I’ll be honest — I resisted buying adjustable dumbbells for years. I always assumed they were gimmicky, overpriced, or would fall apart the moment I pushed them hard. Then my garage started looking like a sporting goods warehouse, and I finally caved. After months of daily use, here’s my unfiltered take on the BowFlex Results Series SelectTech 552 Adjustable Dumbbells.

First Impressions: Out of the Box
When the box arrived, I was not prepared for how dense the packaging was. These things weigh in at 110.6 pounds as a pair — your delivery driver earns every penny on this one. Once unpacked, though, the build immediately communicated quality. The plastic and rubber construction feels more premium than I expected for a dial-based system, and the metal internal components give the dumbbell a reassuring solidity when you pick it up.
The storage trays that come included are a thoughtful touch. They keep the plates neatly aligned when the dumbbells are docked, which also protects the locking mechanism between sessions.
The Dial Adjustment System: Genuinely Clever Engineering
The headline feature here is the quick-adjust dial system, and after months of use, I can say it genuinely delivers. Rotating the dial moves you through weight increments from 5 to 52.5 pounds per dumbbell — that’s 15 individual weight settings in one compact unit. What used to take 90 seconds of swapping iron plates now takes about three seconds.
For anyone who does drop sets, supersets, or circuit training, this is a genuine quality-of-life upgrade. One reviewer on Amazon, a self-described 20-year gym rat, called these “the best on the market,” and I understand exactly where that’s coming from. The mechanism produces an audible click and a satisfying tactile snap when a weight setting locks in, so you always know the plates are secure before you lift.
One adjustment worth noting: when returning the dumbbell to its tray, you need to line up the discs with the slots in the base.
It’s not difficult, but it does require a moment of attention — something Cassandra, a verified buyer, summed up perfectly: “you do have to engage a brain cell.” Fair warning for anyone who likes to move quickly between sets.
Build Quality and the Post-Recall Context
The product currently shipping is the redesigned Results Series, which introduces reinforced metal selector disks and an upgraded locking system specifically to address the issues that prompted that recall.
From my hands-on experience, the improvements are tangible. The plates do not shift during dynamic movements like curls, presses, or lunges. The locking mechanism holds firm throughout my workouts, including some heavier compound lifts. That said, I want to be transparent: one negative reviewer (Frank Carlson, verified purchase, January 2026) reported persistent rattling and inconsistent docking with his set. His experience was in the minority among the reviews I’ve read, but it’s worth acknowledging — quality control on any manufactured product can vary unit to unit, and if your set feels off out of the box, the return process through Amazon is straightforward.
David Boggs, another buyer, noted a slight dip in quality compared to older BowFlex generations and felt the brand name carried a premium he wasn’t fully getting. I haven’t owned previous versions, so I can’t make that direct comparison — but for a first-time buyer, the current version feels well-built for the price point.
Handle, Grip, and Ergonomics
The non-slip rubber grip is comfortable for most standard movements — chest presses, shoulder raises, bicep curls, and rows all feel secure. The ergonomic handle is shaped to reduce wrist strain, which I noticed particularly during longer sets.
Where the grip falls slightly short, in my opinion, is during heavy, sweaty sessions. A few users have echoed this — rubber becomes less secure when your palms are wet. One reviewer specifically wished the grip were knurled (textured metal, like what you’d find on a barbell) rather than rubber, and I lean that direction too. It’s a minor nitpick that doesn’t affect everyday performance, but if you train intensely without gloves, it’s something to be aware of.
The dumbbells are also somewhat bulkier than traditional fixed-weight dumbbells, which is the unavoidable trade-off of the adjustable design. For most exercises this doesn’t matter at all, but certain close-range or chest-supported movements can feel slightly awkward.
Valentina, a verified buyer who put together a detailed video review, said the same — she called it “a trade-off I’m happy with,” and that’s about where I land too.
Space Savings: The Real Selling Point
Here’s the number that matters most for home gym owners: these two dumbbells replace 15 separate pairs of weights. If you’ve ever priced out a full dumbbell rack — 5s through 50s in 5-pound increments — you know that setup costs more, takes up significantly more floor space, and adds real complexity to a home workout room.
For anyone living in an apartment, using a spare bedroom, or just trying to keep things minimal, the SelectTech 552s solve a real problem elegantly.
One buyer, Roger, put it simply: “Bowflex is absolutely one of the best products out there for people that have minimum space and want to work out with different weights. After months of use in my own setup, I can’t argue with that.”
Performance Across Different Exercises
I’ve used these for a wide range of movements — flat bench press with a utility bench, overhead shoulder press, Romanian deadlifts, goblet squats, bent-over rows, and various isolation work. The results are consistent across the board: the weights stay locked, the balance is good, and the transition between exercises is fast.
One thing I was pleasantly surprised by was stability during heavier compound work. Dennis Nielsen, a verified buyer, mentioned using the full 52.5-pound setting for both flat and inverted bench presses without issue, which aligns with my experience. These are not toys. They perform like real training equipment because they are real training equipment.
Robert, a 3-star reviewer, pointed out that the size of the dumbbells makes them “wonky” for some lifts, requiring a tighter grip to control wobble. I’ve noticed this mildly during certain movements but found that once you’re past the initial adjustment period, your grip adapts. It’s also worth noting that traditional dumbbells at heavier weights are themselves not perfectly balanced, so this isn’t entirely unique to adjustable designs.
Who These Are Best For
After extensive use, I’d say the BowFlex Results Series SelectTech 552s make the most sense for home gym users who want versatility without the footprint of a full dumbbell rack, intermediate to advanced lifters who regularly train across a broad weight range in a single session, people transitioning from commercial gym memberships who want to replicate that experience at home, and beginners who want room to grow — the 5-pound starting point is accessible, and the ceiling at 52.5 pounds is enough to carry most people through years of progressive strength training.
Any Real Cons?
Being straightforward about it: these are expensive. If your budget is tight, the upfront cost will sting. But when you compare the price against buying a full set of fixed dumbbells — or the convenience cost of a commercial gym membership over a few years — the math shifts considerably in their favor.
The rubber grip, as mentioned, could be better. And the size of the dumbbell housing at lower weight settings means you’re always carrying the full length of the handle regardless of what you’ve selected, which is a limitation inherent to the dial-adjust design.
Finally, if you drop these regularly from any height, don’t expect them to hold up. They’re precision-engineered equipment, not indestructible cast iron. Dennis Nielsen’s point about not dropping them is worth repeating — treat them accordingly and they’ll last a long time.
Final Verdict
The BowFlex Results Series SelectTech 552 Adjustable Dumbbells earn their reputation. The engineering is smart, the space savings are real, the weight range covers everything a home lifter needs, and the post-recall redesign addresses the safety concerns that plagued earlier versions. For anyone serious about building or expanding a home gym, these are among the most practical investments you can make.
Would I buy them again? Without hesitation.
Where to Buy
Purchase only from Amazon’s official storefront to ensure you’re receiving the authentic Results Series version with proper warranty coverage. One user on Amazon who bought a knockoff adjustable dumbbell from an off-brand seller nearly dropped a plate on his foot mid-workout — the BowFlex version solved that problem entirely.
