Overview
This is a dumbbell listed by GYMENIST under model FBA_4051165, sold within Amazon's Dumbbells category for home and gym strength training. The listing does not break out a specific weight, material or grip style, so buyers should confirm those details on the product page before ordering.
The model number carries an FBA prefix, which is an Amazon fulfillment label rather than a manufacturer part number, so it does not tell you the actual weight or finish of the dumbbell. What stands out is the review base: 1,400 ratings at a 4.8 average is a large sample for a single dumbbell listing, though the data does not show which weight variants those reviews cover.
- Brand: GYMENIST
- Category: Dumbbells
- 4.8 average across 1,400 ratings
- 50 bought in the past month
Who it's for
Suited to buyers who already know which weight and grip style they want and are comparing GYMENIST specifically, rather than someone browsing on specs alone. Anyone who needs an exact poundage confirmed before purchase should check the variant selector on the listing itself.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large review base at a 4.8 average
- Steady recent purchase volume
- No weight, material or grip spec listed
- Model number is an Amazon fulfillment code, not a descriptive part number
Performance notes
With no material, weight or dimension data available, the clearest signal here is the review record: 1,400 ratings averaging 4.8, and 50 units bought in the past month. That volume suggests steady ongoing demand, but it does not substitute for a stated weight or handle diameter.
