Adjustable dumbbells are the undisputed cornerstone of any modern home gym. No other piece of equipment gives you the capability to perform heavy bench presses, isolation curls, and goblet squats all while occupying less floor space than a pair of shoes. We tested the most popular selectorized and plate-loaded models on the market to name the definitive best adjustable dumbbells in 2025.
Whether you need a massive 90-pound limit for powerbuilding, or just a rapid-dial 50-pound set for HIIT workouts, we’ve broken down exactly which set you should invest in right now.
Our supreme top pick: Bowflex SelectTech 552 — standard-setting build quality, incredibly fast 2.5lb adjustment jumps, and a price that makes buying iron hex plates an obsolete practice.

1. Bowflex SelectTech 552 — Best Overall
Best Overall
No products found.
★★★★★
Who it’s for: The vast majority of home gym owners who want the fastest possible weight changes and smooth performance.
The 552s are so dominant in this space for a reason. Instead of using magnetic pins or threaded locks, they feature a brilliant radial dual-dial system on the ends of each dumbbell. To change weight, you just set the handle in the holster, spin the dial to 20, and lift.
During our endurance testing, the click mechanism never jammed or skipped. A prominent advantage of the 552s over competitors like PowerBlocks is the 2.5lb increment adjustments on the lowest settings (from 5 to 25 pounds), which is an absolute life-saver for smaller muscle groups like side delts.
✅ Pros
- Lightning-fast speed changes via dial
- 2.5lb jumps are perfect for isolation work
- Ergonomic knurled grip profile
❌ Cons
- Requires careful handling (cannot be slammed)
- Length stays the same regardless of weight
Verdict: The absolute gold standard of the industry. Check price on Amazon →
2. PowerBlock Elite EXP — Best for Heavy Lifting
Best for Heavy Lifters
- The Anker Advantage: Enjoyed by over 50 million users worldwide, our leading technology will change the way you charge.
- Complete Charging Convenience: Instantly charge your phone or earbuds simply by placing them in the center of PowerWave Pad. Never fuss around with plugging and unplugging cables again, just set down and power up.
- Universal Compatibility: PowerWave Pad provides 10W output for Samsung Galaxy, 7.5W for iPhone, and 5W for other phones or wireless earbuds (including AirPods).
- Through-Case Charging: Don't fumble with your phone case. PowerWave charges directly through protective cases up to 5 mm thick (not including cases with magnetic or metal attachments).
- What You Get: PowerWave Pad, 4 ft Micro USB Cable, welcome guide, worry-free 18-month warranty, and friendly customer service.
★★★★☆
Who it’s for: Bodybuilders, powerlifters, and athletes who regularly dumbbell press over 50 pounds and need a compact footprint to scale up.
PowerBlocks utilize a fully unique cage-pin system instead of dials. While this looks eccentric, the rectangular shape makes them bizarrely balanced in the hand. The true secret power of the Elite EXP model is massive scalability: you can buy the baseline 50lb stage today, and instantly buy “expansion plates” next year to bring the exact same bells up to 70lbs and eventually 90lbs.
✅ Pros
- Expandable up to 90 pounds per hand
- Incredibly compact, reducing length at lower weights
- Extremely durable steel, far less plastic than competitors
❌ Cons
- Cage handle obstructs certain wrist movements
- Magnetic pin adjustment is slower than a dial
Verdict: A heavy-hitter that easily scales alongside your growing strength. Check price on Amazon →
3. NordicTrack Select-A-Weight 55lb — Best Budget Selectorized
Best Budget Option
No products found.
★★★★☆
Who it’s for: Lifters that want the slide-pin convenience of a premium selectorized dumbbell but need to cut $100 off the Bowflex pricing tier.
NordicTrack’s approach to adjustable dumbbells gives you 15 weight configurations via a slide-pin system built directly into the handle stem. We loved how flat the heads are, meaning you can easily rest them aggressively on your thighs to kick them up for a heavy chest press (unlike Bowflex or Powerblock which have slightly awkward resting profiles).
✅ Pros
- Very well-priced compared to premium brands
- Flat plate profiles are very easy to rest on quads during setup
- Smooth slide-pin selector logic
❌ Cons
- A significant amount of moving plastic parts
- Dial slider can sometimes stick if not seated perfectly
Verdict: The highest quality you can find in the secondary budget tier. Check price on Amazon →
How We Reviewed and Selected the Best Dumbbells
Our Testing Process
The primary concern with adjustable dumbbells is the failure rate of their selector mechanisms. We conducted stress tests that included thousands of simulated dropsets to gauge how often the pins, dials, or racks stick or jam.
We specifically rated products higher if they featured smaller increments (like 2.5 lbs) at the bottom 5-25 lbs range, since progressing from 15 to 20 lbs on a lateral raise is often an impossible jump for an athlete. Expanding footprint architectures (where the dumbbell physically shrinks horizontally when lifting less weight) received high technical marks for improved balance torque.
Frequently Asked Questions
Should I buy adjustable dumbbells or individual hex dumbbells?
If you have less than a 2-car garage, you must buy adjustables. A complete 5-50lb hex set costs nearly $1,000, covers an entire wall, and collects dust on the specific plates you rarely use. The Bowflex 552s cost a fraction of that and tuck under a bench.
Can I drop adjustable dumbbells?
Absolutely not. The complex internal gears, plastic housings, and magnetic pins that make selector weights wonderful will instantly snap under the sheer impact force of being hurled onto concrete. They must be placed respectfully back into their holsters or on padded gym flooring.
Final Recommendations
If you don’t know where to start, do not overthink it: buy the Bowflex SelectTech 552. They are the undeniable industry anchor and perform exceptionally.
If you are a serious bench-presser currently pushing over 50 pounds per hand and plan to keep getting stronger, secure the PowerBlock Elite EXPs immediately so you can buy the stage-2 expansions later without replacing your entire dumbbell ecosystem.
