PowerBlock Vs Bowflex: I Tested Both To Find Out Which One Is The Better Adjustable Dumbbell!

PowerBlock vs Bowflex

The adjustable dumbbell scene has been dominated by two giants- PowerBlock and Bowflex- for over a decade. But which brand is actually better? This post is a hands-on comparison between PowerBlock vs Bowflex dumbbells.

Most people would agree that PowerBlocks are better than Bowflex. PowerBlocks have a superior weight capacity, increments, handle, compactness, durability, and warranty compared to Bowflex. However, both dumbbells are still very good and a decision should be made based on personal preference.

I bought the PowerBlock Elite (review here) and the Bowflex SelectTech 552 (review here) to pit them against each other.

I also conducted a series of online studies to find out what other people think.

You can keep reading to find out the results of my comparison!

I tested the Powerblock and Bowflex dumbbells to find out which is better.

Materials And Aesthetics Comparison

Materials and aesthetics comparison between PowerBlock vs Bowflex.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Urethane-coated plates (Pro series only) are chip-resistant, unlike Bowflex’s polypropylene.Heavy-duty polypropylene plates are more durable than PowerBlocks powder-coating.
More suitable for those who prefer an industrial-look dumbbellMore suitable for those who prefer a modern-looking dumbbell with a traditional shape.

My Choice:



At the end of the day, looks and aesthetics are primarily subjective qualities.

Which dumbbell you prefer the look of really depends on your tastes.

I favor the PowerBlock’s no-nonsense look, but you may rather choose Bowflex’s modern-looking design.

Superficial reasons aside, the weight plate materials on both dumbbells DO offer performance benefits and drawbacks:

  • PowerBlock Elite/Sport powder-coating. Keeps the price low but can scratch, chip, and rust if the dumbbell is dropped. Also, does not offer protection for flooring.
  • PowerBlock Pro urethane-coating. The most resistant material to knocks, scratches, and protects your floor. But comes with a premium price tag.
  • Bowflex SelectTech Polyurethane coating. Similar qualities to PowerBlocks urethane-coating but slightly less durable and more prone to chipping.

It’s a close competition between PowerBlock vs Bowflex when it comes to material durability.

The urethane-coating on PowerBlock Pros is harder-wearing compared to the polypropylene in Bowflex dumbbells, which is, in turn, more durable than the powder-coating on PowerBlock Elites/Sports.

It really depends on which models you’re comparing!

PowerBlock Vs Bowflex: Dumbbell Shape Comparison

Shape comparison between PowerBlock vs Bowflex.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Block-shape made from steel rails is generally more durable than the Bowflex design.Traditional dumbbell shape gives a similar feel and weight distribution to commercial gym dumbbells.
Open-handle shape allows greater variety in the way you hold the dumbbell compared to PowerBlocks’ closed-handle design.

My Choice:



In terms of lifting ergonomics, you can’t go wrong with the traditional dumbbell shape offered by the Bowflex dumbbells.

After all, dumbbells have been manufactured to the same design for hundreds of years.

A traditional dumbbell shape effectively distributes the weight to both ends of the handle. It also gives you an open-handle design (where your hand can reach the dumbbell handle from all angles).

The Bowflex open-handle design is better than PowerBlocks closed-handle design.

Combined, this replicates the feel of a commercial gym dumbbell which many people find important.

In comparison, PowerBlocks have all the weight concentrated directly onto the handle. This can make exercises utilizing an off-center grip, like the supinated dumbbell curl, feel slightly awkward when you’re already familiar with gym dumbbells.

PowerBlocks also have a series of rails running across the dumbbell in a closed-handle design.

A good example of this is the foam-padded handle guards on the PowerBlock Elites.

The PowerBlock closed-handle design.

This can be awkward when it gets in the way during some exercises that utilize unconventional grips (e.g. the dumbbell pull-over).

With all this said, the PowerBlock shape IS much more durable compared to the Bowflex.

But overall, Bowflex gets a slight win over PowerBlock on this one I’m afraid.

Weight Adjustment Mechanism Comparison

Weight adjustment mechanism comparison between PowerBlock vs Bowflex.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Pin-selector adjustment mechanism never gets stuck, which can happen on Bowflex dials.Bowflex dial mechanism is more beginner-friendly and intuitive compared to PowerBlocks pin-selector.
Dial-selector is generally more durable compared to PowerBlocks polypropylene pin-selector

My Choice:



In my opinion, you can’t really beat the intuitiveness of Bowflex’s simple dial system; just turn the knob to choose your desired weight.

