Overview
An adjustable hand gripper with a resistance range from about 11 to 350 pounds (5 to 160kg), set via a spring or knob, with a mechanical counter that logs reps automatically.
Rather than buying a set of fixed-resistance grippers, this tool covers a wide range in one unit, adjustable at the front knob to fit different palm sizes as well. The listing also frames it for hand therapy and post-surgery recovery, not just strength training, on the basis that resistance can be dialed down to light levels.
- Adjustable resistance about 11-350lbs (5-160kg)
- Mechanical auto rep counter
- Manganese steel spring, ABS shell
- Compact 5.2 x 6.2 x 2 inch size
Who it's for
Fits someone who wants one gripper spanning beginner through advanced resistance, or who needs adjustable light resistance for hand or wrist rehab rather than a single fixed-strength tool.
Strengths and trade-offs
Drawn from this product's published specifications.
- Wide adjustable resistance range in a single tool
- Automatic mechanical rep counter
- Compact enough for a bag or desk drawer
- Grip width adjusts for different hand sizes
- No buyer reviews yet to confirm the resistance range or spring durability
- Comfort under sweat depends on the rubber grip texture, which is unverified by reviews
Performance notes
Resistance is set by turning a knob or repositioning a spring, changing effort from light rehab levels up toward 350 pounds. A mechanical rep counter tracks each squeeze automatically, and the front knob also adjusts grip width for different hand sizes.
