Generic Adjustable Hand Grip Strengthener

The product shown is a common adjustable hand grip strengthener, typically used for forearm and finger strength training. This specific model features an adjustable tension dial (calibrated from 10kg to 100kg) and a digital or mechanical counter at the base to track repetitions. These devices are generally unbranded 'white label' products manufactured by various factories in China and sold globally under numerous private-label brands on platforms like Amazon, AliExpress, and local sports retailers.

Because the image does not display a visible brand logo, it is classified as a generic fitness tool. The design incorporates a high-quality spring and ergonomic plastic handles with a rubberized grip. Originating as a specialized tool for rock climbers and physical therapy patients, these grip trainers have become mainstream fitness accessories due to their affordability and portability. Manufacturing is almost exclusively concentrated in industrial hubs in China, distributed by various export companies.
