Overview
Not a soft foam grip ball, this is a V-shaped alloy steel trainer with an adjustable spring tension. The title lists forearm and wrist training as its purpose.
A broad resistance range is the reason to consider it, since the same unit can serve a beginner and a strong user. The limitation is the sparse listing, with no handle material, adjustment details or counter described.
Who it's for
Strength athletes and people building forearm strength can step up the tension over time. Beginners with weak or injured hands should start with a lighter resistance and ask a professional first.
Pros and cons
- Wide adjustable resistance range
- Alloy steel body
- Compact V shape
- High tension rating
- Adjustment method not described
- Handle padding not described
- Contents of the box unclear
Performance notes
The trainer resists the squeezing force with a spring, and the adjustment sets how hard each squeeze is. Controlled repetitions through the full range build forearm and grip strength. Resistance feels higher at the top of the squeeze.
