Best Adjustable Dumbbells 2026: 5 Compared
WriterPickly Editorial
Updated 2026-11-03
Adjustable dumbbells swap a rack of fixed weights for one pair, but the way they adjust differs a lot: sliding plates and threading collars, turning a handle, or twisting a dial. Top weight, pair or single, and the price gap matter as much as the brand.
Quick answer
The Amazon Basics 38 lb plate set is the cheapest at $49.49 on Amazon US on November 3, 2026, and the CAP Barbell pair goes much heavier at $125.18. The Amazon Basics dial model is a single dumbbell at $66.14. For quick dial changes in a pair, the Bowflex Results Series 552 is $399.99 and the NordicTrack 55 lb is $399.00.
📋How we compared
We did not lift these dumbbells ourselves. Judging grip, balance and how smoothly each mechanism changes weight needs real workouts, which we cannot run. This comparison is built from the product titles and feature lists on the Amazon US listings, retrieved through the Amazon Creators API on November 3, 2026, and general knowledge of how adjustable dumbbells work. Weights, increments and what is included are the sellers' own claims. Prices move often, so check the retailer.
💰 Cheapest way in: The Amazon Basics 38 lb set is the lowest-priced option here: two 3 lb handles, four 2.5 lb plates, four 5 lb plates and four 0.5 lb collars. You slide plates on and secure them with threaded collars, and a black storage case with a carry handle is included.

How the weight changes
Three mechanisms appear here. The Amazon Basics 38 lb set and the CAP Barbell pair are plate-loaded: you slide plates on and secure them with collars, which the CAP listing calls star-lock collars. The Amazon Basics dial model changes weight by turning the handle in 5 lb steps. The Bowflex listing mentions quick adjustment dials and the NordicTrack listing a weight selector. Plate-loading takes longer between exercises but costs less, while dial and selector designs change weight faster for a higher price.
Top weight, pair or single
The Amazon Basics 38 lb listing is a set of two with 38 lb in total, about 19 lb each if split evenly. The CAP listing is a pair totalling 105 lb, up to 52.5 lb per dumbbell. The Bowflex covers 5 to 52.5 lb per dumbbell and the NordicTrack is listed at 55 lb per dumbbell. The Amazon Basics dial model is a single dumbbell topping out at 25 lb, so a pair means buying two.
Handles, storage and price
The CAP listing describes 17-inch knurled chrome handles, longer than the compact handles on the dial models. The Bowflex and NordicTrack listings both include storage trays, and the Amazon Basics 38 lb set comes with a carry case. The two big dial pairs cost roughly eight times the Amazon Basics plate set, so think about how often you will change weight before paying for speed.
