Key Features & Specifications
Resistance Range: Typically adjustable from 5 kg to 60 kg (or up to 100 kg on heavy-duty models) using a rotary tension dial.
Built-in Rep Counter: Features a 2-digit or mechanical click counter (often counting up to 99) that automatically records each full squeeze. It includes a manual reset knob or button to clear the count between sets.
Material & Build: Usually built with a reinforced alloy steel tension spring and an impact-resistant ABS plastic core.
Ergonomic Handles: Covered with textured, non-slip TPR rubber grips for a comfortable hold that minimizes hand fatigue.
Portable & Battery-Free: Lightweight (around 175g) and operates completely mechanically without needing batteries or external power.
Progressive Strength Training: Allows beginners to start at a low resistance (e.g., 5 kg) and gradually dial it up as grip strength improves.
No Mental Counting: The mechanical counter tracks reps automatically, letting you focus entirely on your form and squeeze intensity.
Rehabilitation & Stress Relief: Frequently used for physical therapy, post-injury wrist or hand recovery, blood circulation, and relieving daily hand tension.
Versatile Use: Suitable for athletes, rock climbers, weightlifters, musicians, office workers, and older adults looking to maintain hand dexterity
