Bowflex SelectTech 552 vs PowerBlock Elite: Best Adjustable Dumbbell in 2026?

If you searched “Bowflex 552” on Amazon in 2026, you already know the story: the original SelectTech 552 — one of the best-selling adjustable dumbbells of the past two decades — was recalled by the CPSC on June 5, 2025. Nearly 3.84 million units were pulled after 337 reports of weight plates separating from the handle during use, including 111 injuries ranging from broken toes to concussions.

The replacement, the BowFlex Results Series 552, arrived with reinforced metal locking tabs addressing the mechanical failure. It’s now the model worth evaluating — not the recalled original.

That context matters for this comparison. If you’re choosing between the Bowflex Results Series 552 and the PowerBlock Elite EXP in 2026, you’re picking between two genuinely strong options at the same price point (~$399), with fundamentally different approaches to adjustability. One prioritizes speed and ergonomics. The other prioritizes compactness and future expandability.

Quick Comparison

The Products

BowFlex Results Series 552 SelectTech

The Results Series 552 is what the SelectTech 552 should have been. The dial selector — still the fastest weight-change mechanism available on any adjustable dumbbell — now pairs with reinforced metal locking tabs designed to prevent the plate separation that caused the 2025 recall. The plastic selector discs of the original model have been replaced with entirely metal components on updated production runs.

Practically: you turn the dial to your desired weight, lift the dumbbell out of the tray, and the selected plates lock into position. The full range runs 5 to 52.5 lbs per dumbbell. In the lower range (5–25 lbs), increments drop to 2.5 lbs, which matters for isolation exercises and progressive overload — the difference between 12.5 and 15 lbs is significant for lateral raises and curls.

The ovalized handle is the ergonomic win most reviewers overlook. The Bowflex grip mimics a traditional dumbbell more closely than the PowerBlock’s rectangular housing, which changes how the weight sits in your hand during pressing, curling, and hinging movements. Based on owner reports, users coming from traditional dumbbells adapt to the Bowflex handle immediately; the PowerBlock takes a few sessions to feel natural.

The limitation is non-expandability. The 52.5 lb ceiling is permanent. For most home gym users doing dumbbell presses, rows, curls, and lateral raises, 52.5 lbs covers everything. For someone building serious strength who expects to eventually need 70–90 lb dumbbells for rows or Romanian deadlifts, the PowerBlock’s expandability changes the math.

The recall history is worth addressing directly: if you’re buying new from Amazon, you’re getting the Results Series — not the recalled model. If you’re buying used or inherited a set, verify it’s the Results Series before using it.

PowerBlock Elite EXP (Stage 1)

The PowerBlock Elite EXP is the most compact adjustable dumbbell in its weight class. At 12.5 inches long, it’s meaningfully shorter than the Bowflex’s 15.8 inches at the same weight setting. For small home gyms, apartment setups, or anyone storing dumbbells under a bench or in a corner, that 3-inch difference in length is real.

The adjustment mechanism is a magnetic selector pin. Slide the pin into the corresponding slot on the weight selector, and the plates below that setting lock onto the handle when you lift. The system is reliable and mechanically simple — fewer moving parts than the Bowflex dial, no plastic components in the locking path. Based on owner reports spanning years of daily use, PowerBlock Elite EXP pairs rarely rattle or develop selector issues.

The expandability is the standout feature for serious lifters. Stage 1 covers 5–50 lbs at ~$399. A Stage 2 expansion kit brings you to 70 lbs per hand; Stage 3 extends to 90 lbs. If you start at Stage 1 and grow into the weight range over 18–24 months of consistent training, your initial investment scales with you rather than forcing a full replacement.

Two practical downsides surface consistently in owner feedback. First, the pin selector is slower than the Bowflex dial. Changing from 20 lbs to 40 lbs requires pulling the pin, repositioning it, and confirming the lock — a 10–15 second process versus the Bowflex’s 3-second turn. For circuit training or supersets where you’re changing weights frequently, this adds up. Second, the manual lock lever must be engaged before each lift. The Elite EXP requires you to slide the lever closed; it doesn’t auto-lock. Missing this step is a safety issue — the weights will come loose.

The knurled steel handle is a genuine advantage for pulling movements. The texture provides grip security under load that the Bowflex’s smooth ergonomic handle can’t match during heavy rows or RDLs.

Dial vs Pin: Which Adjustment System Is Right for You?

