Six months ago, I walked into my cluttered garage and couldn't even see my car. Twenty-six dumbbells scattered across the floor, ranging from 10 to 50 pounds, had basically turned my home gym into an obstacle course. My wife wasn't thrilled about the situation either.
That's when I decided to test the Bowflex SelectTech 552 Dumbbells – those space-saving adjustable weights everyone talks about. After putting them through rigorous workouts for half a year, I'm ready to share everything: the good, the frustrating, and whether they're worth your hard-earned cash.
Here's the spoiler: they're not perfect, but they solved my biggest problem while creating a few new ones I didn't expect.
First Look: Unboxing and Initial Setup
When the delivery truck pulled up, I knew I was in for something different. The box weighed 115 pounds – that's both dumbbells plus their cradles. Honestly? I was expecting them to feel more premium right out of the gate.
The SelectTech 552s have this industrial look with black polymer plates and metal weight discs inside. They're not ugly, but they won't win any design awards either. Each dumbbell measures 17 inches long by 8 inches wide by 9 inches high when fully assembled.
Setup took about 20 minutes, mostly reading the manual to understand how the dial system works. The instruction booklet is actually pretty clear – something I can't say about most fitness equipment I've assembled.
My first impression? These feel substantial in your hands. At the minimum 5-pound setting, there's still a decent heft to them. But here's what surprised me: they're longer than traditional dumbbells. Way longer. This becomes important during certain exercises, which I'll get into later.
Features: What Makes These Different
The headline feature is obviously that dial system. Turn the red dial on each end to your desired weight, lift the dumbbell out of its cradle, and you're good to go. The available weights are 5, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 30, 35, 40, 45, and 50 pounds, with a maximum of 52.5 pounds per dumbbell.
Let me break down what I've learned about each key feature:
The Dial System
This is where the magic happens – or where things can go wrong. Each dumbbell has two dials (one on each end) that select which weight plates come with you when you lift. The mechanism is actually pretty clever: metal pins engage with selected plates while leaving the others behind in the cradle.
In my testing, the dials work smoothly about 95% of the time. That other 5%? Sometimes they stick, especially if you don't place the dumbbell back perfectly in its cradle. I've had to wiggle them a few times to get the mechanism to engage properly.
Weight Distribution and Feel
Here's something most reviews don't mention: these don't feel exactly like traditional dumbbells. The weight plates are distributed along a 17-inch handle, so the balance point changes depending on your selected weight. At lower weights, they feel more front-heavy. At higher weights, the balance improves significantly.
During bicep curls, this isn't noticeable. But during exercises like Turkish get-ups or single-arm snatches? You definitely feel the difference. Not bad, just different.
Storage Cradles
The included cradles are simple but effective. They hold the dumbbells at a comfortable height for most people – no more bending over to grab weights off the floor. Each cradle measures about 18 inches long, so you'll need at least 3 feet of width to store them side by side.
What I like: the cradles have rubber feet that don't slide around, even on my smooth concrete floor.
What I don't like: there's no weight storage for the plates that aren't selected. They just sit in the cradle, which can look cluttered.
Performance Testing: 6 Months of Real Workouts
I've put these through everything: heavy compound movements, high-rep metabolic circuits, slow controlled movements, and explosive exercises. Here's what I discovered during my testing.
Strength Training Performance
For traditional strength exercises like chest press, rows, and shoulder press, these perform almost identically to fixed-weight dumbbells. The 52.5-pound maximum isn't limiting for most people's upper body work, though serious lifters might outgrow them quickly.
During bench press, I can comfortably handle the 52.5-pound setting for sets of 8-12 reps. The longer length actually helps with stability on the bench – there's more surface area resting against your body.
One issue I noticed: during heavy bent-over rows, the extended length sometimes bumps into my legs at the bottom of the movement. Traditional dumbbells don't have this problem.
Circuit Training and Metabolic Work
This is where the SelectTech 552s really struggle. During high-intensity circuits where I need to change weights quickly, the 15-20 seconds it takes to adjust both dumbbells kills my heart rate momentum.
