Best adjustable dumbbells
Bow Flex Select Tech 552 Adjustable Dumbbells
The BowFlex dumbbells quickly became a fan favorite during the pandemic, and after finally getting a set, I understand why. They arrived well-packed and were easy to set up compared to others I’ve tried. The dumbbells were securely fastened to the rack with straps, and sliding them out onto the floor was effortless.
Featuring a sleek black and red design, these round dumbbells are made from steel, nylon, ABS plastic, and thermoplastic rubber. They replace 15 sets of weights, ranging from 5 to 52.5 pounds. Each dumbbell has two dials, one on each side, which you twist to adjust the weight. While it seems odd to adjust both dials separately, the design ensures a smooth, snag-free experience.
Core Adjustable Dumbbells
After the BowFlex, the Core adjustable dumbbells impressed me with their packaging. The rack was placed at the top of the box, making it easy to access without lifting the heavy weights first. I appreciated the magnetic weight plates, which can be separated before placing the dumbbell on the rack.
These were also the only dumbbells with a loose handle that latched onto both the base and the weight plates. Core’s dumbbells range from 5 to 50 pounds, with weight adjustments in 5-pound increments. They’re simple to use just twist the handle to change the weight, and offer the fastest transition among manual adjustable dumbbells.
Fly bird 55 LB Adjustable Dumbbells
The Flybird 55 LB adjustable dumbbells feature cast iron weight plates and a black plastic-coated handle. They range from 11 to 55 pounds, with adjustments in 11-pound increments. I prefer 5-pound increments, as doubling the weight felt like a significant jump. The dial is simple to use, requiring just a twist to lock in the desired weight. However, unlike other adjustable dumbbells I tested, these don’t allow for in-between weight options.
MX55 Rapid Change Adjustable Dumbbells
The MX55 adjustable dumbbells were quick to assemble, though the hexagonal plate shape took a moment to figure out. Each plate has indented slots to keep them aligned in the rack. The rack arrives pre-assembled, but users must attach protective rubber feet (included in the packaging) to the cradles. These dumbbells replace 10 sets of weights, ranging from 10 to 55 pounds.
Ativafit 71.5 Adjustable Dumbbell Set
The Ativafit 71.5 adjustable dumbbells were my runner-up in several categories, but they proved to be the easiest to use. Ranging from 5 to 71.5 pounds, they replace 12 sets of dumbbells. The plastic rack features grooves that latch onto the dumbbells, keeping them secure when not in use. With sturdy iron plates and a nonslip rubber handle, these dumbbells exude quality and provide a solid grip when increasing weight.
The standout feature is how simple it is to adjust the weights—just press the red button on top and twist the dial. These are the heaviest adjustable dumbbells on the list, making them ideal for serious lifters or anyone new to adjustable weights.
