Overview
The FITPLAM adjustable dumbbell set is a pair of plate-loaded dumbbells that adjust across 20, 35, 45, 55, 70, and 90 pound settings, built from alloy steel, iron, and polyethylene with an upgraded locking nut.
Adjustable dumbbells like this exist to replace a full rack of fixed weights with two units that cover a wide range, which matters most for home gyms short on space. The upgraded nut is FITPLAM's answer to the loose spinlock collars found on cheaper adjustable sets, though changing between all six settings still means threading plates rather than the instant swap of a dial system. With 4,000 units bought last month and a 4.3 rating across 1,424 reviews, demand looks strong even if the rating trails some premium dial-adjustable competitors.
- Adjusts across 20/35/45/55/70/90 lb settings
- Upgraded locking nut mechanism
- Sold as a pair, 2 pieces
- Black and red color
Who it's for
Fits home gym users who want one pair of dumbbells covering a wide weight range without buying a full rack. Less ideal for anyone who wants the fastest possible weight changes between sets, since this is a nut and plate system rather than a dial.
Strengths and trade-offs
Drawn from this product's published specifications.
- Six weight settings from one pair, 20 to 90 pounds
- Upgraded locking nut over basic spinlock designs
- Strong recent demand, 4,000 bought in the past month
- Slower to adjust than dial-based systems
- 4.3 rating trails premium adjustable dumbbells
- Threaded nut system can still loosen with heavy use
Performance notes
The set works by threading plates onto a bar and locking them with the upgraded nut, which should hold more securely during lifts than a basic spinlock collar, though it is slower to adjust than turn-dial adjustable dumbbells. Alloy steel and iron plates supply the weight, while the polyethylene likely covers grip or plate coating. At a maximum 45 pounds per side in the listed attribute, the pair combines for up to 90 pounds total at the top setting.
