The plate loaded weight lifting equipment are different compared to selectorized gym equipment in the sense that they use individual plates for resistance. The plate loaded gym equipment is preferred by many athletes because it allows them almost unlimited loading of weight resistance as an user can load many plates on each side of the machine. Metagenics Fitness offers several lines of plate-loaded equipment for strength training. The only negative aspect is that it takes more time to load plates in a piece of gym equipment than to select a specific weight with a selector pin.
