10 Best Adjustable Dumbbells 2025 in the United States

The BowFlex SelectTech 552 Adjustable Dumbbells are a versatile and space-efficient option for those looking to replace multiple sets of dumbbells. With a weight range of 5 to 52.5 pounds and 2.5-pound increments up to 25 pounds, they cater to a wide variety of exercises, from light curls to heavy lunges. The dial adjustment mechanism is user-friendly, allowing quick and easy weight changes, which is a significant advantage over traditional dumbbells that require manual plate changes.

This feature saves both time and space, as it eliminates the need for 15 different sets of dumbbells, making it an excellent choice for home gyms with limited space. The build quality, using alloy steel and a thermoplastic rubber handle, ensures durability and a comfortable grip during workouts. However, the dumbbells are relatively bulky, and adjusting the weight might require some practice to become entirely smooth.

Additionally, at 105 pounds total item weight, they can be cumbersome to move around. Despite this, the included 2-month free JRNY membership for strength-training and bodyweight workouts adds value to this product. The BowFlex SelectTech 552 is particularly suitable for users looking for a comprehensive, compact, and adjustable weight system for varied fitness routines.

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 LifePro Adjustable Dumbbells Set is a solid choice for anyone looking to enhance their home workout routine without sacrificing space. With a weight range of 5 to 25 lbs and an easy slider mechanism for quick adjustments, these dumbbells cater well to users who need versatility in their training. Their compact design makes them ideal for smaller living spaces, allowing you to easily store them after workouts.

One of the notable strengths of this set is the enhanced durability, featuring a non-slip grip and robust safety locks that ensure secure handling during exercises. This is particularly important for users who may be new to weight training and require assurance during their workouts. Additionally, the included storage rack helps keep your workout area organized, giving it a tidy look.

While they are great for beginners and intermediate users, more advanced lifters might find the maximum weight limit of 25 lbs per dumbbell limiting for certain exercises. If you're looking to build significant strength, you may need to invest in heavier weights down the line. Furthermore, the handle dimensions could be a concern for those with larger hands, as the 1-inch diameter may not provide the same comfort under heavier loads.
