10 Best Adjustable Dumbbells 2025 in the United States

The FEIERDUN Adjustable Dumbbells offer a versatile option for home workouts, with each dumbbell adjustable from 6 to 22.5 pounds. This weight range suits beginners or those looking for light to moderate resistance but may not meet the needs of advanced lifters needing heavier weights. The adjustable design allows for quick changes in weight, and the set includes a connector to use the dumbbells as a barbell, kettlebell, or even push-up stands, which adds value for varied fitness routines.

Build quality combines alloy steel handles with plastic components, and the dumbbell bars have a non-slip ABS surface that helps maintain grip during exercise. The included 20mm thick foam on the connector rod adds comfort and prevents slipping, making it easier on your hands and neck during workouts. Safety nuts securely lock the weights to avoid shaking or accidental slips while lifting.

In terms of size and storage, the set is compact enough for home use, but the plastic parts might not feel as durable as full metal sets over time. The foam grip and non-slip texture enhance comfort, though if you sweat heavily, the foam might wear faster. The set weighs a total of 45 pounds, so it’s manageable for most users but may require some space to store properly. This adjustable dumbbell set is well-suited for people starting out or those wanting a multi-use home gym tool without investing in multiple pieces of equipment. It’s especially useful if you value comfort and safety features during workouts. Serious lifters looking for higher weight options or fully metal construction might want to consider alternatives.

The UNNMIIY adjustable dumbbell set offers a versatile solution for home workouts by combining dumbbells, barbells, kettlebells, and push-up stands in one package. This 45-pound pair allows you to adjust weights from 2 to 22.5 pounds per dumbbell using detachable plates made from a mix of iron, mud, and sand, which helps protect your floors. Its adjustment mechanism involves locking nuts that are thickened for safety, reducing any wobbling during exercises. The dumbbell bars have a non-slip ABS surface and a thick foam grip designed for comfort and better control even when your hands get sweaty.

The set’s build quality feels solid thanks to the mix of durable materials and thoughtful design features like deep grip grooves and a curved connecting rod that fits the neck for kettlebell use. Size-wise, it takes up less than 2 square feet of space, which is convenient for home storage. This weight range might feel limiting for advanced lifters who want heavier options, and the locking nut system, while secure, may be slower to adjust compared to dial mechanisms found on some other models.

For those new to adjustable dumbbells or looking for a multifunctional, space-saving set for varied workouts at moderate weight levels, the UNNMIIY provides great value and safety with reliable comfort.

The NordicTrack 55 lb Select-a-Weight Dumbbell Pair is a versatile solution for anyone looking to save space while maintaining a wide range of weight options for their workouts. With 15 weight increments per dumbbell, it effectively replaces 30 individual dumbbells, offering a compact and efficient alternative for home gyms. The weight can be adjusted in small increments of 2.5 or 5 pounds, making it highly customizable to different fitness levels and training needs.

The included fitted storage trays help keep everything organized and clearly labeled, contributing to a tidy workout space. Constructed from steel and hardened plastic, these dumbbells are built to last, though the use of plastic components may raise concerns about long-term durability for some users. The grip is designed for comfort, but the 4.5-inch handle length and 1.25-inch diameter may feel a bit bulky for those with smaller hands.

Despite their weight and size, these dumbbells are relatively compact, measuring 11.4 inches long by 19.4 inches wide. Additional perks include a free trial of trainer-led workouts via the iFit app, which can enhance the exercise experience. On the downside, the adjustment mechanism, while smooth, may take some getting used to, and the price point might be on the higher side compared to traditional dumbbells. However, the space-saving design and versatility make it a solid investment for those serious about home fitness. The product has received positive reviews, averaging 4.6 out of 5 stars from over 2,000 ratings, suggesting general satisfaction among users.
