The best adjustable dumbbells (2026)

REP’s QuickDraw page lists pairs at 30, 40, 50 and 60 lb, starting at 5 lb, with Lock-N-Load steel switches and two 2.5 lb micro-adjustment plates. A 60 lb pair can replace 12 fixed pairs, according to REP, and the handle is a 32 mm fully knurled volcano-style grip. REP says the switches were cycle tested more than 100,000 times, the bells were drop tested, and the set carries a lifetime warranty that does not cover consistent drops, accidents or normal wear. BarBend named the QuickDraw its most durable adjustable dumbbell, with prices starting at $335.99, and its testers called the click-in switches among the fastest they have used. The 60 lb ceiling is the limit; if you already press more than that, look at an expandable cage design or a loadable handle instead.

Bowflex’s Results Series 552 SelectTech page lists a pair at $399 on sale, $479 regular, with a promotion noted through November 14, 2026 at 11:59 p.m. CT when we fetched the page. Each bell runs 5 to 52.5 lb across 15 settings (2.5 lb steps up to 25 lb, then 5 lb steps), and Bowflex says one pair replaces 15 sets of weights. The official dimensions are 16.9" × 8.3" × 9" per dumbbell. Adjustment is a twist-dial, the grip is a non-slip (not knurled) handle, trays are included, and the listed parts warranty is two years. BarBend named the Results Series 552 its beginner pick at $479 and was still testing the new version as of its August 21, 2026 update, after a June 5, 2025 recall of older Bowflex 552 and 1090 models. If you already own a recalled set, use the recall process BarBend points to rather than buying a second older unit.

The Pro 100 EXP is PowerBlock’s expandable residential set: a 5–40 lb pair is $539, then official stage prices are $758 (60 lb), $977 (80 lb) and $1,196 (100 lb), in knurled or TPR grips. PowerBlock lists a 5–100 lb range with 2.5 or 5 lb micro weights, a magnetic selector pin, urethane-coated plates, 19.21" × 7.63" × 7.72" dimensions at max expansion, a 38 mm grip (32 mm knurled grips sold separately), and a five-year limited residential warranty. One pair replaces 30 traditional pairs and about 1.75 feet of floor, per the official FAQ, versus a 7-foot rack. BarBend named the Pro 100 EXP its pick for small spaces, starting at $539, and scored durability lower than all-metal sets because of some plastic parts, so this is not a set to bounce off the floor. It is also a square, open-handle “block” shape, not a round dumbbell. If 50 lb is clearly enough, the non-expandable Pro 50 is a closer price and size match for the 552; we cover that head-to-head separately.
