Overview

An adjustable grip strengthener (GD GRIP ULTRA-70) with resistance from 55 to 154 pounds (25 to 70 kg) and handle width adjustable from 45 to 85mm, giving 17 resistance combinations.

The parallel-grip handle design is the mechanical detail that sets this apart from spring-loaded grippers: force applies evenly across all four fingers rather than concentrating on one or two, and the maker states the resistance rating reflects actual hand grip strength rather than an inflated spec number common on cheaper grippers.

  • Adjustable 55-154 lbs (25-70 kg)
  • 17 resistance and width combinations
  • Parallel four-link handle structure
  • Patent protected design

Who it's for

Suited to lifters and grip-sport athletes who want a wide, adjustable resistance range for both warm-up and negative training in one tool. Less useful for a casual user who only wants a light, fixed-resistance gripper for occasional use.

Pros and cons

Pros
  • Adjustable resistance from 55 to 154 lbs
  • Handle width adjusts from 45 to 85mm
  • Parallel-grip design distributes force evenly

Performance notes

The four-link parallel handle structure keeps grip distance and force even across all fingers as you close the handles, building strength through the whole hand and forearm rather than just the strongest fingers. Resistance and handle width both adjust independently, giving 17 combinations from a single unit.