I tried using them for a CrossFit-style workout that called for weight changes every 3 minutes. By the third round, I was frustrated enough to grab my old fixed weights from storage.
For steady-state workouts where you stick with one weight for an entire exercise? They're fantastic.
Range of Motion Considerations
The extended length creates clearance issues during some exercises. Chest flyes feel awkward because the dumbbells are more likely to clank together at the top. Single-arm rows require more careful positioning to avoid hitting your torso.
However, this same length provides better leverage during exercises like skull crushers and overhead extensions. It's a trade-off.
PowerBlocks Elite EXP
The main alternative that offers faster weight changes and expandability up to 90 pounds.
- Pin-based system changes weight in 3-5 seconds
- More compact design saves additional space
- Expandable with add-on kits for heavier lifters
Durability: How They've Held Up
After six months and roughly 150 workout sessions, I can report on real-world durability. Overall, they're holding up well, but there are some concerns.
What's Wearing Well
The weight plates themselves show minimal wear. The polymer coating has a few scuffs from being placed back in the cradles, but nothing that affects function. The metal plates inside are completely unaffected – they're the same quality as what you'd find in commercial dumbbells.
The handles have maintained their grip texture. I was worried they'd become slippery with use, but the diamond knurling is still sharp enough to provide good traction, even during sweaty sessions.
Areas of Concern
The dial mechanism is showing signs of wear. Both dumbbells now require slightly more force to turn the dials, and I can hear more mechanical noise during adjustments. It's not problematic yet, but I can see how this might become an issue after a year or two of heavy use.
One of my cradles developed a small crack in the plastic near the left dial area. It doesn't affect function, but it happened after I accidentally dropped a dumbbell back into place from about 6 inches up. These definitely need to be placed gently, not dropped.
Maintenance Requirements
Bowflex recommends periodic cleaning of the dial mechanism, which I've done monthly using a dry cloth. I also apply a small amount of 3-in-1 oil to the moving parts every few months, though this isn't mentioned in the manual.
The biggest maintenance issue? Keeping them in their cradles properly. If you don't seat them correctly, the dials can jam or become difficult to turn. I learned this the hard way during week two.
Value: Breaking Down the Investment
Let's talk money. A pair of SelectTech 552s typically costs between $300-400, depending on sales and retailer. That's a significant investment, so let's see how it stacks up.
Cost Comparison
If you bought individual dumbbells to match the SelectTech range (5 to 52.5 pounds in 2.5-pound increments), you'd need 20 pairs. At current prices, that's roughly $1,200-1,500 worth of fixed weights, not including a storage rack.
From a pure dollars-and-cents perspective, the SelectTech 552s are absolutely a better value. You save about $800-1,100 compared to buying equivalent fixed weights.
Space Value
This is where these really shine. My old dumbbell collection required a 6-foot rack and about 15 square feet of floor space. The SelectTech pair needs just 3 feet of width and maybe 2 square feet total.
If you're paying for a gym membership partially because you don't have space for home weights, the SelectTech 552s could pay for themselves in 3-4 months of cancelled memberships.
Time Value
Here's where it gets tricky. For steady workouts, these save time because everything's organized and accessible. But for quick weight changes? Fixed dumbbells are faster.
I timed myself: grabbing a different fixed dumbbell takes 3-5 seconds. Adjusting the SelectTech takes 15-20 seconds per dumbbell. That adds up during circuit training.
NordicTrack Select-A-Weight 55
Similar functionality to the SelectTech 552 but typically priced $50-100 lower with comparable weight range.
Long-Term Investment
The 2-year warranty is decent but not exceptional. Based on my experience so far, I expect these to last 3-5 years with regular use, assuming the dial mechanism doesn't fail prematurely.
Replacement parts aren't readily available, which concerns me. If a dial breaks after the warranty period, you're probably looking at buying a new set.
Verdict: Who Should Buy These?
After six months of daily use, I can confidently recommend the Bowflex SelectTech 552s to specific types of users while warning others away.
Perfect For:
- Home gym builders with limited space: If you're working with a small area, these are game-changers. The space savings alone justifies the cost.
