Bowflex SelectTech 552 Review: Still Worth It in 2026?

The Bowflex SelectTech 552 has been the best-selling adjustable dumbbell set for over a decade. Not because Bowflex has the best marketing budget — though they do — but because the core product is genuinely excellent. After 12 months of using this pair five days a week in a real home gym, here is the unfiltered verdict: it is still the one to beat for most lifters, but it is not right for everyone.

How the Dial Mechanism Actually Works

Most reviews gloss over the mechanism and just say "turn the dial." Let me explain what is actually happening inside the cradle because it changes how you use and maintain these dumbbells.

Each SelectTech 552 consists of a central handle surrounded by 15 weight plates stacked in the cradle. The dial on each end of the dumbbell controls a series of interlocking cams and locking tabs. When you rotate the dial to a target weight, those tabs engage at the corresponding plate position. Plates at and below your selected weight lock onto the handle; plates above that weight stay seated in the cradle. When you lift the handle out, only the selected plates come with it.

The mechanical precision here is real. The cams have hard stops at each weight increment — you feel and hear a distinct click. There is no ambiguity about whether you are at 25 lbs or 27.5 lbs. Each number locks in positively.

The weight range runs from 5 lbs to 52.5 lbs in the following increments:

• 5, 7.5, 10 lbs (2.5 lb jumps)
• 12.5, 15, 17.5, 20, 22.5, 25 lbs (2.5 lb jumps)
• 30, 35, 40, 45, 50, 52.5 lbs (5 lb jumps above 25)

The 2.5 lb increments in the lower range are a significant advantage for beginners and for isolation movements where small jumps matter. The switch to 5 lb jumps above 25 lbs is a minor frustration if you are doing overhead pressing or lateral raises in the 30–45 lb range and want intermediate steps.

Real-World Testing: 12 Months of Daily Use

I ran these through a full year of training. Here is what I actually found, exercise by exercise.

Pressing Movements

Flat dumbbell press, incline press, shoulder press — these are where the 552 performs best. The handle diameter (1.3 inches) is comfortable for pressing, and the overall length at lower weights is normal. At 45–52.5 lbs, the dumbbell is noticeably longer than a fixed dumbbell of the same weight — approximately 15.75 inches at max weight. This extra length is not a problem for flat pressing but can feel awkward on incline work if you are bringing them to your shoulders from your knees.

The dial-change speed is where this product earns its reputation. Going from a 40 lb pressing set to a 20 lb fly set takes under 3 seconds. I timed it. For supersets and circuits, that speed is genuinely irreplaceable.

Row and Pull Movements

Single-arm rows, chest-supported rows, bent-over rows — no issues here. The handle grip is secure and the plates do not rattle even under heavy load. I ran several sets of heavy single-arm rows at 52.5 lbs without any sensation of play in the mechanism.

One note: do not let these swing freely during the eccentric on heavy rows. If the dumbbell swings hard at the bottom and the plates briefly unload, the locking tabs can sometimes fail to re-engage properly. Keep tension on the weight throughout the range of motion, same as you would with a fixed dumbbell.

Isolation Movements

Curls, lateral raises, tricep kickbacks — this is where the 2.5 lb increments in the lower range shine. Being able to jump from 15 to 17.5 lbs on a curl without buying a whole new dumbbell is exactly what makes adjustable sets worth having. At the upper end of isolations (lateral raises in the 20–35 lb range), the 5 lb jumps above 25 lbs become limiting. It is the one place I found myself wishing for 2.5 lb plates across the full range.

Floor and Athletic Movements

These are not designed for cleans, snatches, or any movement where the dumbbell leaves your hand and catches air. Do not use them for that. The dial mechanism does not appreciate impact loading. For goblet squats, Romanian deadlifts, and farmer carries — movements where you hold the dumbbell continuously — they work fine, though the wider profile at heavier weights makes goblet squats slightly less comfortable than a fixed kettlebell.

Durability: What 12 Months Looked Like

At 12 months of five-day-a-week training, both dumbbells are mechanically identical to day one. The dials click cleanly, the plates lock with the same precision, and there is zero wobble in the handles. This is not a product that degrades with normal use.

What does cause problems:

1. Dropping. Set them down controlled, every single time. The dial cam system is precision-machined plastic. Impact from a drop — even from 6 inches onto a rubber mat — can crack a cam or dislodge a locking tab. This is the number one reason people have bad experiences with the SelectTech 552.

2. Off-center re-racking. The cradle has alignment guides for a reason. If you drop the dumbbell back into the cradle tilted or at an angle, a plate on one end may not seat correctly. The mechanism will still turn, but you may find yourself carrying an incomplete set of plates. Always re-rack centered and level.

3. Re-racking under load. Some people twist the dial while they are still holding the weight under load. The mechanism is designed to be adjusted in the cradle only. Adjusting under load stresses the cam edges and will shorten the lifespan of the mechanism over time.

The handle rubber does show cosmetic wear after extended use — the texture has smoothed slightly where my palms contact. Functionally irrelevant. I train with chalk occasionally and that helps grip in humid conditions.

Bottom line on durability: treat these like precision equipment, not a barbell, and they will last years. One conversation with a powerlifter friend who has had his pair for seven years with zero issues confirms this.

Bowflex 552 vs. The Competition

This is the comparison most buyers actually need. The adjustable dumbbell market has gotten genuinely competitive. Here is where the 552 sits relative to the alternatives you will actually consider.