This is the core decision point.

Choose the dial (Bowflex Results Series 552) if:

• You change weights frequently during workouts — supersets, circuits, or high-rep isolation work
• You prioritize an ergonomic grip that feels like a traditional dumbbell
• Your training tops out under 52.5 lbs per hand
• Ease of use matters more than long-term expandability

Choose the pin (PowerBlock Elite EXP) if:

• You want to grow into heavier weights over time without buying a new set
• Space is at a premium — the compact design stores in tighter spots
• You value mechanical simplicity and proven long-term durability
• You’ll eventually need 70–90 lbs for serious compound lifting

Buying Guide: What to Look for in Adjustable Dumbbells

Weight range and increments. The 2.5 lb jump between 5–25 lbs is significant for shoulder work and arm training. Both options here cover this. Beyond 50 lbs, only the PowerBlock can grow with you.

Footprint. Adjustable dumbbells need a tray or rack. Factor in floor or shelf space: the Bowflex pair with trays takes 33 x 8.5 inches; the PowerBlock pair is more compact. If you’re using a dumbbell rack or shelf, measure first.

Adjustment speed. If your training involves supersets or frequent weight changes, the Bowflex dial is meaningfully faster. If you work in straight sets with rest between, the PowerBlock pin is adequate.

Durability. Both carry 5-year warranties. The PowerBlock’s welded steel construction has a longer track record. The Bowflex Results Series is newer, but the addition of metal locking tabs addresses the specific failure mode that caused the recall.

Future-proofing. Beginners and intermediate lifters should consider whether their strength will outpace their equipment in 12–24 months. The PowerBlock expandability option is real value if you’re still progressing.

FAQ

Is the Bowflex 552 safe to buy in 2026 after the recall? Yes, if you’re buying new. The recalled product was the original SelectTech 552 (CPSC recall date: June 5, 2025). Current Amazon listings are for the BowFlex Results Series 552, which features reinforced metal locking tabs and an updated selector design. If you own a pre-recall pair, stop using it and contact Bowflex at recall@bowflex.com or 800-209-3539 for a refund or replacement.

What’s the difference between PowerBlock Sport EXP and Elite EXP? The Sport EXP has an auto-lock feature (the lever engages automatically when you insert the handle), while the Elite EXP requires a manual lock. The Sport also has a more modern appearance with powder-coated steel and no support bars at the top of the handle, which some users with larger hands prefer. Both expand to 90 lbs with Stage kits. Pricing is similar.

Can PowerBlock Elite EXP really go to 90 lbs? Yes, but not out of the box. Stage 1 covers 5–50 lbs ($399). The Stage 2 kit adds 55–70 lbs; Stage 3 adds 75–90 lbs. Each kit is a separate purchase. If you want 90 lb capacity from day one, the full bundle costs significantly more than either option covered here.

Do these dumbbells work on a dumbbell rack? Both work on standard A-frame and flat dumbbell racks. The PowerBlock’s compact square design fits standard rack slots. The Bowflex sits in its included cradles — you’d want to keep the cradles on any rack you use.

Which is better for beginners? The Bowflex Results Series 552. The dial is faster, the ergonomic grip is more intuitive, and the 2.5 lb lower-range increments support careful progression during the beginner phase. The PowerBlock’s expandability only matters if your training outgrows 52.5 lbs, which takes most beginners 12–24 months of consistent training.

Conclusion

Both options land at the same price point and represent the two legitimate approaches to adjustable dumbbells at this tier.

The BowFlex Results Series 552 wins on user experience. The dial is genuinely faster than any pin-based system, the ergonomic handle feels like a traditional dumbbell, and the 52.5 lb range covers the full scope of dumbbell training for most people. The Results Series addresses the 2025 recall issues directly with metal reinforcement. If you want the most practical, easy-to-use adjustable dumbbell under $400, this is it.

The PowerBlock Elite EXP wins on long-term value. The compact design stores easier, the welded steel construction has a longer durability track record, and the expandability to 90 lbs protects your investment if your strength progresses beyond the 50 lb range. Serious lifters who expect to be pressing and rowing heavy within a year should pay attention to that ceiling.

The tie-breaker for most buyers: if you’re primarily doing upper-body isolation, circuits, and moderate-weight compound work, get the Bowflex. If you’re building a serious strength base and expect to need heavier weights in the next two years, get the PowerBlock.
