We found the Flybird Adjustable Dumbbells to be the best value — they were more budget-friendly than others and offered plenty of safety features. During lifting, the buckle structure on the weight plates locks the plates so they don't fall off. The safety lock design also ensures the weights can only be adjusted while sitting on the provided tray.

The noncircular shape is also appealing to our experts. Sergii Putsov, CPT, PhD, and head of Sport Science at Torokhtiy Weightlifting, says this is ideal because they won't roll away if you're placing them on the ground between sets, and the design works well for push-ups and floor circuits, thanks to their stability.

Gregor Parella, CPT, CSCS and fitness consultant for Ringside 24, also prefers this brand due to the 5-pound increment adjustments available up to 25 pounds and the fact they come with storage trays.

Of course, it's important to note that these dumbbells top out at 25 pounds, which may not be ideal if you're working on building strength with the goal of lifting heavier weights. The brand offers a 55-lb adjustable dumbbell for roughly $350, but the weight increases at 10-pound increments (15, 25, 35, 45 and 55 pounds), which may not offer the versatility you need, particularly when performing exercises that require less weight.