Bowflex 552 vs. PowerBlock Elite 50

The PowerBlock Elite 90 family uses a selector pin system with a removable adder weight, and it is the most legitimate competitor to the SelectTech line.

Weight range: PowerBlock Elite 50 goes to 50 lbs; SelectTech 552 goes to 52.5 lbs — essentially equal.

Speed: The Bowflex dial is faster. PowerBlock's pin system requires pulling the pin, repositioning, and re-inserting. Three to four seconds versus two seconds is real when you are doing high-rep circuits.

Durability under abuse: PowerBlock wins here. The metal selector pin system is more forgiving of rough handling than the Bowflex cam system. If you train in a garage where things get knocked around, or if you have kids, the PowerBlock is the safer long-term bet.

Size: PowerBlock is more compact at equivalent weights. The stacking design keeps the length nearly constant across all weights, whereas the Bowflex gets longer as you add plates.

Feel: This is subjective, but the Bowflex feels more like a traditional dumbbell. The PowerBlock's open-cage design and side-entry grip are different enough from a fixed dumbbell that some lifters never get comfortable with it.

Verdict: Bowflex for speed and feel. PowerBlock for durability and compactness. If you train hard five days a week and handle your equipment carefully, Bowflex. If you share your gym with others or train in an environment where things get dropped, PowerBlock.

Bowflex 552 vs. NUOBELL 50

The NUOBELL 50 uses a rotating collar system that makes it look and feel almost exactly like a fixed dumbbell. No cradle required, just two stands.

Feel: NUOBELL wins. It is shorter at heavy weights, the grip diameter is traditional, and the rotating collar means you can adjust it mid-set without a cradle.

Speed: Roughly equivalent to Bowflex — both are fast.

Max weight: NUOBELL tops out at 50 lbs versus 52.5 for Bowflex — a rounding error in practice.

Price: NUOBELL costs significantly more than the SelectTech 552. The premium is real and not necessarily justified unless the traditional feel is important to you.

Verdict: If you want the most natural dumbbell feel and will pay for it, NUOBELL. For most people, the Bowflex gives you 95% of the experience at a lower price.

Bowflex 552 vs. SelectTech 1090

The SelectTech 1090 is the same dial system scaled to 90 lbs per dumbbell. If you regularly press or row over 50 lbs per hand, it is the obvious next step.

The 552 has a wider range of fine increments in the lower weights, which makes it better for general training. The 1090 makes more sense for intermediate-to-advanced lifters who have genuinely outgrown 52.5 lbs. If you are buying your first adjustable set and you currently press in the 30–50 lb range, get the 552. If you are already working with fixed dumbbells in the 55–80 lb range, go straight to the 1090.

Who Should Buy the Bowflex SelectTech 552

Buy these if:

• You are building a home gym on a limited floor budget and need the most space-efficient dumbbell solution available
• Your current training uses dumbbells up to approximately 50 lbs per hand
• You value fast weight changes for circuits, supersets, and metabolic training
• You are a beginner to intermediate lifter who will benefit from the 2.5 lb increment range
• You are disciplined about equipment care — controlled re-racking is a non-negotiable habit for you

Skip these if:

• You regularly train with dumbbells over 50 lbs (consider the SelectTech 1090 or PowerBlock Elite 90)
• You do Olympic-style or ballistic dumbbell movements (swings, cleans, snatches)
• You share your gym with people who are careless with equipment
• You want a fixed-dumbbell feel and are willing to pay more for it (look at NUOBELL)
• You are on a strict budget and can find used fixed dumbbells for less per pound

For the best adjustable dumbbells overall, the 552 consistently ranks at the top for the combination of usability, versatility, and value.

Space and Setup Requirements

Each dumbbell with its cradle takes up approximately 16.5 x 8.5 inches of floor space. Both cradles side by side require roughly 33 x 8.5 inches — a footprint smaller than a single tier of a commercial dumbbell rack. If you use the optional stand (sold separately), you add about 14 inches of height but gain ergonomic pickup height that your lower back will appreciate.

The pair weighs approximately 105 lbs total including all plates and cradles. Not something you are moving around every week, but manageable for initial setup.

Price-to-Value Analysis

The SelectTech 552 has gotten more expensive over the years. At its current street price, buying an equivalent set of fixed dumbbells from 5 lbs to 52.5 lbs would cost two to three times as much and require a rack plus significant floor space. For the functionality delivered, the 552 remains strong value — but it is no longer cheap. Watch for sales, especially in Q4 and January.

If you find a used pair in good condition for significantly less, buy it. The mechanism either works or it does not — ask the seller to dial through every weight on both ends before you commit.

Final Verdict

Rating: 4.3/5

The Bowflex SelectTech 552 is the best all-around adjustable dumbbell for most home gym owners. The dial mechanism remains the fastest and most intuitive weight-change system on the market. The 2.5 lb increments in the lower range are legitimately useful for progression. The footprint is unmatched for what you get.

It is not perfect. The fragility under drops is a real limitation that requires a behavioral adjustment — you have to treat these like precision instruments rather than gym equipment. The 5 lb jumps above 25 lbs leave a gap in the upper isolation range. And at max weight, the length is slightly awkward for certain pressing angles.

But those are manageable tradeoffs. For a home gym lifter who trains with dumbbells up to roughly 50 lbs per hand, does not do ballistic movements, and is disciplined about equipment care, this is the correct buy. The competition has gotten better, but the SelectTech 552 has not gotten worse. It is still the standard.
