If you want the cheapest, simplest way to cover roughly 5 to 50 pounds per hand with a quick dial, the Bowflex SelectTech 552 is the more convenient pick. If you want a compact, squared-off frame with a path to heavier loads, the PowerBlock Elite EXP is the better long-term buy. Both replace a rack of fixed dumbbells, and both involve trade-offs in feel, durability and price that matter more than the headline weights.
This is a specification-based comparison, not a long-term hands-on test. We compared the published weight ranges, increments, warranty terms and owner-facing documentation from both makers, and cross-checked them against third-party reviews. We could not verify a current PowerBlock Elite EXP street price, so we leave exact prices out and tell you to check them.

How We Compared These Dumbbells
We looked at what each manufacturer publishes about weight range, increment size, dimensions and warranty, and compared those claims with independent reviews. We did not load either set for a set number of weeks and we report no personal measurements. Where reviewers disagreed, such as on the PowerBlock's lowest starting weight, we say the sources conflict. Prices change often, so verify current pricing before buying.
Bowflex SelectTech 552 and PowerBlock Elite EXP Side by Side
| Factor | Bowflex SelectTech 552 | PowerBlock Elite EXP |
|---|---|---|
| Weight per hand | 5 to 52.5 lb | 5 to 50 lb, expandable to 70 or 90 lb with add-on kits |
| Increments | 2.5 lb steps in the lower range, 5 lb above | 5 lb steps, with smaller add-on increments sold separately |
| Adjustment method | Dial on each end | Metal pin moved between weight layers |
| Shape | Round plates in a tray | Squared frame, you grip a handle inside it |
| Price | Lower on the street (verify current pricing) | Often higher, more with expansion kits (verify current pricing) |
| Warranty | Check the maker's current terms | One source lists five years, verify the current terms |
Weight Range and Why Increments Matter
A set that jumps in 5 pound steps asks a lot of a shoulder press at light weights. The Bowflex 552's smaller 2.5 pound steps in the lower range make progressive loading smoother for lateral raises and curls. The PowerBlock's 5 pound jumps are coarser, although add-on increments exist. Our progressive overload explainer covers why small steps matter, and why jumping too fast is a common way to get hurt.
Range is the other half. The Bowflex tops out at 52.5 pounds per hand, which many lifters outgrow on rows and presses. The PowerBlock can be expanded to 70 or 90 pounds per hand with extra kits, at extra cost. If you expect to get strong, the PowerBlock's ceiling is a real advantage, and the Bowflex is the one to buy if you do not.
How the Two Designs Feel to Use
The Bowflex dial is fast. Turn it, lift, and the unused plates stay in the cradle. Reviewers describe the round plates as bulkier at the ends, which can bump your forearms or wrists on some moves, and some note plastic components in the cradle and connectors. We cannot verify those durability points ourselves, so weigh them as owner and reviewer reports.
The PowerBlock's squared frame has a compact footprint and reviewers describe a solid steel construction. The trade is a pin change instead of a dial, which is slower between sets, and a handle inside a frame that can feel unusual on moves like dumbbell flyes. Some lifters prefer it for presses because the weight sits close to the hand.
Space, Storage and Home Gym Fit
Both save floor space compared with a full dumbbell rack. The Bowflex cradle is wider, while the PowerBlock frame is narrower per hand. If you are building a small training area, our home gym setup guide and best home gym equipment pillar cover how dumbbells fit around a bench and floor space. Measure your space before buying, since both sets are heavy to move.
Safety and Technique Notes
Adjustable dumbbells add one new risk, which is a plate or pin not fully engaged. Check the selector position every set, and stop if anything shifts. Warm up before heavy sets, which our warm-up guide explains, and see our injury avoidance guide for technique basics. If you have an injury, a heart condition, or you are new to lifting after a long break, talk to your doctor or a qualified trainer before choosing a starting weight. We are reviewers, not clinicians or coaches.
Dumbbells Compared With Other Ways to Train
Dumbbells are one option among several. Our free weights versus machines comparison covers the trade-offs, and Tonal versus free weights compares a smart machine. Neither set is a full gym, and if you plan to bench or squat heavy you will eventually want a rack and bar.
Which One We Would Buy
For a beginner or someone who wants a fast dial for circuits, the Bowflex 552 is the practical first set. For a lifter who already trains and expects to outgrow 50 pounds, the PowerBlock Elite EXP and its expansion path make more sense despite the higher cost. Check the warranty, return window and current price at the seller before you decide.
Price, Warranty and Buying Checklist
The Bowflex 552 has appeared at sale prices well below its list price in 2026 deal roundups, while we found no reliable current price for the PowerBlock Elite EXP, so compare both at checkout and include shipping and any expansion kits. Ask about the return window, because dumbbells are heavy and costly to send back. Confirm the warranty length and what it covers, since a mechanism that wears out is the likeliest failure on either set.
A short checklist helps. Measure your storage spot, decide whether you expect to press or row above 50 pounds, and think about how often you change weights mid-workout. Fast circuits favor the dial, heavy straight sets favor the frame. Buying used can save money, but inspect the dial or pins and the plates for wear.
The bottom line: buy the Bowflex SelectTech 552 for a fast, affordable first set, and choose the PowerBlock Elite EXP if you expect to lift past 50 pounds per hand.
