Add More Weight to Gym Machines with GymPin Cable Stack Extenders

GymPin is a UK-designed strength training brand best known for cable stack extenders, machine extenders and specialist gym accessories that let lifters get more from pin-loaded and plate-loaded machines.

The Original GymPin is a cable stack extender that lets you add 2 inch Olympic weight plates to compatible selectorised or selectorized cable machines when the built-in weight stack is no longer heavy enough.

The right GymPin depends on your machine, selector pin diameter and available clearance. The Original 2 inch GymPin is available in 8 mm and 10 mm versions. Measure your existing selector pin or weight stack hole before ordering.

GymPin products are designed for serious training and are used with compatible home, commercial and professional gym equipment. Compatibility depends on the machine, pin size, weight stack design and clearance around the stack.

The Original GymPin is the main 2 inch cable stack extender for adding Olympic plates to compatible cable machines. The MiniPin is a more compact loading option, while the KingPin is built for heavier specialist setups and is available in 10 mm only.

GymPin Machine Extenders are designed to increase loading space on compatible plate-loaded machines. They help lifters add more Olympic plates to machines such as leg press, hack squat, row, chest press and shoulder press setups where loading sleeve space is limited.

Yes. GymPin products are built around progressive overload: adding more resistance, improving loading options and helping lifters continue progressing when standard machine weight stacks or loading sleeves become limiting.

No. GymPin products are purpose-designed strength training accessories, not generic products with a label added afterwards. Each product is designed around a specific training problem, from adding plates to cable stacks to extending machine loading space.
