Which has more weight capacity, Bowflex or PowerBlock?

Out of the box, Bowflex's 52.5 lb per hand edges out PowerBlock's 50 lb Stage 1 ceiling. But PowerBlock's staged expansion kits take the same dumbbells to 70 lb (Stage 2) and 90 lb (Stage 3), giving it a much higher long-term ceiling than the Bowflex 552, which has no official expansion path at all.

Which takes up less space, Bowflex or PowerBlock?

PowerBlock's block-shaped, stacked-plate design stays consistently narrower handle-to-handle than the Bowflex 552's round-plate dial design, especially as weight increases. For floor pressing or a tight apartment training space, PowerBlock has a real practical advantage.

Is the dial or the pin easier to use?

Both are fast, roughly 3 to 5 seconds per dumbbell. The dial's single continuous turn is slightly more intuitive for first-time users, while the pin requires pushing it fully into the slot, which a small number of new users initially seat only partway. Both become equally fast with a few sessions of practice.

Is PowerBlock's expansion path actually cheaper than buying the Bowflex upfront?

Not necessarily. Stage 1 alone costs roughly the same as the Bowflex 552. Adding Stage 2 and Stage 3 kits later brings the total cost above what a single higher-ceiling purchase would have cost upfront. The expansion path is valuable for spreading cost over time and for buyers genuinely uncertain about their future weight needs, not for saving money overall if you already know you'll need the higher weight.

Which brand has better long-term parts availability?

Bowflex, by a meaningful margin, reflecting its larger install base and longer market presence. Replacement dials, trays, and handle parts are widely available. PowerBlock parts are available directly from the manufacturer but with a smaller aftermarket and fewer third-party sellers.

Bowflex SelectTech 552 vs PowerBlock Elite EXP: Which Should You Buy?

The Bowflex SelectTech 552 (dial, 5-52.5 lb) and PowerBlock Elite EXP (pin, 5-50 lb expandable to 90 lb) are the two most-compared premium adjustable dumbbells. This comparison covers mechanism speed, footprint, expandability, and who should buy each.

Bowflex SelectTech 552 versus PowerBlock Elite EXP is the closest matchup in the adjustable dumbbell category, and both are frequently recommended as the top pick, which makes the actual differences worth spelling out clearly.

The Bowflex brings a dial mechanism, a 52.5 lb per hand ceiling, and by far the largest install base and track record of any adjustable dumbbell. The PowerBlock counters with a pin mechanism, a narrower footprint, and an expansion path that can take the same base unit from 50 lb up to 90 lb per hand over time.

On everyday adjustment speed, testing and owner reports put the two close to even, both landing in the 3 to 5 second range per dumbbell once the user is familiar with the mechanism.

The real dividing line is footprint and future weight needs. Buyers in tight spaces or planning to grow into heavier weight lean PowerBlock; buyers who want the single most proven, widely supported system and don't need more than 52.5 lb per hand lean Bowflex.

The Short Answer

Buy the Bowflex SelectTech 552 if you want the fastest, most proven mechanism, don't expect to need more than 52.5 lb per hand, and value the widest parts and accessory ecosystem.

Buy the PowerBlock Elite EXP if floor space is tight, you want the narrowest handle-to-handle footprint for floor pressing, or you want a clear path to grow past 50 lb per hand later without buying a new set.

Spec Comparison

Spec	Bowflex SelectTech 552	PowerBlock Elite EXP
Weight range	5 to 52.5 lb per hand	5 to 50 lb (Stage 1), expandable to 90 lb
Mechanism	Dial	Pin
Increment	2.5 lb throughout	Base increments plus 2.5 lb micro-adders
Footprint	Wider, round-plate design	Narrower, block-shaped design
Expansion path	None	Stage 2 (70 lb) and Stage 3 (90 lb) kits
Price	$429 to $449	Approx. $379 (Stage 1)

Where They Match

Adjustment speed: Both land in the 3 to 5 second range per dumbbell, a negligible real-world difference.

Build quality: Both feel solid and well-constructed, with steel internals in each case rather than lower-cost plastic mechanisms.

Included storage: Both ship with a tray or stand that also functions as the weight-change station.

Where Bowflex Wins

Install base and track record: Bowflex has the largest user base and longest history in the category, translating to wider parts availability and more established resale value.

Consistent increments: 2.5 lb steps across the full range give more even progression than PowerBlock's base increments alone.

Where PowerBlock Wins

Footprint: The block-shaped design stays narrower at every weight setting, a genuine advantage for tight training spaces and floor pressing.

Growth path: Stage 2 and Stage 3 kits let you expand to 90 lb per hand without buying an entirely new set, valuable for lifters whose strength trajectory is still uncertain.

Who Should Buy Each

Bowflex SelectTech 552: buyers who want the most proven mechanism, a ceiling around 50 lb per hand is enough, and space isn't a hard constraint.

PowerBlock Elite EXP: buyers in small apartments or shared spaces, or anyone who wants room to grow into heavier weight without a second purchase.