- Beginner to intermediate lifters: The weight range covers most people's needs for upper body training, and the incremental adjustments are perfect for progression.
- People who do structured workouts: If you follow planned routines where you stick with one weight per exercise, the dial system isn't a limitation.
- Anyone replacing a gym membership: These pay for themselves quickly if you're canceling monthly gym fees.
Not Ideal For:
- Circuit training enthusiasts: The 15-20 second weight change time kills workout flow during high-intensity sessions.
- Heavy lifters: The 52.5-pound maximum isn't enough for serious strength athletes, especially for lower body work.
- People who drop weights: The dial mechanism requires gentle handling. If you're rough with equipment, these won't last.
- Apartment dwellers with noise concerns: While not extremely loud, placing them back in cradles does create some noise.
My Personal Recommendation
Would I buy them again? Yes, but with realistic expectations. They solved my space problem completely and provide enough weight variety for 90% of my workouts. The remaining 10% – high-intensity circuits and super heavy lifts – I handle with other equipment.
They're not perfect dumbbells. They're a space-saving compromise that works really well for most people most of the time. If you understand their limitations going in, you'll be satisfied with the purchase.

Frequently Asked Questions
How much space do SelectTech 552 dumbbells save compared to traditional weights?
The SelectTech 552s require just 3 feet of width and about 2 square feet of floor space total. An equivalent set of fixed dumbbells (15 pairs from 5-52.5 lbs) would need a 6-foot rack and approximately 15 square feet of floor space. That's roughly 85% space savings, making them ideal for home gyms, apartments, or garage setups where space is premium.
Are the SelectTech 552 dumbbells durable for heavy daily use?
After six months of daily use in my testing, the dumbbells are holding up well structurally, but the dial mechanism is showing some wear. The weight plates and handles remain in excellent condition, but both dials now require slightly more force to turn and make more noise during adjustments. With gentle handling and proper maintenance, I expect 3-5 years of reliable use for most home gym users.
How quickly can you change weights with the SelectTech dial system?
Weight changes take 15-20 seconds per dumbbell in my experience. You need to place the dumbbell in its cradle, turn both end dials to the desired weight, and lift it out. This is significantly slower than grabbing different fixed weights (3-5 seconds), making them less ideal for circuit training or workouts requiring frequent weight changes. For structured workouts where you use one weight per exercise, the adjustment time isn't problematic.
Do SelectTech 552 dumbbells feel balanced during exercises?
The balance point changes depending on your selected weight due to the 17-inch length and distributed weight plates. At lower weights (5-15 lbs), they feel slightly front-heavy compared to traditional dumbbells. At higher weights (35+ lbs), the balance improves significantly. This affects some exercises more than others – chest flyes and single-arm movements feel different, while bicep curls and shoulder presses feel nearly identical to fixed weights.
What's the warranty coverage and customer service experience?
Bowflex provides a 2-year warranty on parts and mechanisms for the SelectTech 552 dumbbells. The warranty covers manufacturing defects and mechanical failures but not damage from drops or misuse. Customer service response has been generally positive based on user reports, though replacement parts aren't readily available for purchase separately. If the dial mechanism fails after warranty, you'll likely need to replace the entire unit.
Are there exercises you can't do with SelectTech dumbbells?
The extended 17-inch length creates limitations for certain exercises. Chest flyes are awkward because the dumbbells clank together more easily. Single-arm rows require careful positioning to avoid hitting your torso. Turkish get-ups and snatches feel different due to the distributed weight. However, they work excellently for most traditional exercises like bench press, shoulder press, bicep curls, and rows. The limitations are manageable for most home gym users.
How do SelectTech 552 compare to other adjustable dumbbell brands?
Compared to PowerBlocks, the SelectTech 552s have a more traditional dumbbell feel but slower weight changes. PowerBlocks adjust in 3-5 seconds vs 15-20 seconds for SelectTech. Ironmaster Quick-Locks are more durable and expandable to higher weights but cost significantly more. NordicTrack Select-A-Weight offers similar functionality at a lower price but with less refined build quality. The SelectTech 552 strikes the best balance of feel, features, and value for most users.
