation relative to the ground throughout a range of operation, while displacing one or more of the weight plates for exercise. 8. The assembly defined in claim 7, wherein the movement arm includes two bars aligned parallel to each other throughout the range of operation. 9. The assembly defined in claim 7, wherein the weight stack is oriented in a horizontal stack such that, when engaged, the selector pin retains one or more of the plurality of weight plates for exercise that are disposed on the first side of the selected weight plate. 10. A weight lifting assembly, comprising: a weight stack comprising a plurality of weight plates in an aligned arrangement, each weight plate having first side that defines a lower catch, a second side that defines an upper catch, and a peripheral edge therebetween, the plurality of weight plates are aligned such that the lower catch and the upper catch of adjacent weight plates cooperatively align with each other; each weight plate of the plurality of weight plates defining a u-shaped stem cavity disposed in an intermediate region of the plate, each stem cavity of the plurality of weight plates are aligned with each other, the weight stack having: a plurality of engagement points corresponding to the plurality of weight plates, anda track defined by the weight stack for guiding between the plurality of engagement points;a selector stem that extends through the stem cavities of the plurality of weigh plates to retain one or more of the plurality of weight plates for exercise via the plurality of engagement points; anda selector pin having a knob and an elongated axial shaft extending therefrom, the shaft including a distal end, the pin includes a retaining portion disposed between the knob and the distal end on the shaft;wherein the axial shaft of the selector pin is sized to achieve union between the selector pin, the selected weight plate, and the selector stem, in an engaged position, thereby retaining one or more of the plurality of weight plates for exercise that are disposed on the first side of the selected weight plate, and, in a disengaged position, the retaining portion is captured within the track so as to preclude the removal of the selector pin, wherein further, in the disengaged position, the retaining portion of the selector pin is confined by the track such that the selector pin can travel along the track to enable selection of a weight plate of the plurality of weight plates. 11. The assembly defined in claim 10, wherein the weight stack in oriented in a horizontal stack such that, when engaged, the selector pin retaining one or more of the plurality of weight plates for exercise that are disposed on the first side of the selected weight plate. 12. The assembly defined in claim 10, further comprising a movement arm pivotally coupled to the selector stem to displace one or more of the weight plates for exercise. 13. The assembly defined in claim 12, wherein the movement arm includes a four-bar linkage configured to maintain the selector stem in a fixed orientation relative to the ground throughout a range of operation, while displacing one or more of the weight plates for exercise. 14.
