EXTEND YOUR PLATE LOADED MACHINE WITH GYMPIN MACHINE EXTENDERS
BUILT FOR BIGGER LOADS ON COMPATIBLE HAMMER STRENGTH PLATE LOADED EQUIPMENT
GymPin Internal Machine Extenders are designed to give compatible Hammer Strength plate loaded machines more usable loading space, allowing serious lifters to add more Olympic weight plates when the standard machine weight horn has run out of room.
Simply slide the extender inside the existing machine bar to create a longer loading sleeve. Each extender adds over 6 inches / 152mm of extra loading space per side, helping you push heavier on compatible leg presses, rows, chest presses, shoulder presses and other plate loaded equipment.
Sold as a pair, these UK designed and manufactured extenders are built from high-quality materials for demanding gym environments, strength athletes, bodybuilders, powerlifters and commercial facilities that need practical extra loading capacity without replacing the machine.

Product Information
GymPin Internal Machine Extenders are designed to add extra loading space to compatible plate loaded gym machines when the standard weight horns are no longer enough.
They slide inside the existing machine weight horns to create a longer usable loading bar, giving you more room to add Olympic weight plates during heavy strength training.
Each extender adds over 6 inches / 152mm of extra loading length per side, making them ideal for heavy leg presses, chest presses, rows, shoulder presses and other compatible plate loaded movements.
Sold as a pair, the extenders allow lifters to keep using their existing equipment while increasing plate loading capacity.
These extenders are built for serious lifters, commercial gyms, strength facilities and anyone using compatible plate loaded gym equipment where the built-in loading horns limit progression.
They are especially useful for bodybuilders, powerlifters and strength athletes who regularly max out the available loading space on machines.
If you are loading serious weight onto compatible Hammer Strength-style plate loaded equipment and running out of room before you run out of strength, these are made for you.
Standard machine loading horns can become a limiting factor for stronger lifters.
Once the horn is full, progression stops. Not because the athlete cannot lift more, but because the machine physically cannot take any more plates. A thrilling design flaw, because apparently gravity needed admin.
GymPin Internal Machine Extenders solve that problem by increasing usable loading space without changing the machine itself.
Designed and manufactured in the UK, they give serious lifters a simple, heavy-duty way to keep progressing on compatible plate loaded equipment.
These internal machine extenders are designed to fit compatible Hammer Strength plate loaded equipment.
They are not universal machine extenders, so please check your machine dimensions carefully before ordering.

Cybex-specific extenders can also be made. If you need extenders to fit Cybex equipment, please enter “Extenders to fit Cybex equipment” in the notes when placing your order.
Always check machine compatibility and dimensions before ordering or using the extenders.
Only use the extenders with suitable plate loaded gym equipment and ensure they are fully inserted and secure before loading plates.
Load plates evenly on both sides of the machine and do not exceed the safe operating limits of your equipment.
These extenders are designed to increase loading space, not override poor machine setup, damaged equipment, or reckless loading. Sadly, metal is strong but not magic.

Cybex-specific extenders can also be made.
If you need extenders to fit Cybex equipment, please enter “Extenders to fit Cybex equipment” in the notes when placing your order.
Each extender adds over 6 inches / 152mm of extra usable loading length per side.

BUILT FOR HEAVY PLATE LOADED TRAINING
Progressive overload does not stop being important just because your machine has run out of loading space. Sadly, the machine does not care about your goals. Rude, but predictable.
For stronger lifters, plate loaded gym machines can eventually become the bottleneck. The movement still works, the machine still feels right, but the standard loading horns simply do not give you enough room to keep adding plates.
GymPin Internal Machine Extenders solve that problem.
Designed for compatible Hammer Strength plate loaded equipment, they slide inside the existing machine weight horns to create a longer loading bar. Each pair gives you over 6 inches / 152mm of extra usable loading length per side, allowing more 2" Olympic weight plates to be added for heavy strength training.
They are ideal for serious leg presses, chest presses, rows, shoulder presses and other plate loaded machine exercises where measurable progression matters.
More loading room. More room to progress. Less arguing with a machine that clearly wasn’t built with your final set in mind.
