Overview
A rope and handle forearm roller you load with your own weight plates, up to 130 lbs on the load pin. The cord winds and unwinds as you twist the handle, working the forearm flexors and extensors along with grip and shoulder stabilizers.
This is the classic gym-style roller, not one of the newer spring or resistance-band forearm trainers. It works with plates you already own rather than shipping its own weight, so the real cost of a session depends on what you load onto the pin. The load pin fits 25mm or 50mm bore plates.
- Load pin rated to 130 lbs (60 kg)
- Fits 25mm and 50mm bore plates
- Non-slip foam grip handle
- Works in both over and under winding directions
Who it's for
Suits lifters, climbers and combat-sport athletes who already keep weight plates around and want a low-cost way to add forearm and grip work to a routine. Less useful for anyone without spare plates, since none are included.
What buyers say
From Amazon customer reviews.
Buyers say it delivers the classic wrist-roller workout at a low price, with several noting it works well in both winding directions and holds up to daily use. The main complaint is a slightly loose feel in the setup and a handle some found too thin for bigger hands.