In comparison, the PowerBlock pin-selector system needs to be used in conjunction with a color weight chart. And if you’re not familiar with the coding stem, it can be rather slow to adjust the correct weight.

But once you’ve familiarised yourself, it becomes second nature.

Once you’ve gotten used to the PowerBlock adjustment mechanism, the speed at which both dumbbells change weight is more or less similar:

Adjustment Speed MetricPowerBlockBowflex
2.5lb to 5lb adjustments7 seconds2 seconds
10lb adjustments2 seconds2 seconds
5lb to 50lb adjustment2 seconds2 seconds

However, where the PowerBlocks adjustment speed suffers, is in their adder weight adjustments.

You need to pull the handle cavity out of the main weight nest to insert/remove the adder weights to adjust in 2.5/5lbs.

Whilst the adder weight function is awesome, it can be slow and cumbersome to use, even with PowerBlocks auto-lock switch which was designed to make the process faster.

In comparison, the Bowflex dumbbells are quick to adjust in all weight ranges.

That’s why I think the Bowflex is better than the PowerBlock on this front, despite some of the durability issues reported by some customers.

PowerBlock Vs Bowflex: Max Weight And Increments Comparison

PowerBlock vs Bowflex max weight and increments comparison.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Elite/Sport/Pro 50 EXP models are expandable to 90lbs per dumbbell, unlike the Bowflex 552.Bowflex 552 has a 12.5lb setting which is unavailable in most PowerBlock models (except Sport 24 and Pro 32). This weight is great for beginner bicep curls.
Base models can be expanded whenever the user is ready and this gives greater flexibility and affordability for owners, unlike Bowflex dumbbells.
EXP models allow 2.5lb increments across the entire weight range (2.5lb-90lb) unlike the Bowflex dumbbells.
PowerBlocks replace up to 28 dumbbells, which is 11 more than Bowflex’s best model (SelectTech 1090).

My Choice:



PowerBlock’s main selling point is its durability and awesome weight settings.

It’s built for those who need to lift heavy or beginners who intend to lift heavy in the future.

For most people, the PowerBlock expandable (EXP) models offer excellent value for money (they’re not a lot more expensive than non-EXP models).

How the PowerBlocks can expand weight unlike Bowflex.

All models in this PowerBlock EXP series give you a base weight of 2.5-50lbs in 2.5lb increments (using the adder weights) and replaces 16 dumbbells.

This is similar to the Bowflex 552.

But where the PowerBlock outshines the Bowflex is in their ability to be expanded up to 90lbs per dumbbell.

This means you have the option to upgrade if and when you outgrow the current weight, without being forced to spend close to $1000 on a 90lb dumbbell (like the Bowflex 1090) right from the get-go.

Bowflex dumbbells cannot be expanded.

In comparison, the Bowflex weight structure is more rigid and forces you to go for either a 52.5lb dumbbell or a 90lb dumbbell.

And if you do happen to find it too heavy/light after purchase, then tough, you’ll have to stick with it or purchase a new pair of dumbbells to upgrade.

Additionally, PowerBlock EXPs give you 2.5lb increments across the entire weight range, compared to Bowflex 552 dumbbells which only give you 2.5lb increments up to 25lbs (Bowflex 1090 dumbbells don’t offer 2.5lb increments at all).

PowerBlocks 2.5lb adder weight function is better than Bowflex.

Without 2.5lb increments, it becomes slightly harder to make smooth strength gains in small exercises like the bicep curl, lateral raise, and tricep extension.

Finally, PowerBlock dumbbells generally replace a higher number of dumbbells compared to their equal Bowflex competitor.

These reasons combined, allow me to confidently say that PowerBlocks weight settings are far better than the Bowflex dumbbells.

Handle/Grip Comfort Comparison

Bowflex vs PowerBlock handle comparison.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Grip covers the entire dumbbell handle, unlike the Bowflex dumbbells.Open-handle design feels more like a traditional dumbbell handle compared to PowerBlocks
TRP material provides more grip compared to Bowflex dumbbells.36mm handle diameter is more comfortable for smaller hands.
38mm handle diameter is great for the average hand size.

My Choice:



This was a close call but I had to go with the PowerBlock and here’s why.

Firstly, the handle diameter between the PowerBlock and Bowflex are similar. The 2mm difference means the Bowflex handle is slightly better for people with small hands (< 4″ clenched fist diameter).

But to be honest, the difference is minimal and you’ll not be able to notice unless you’re comparing both dumbbells side by side.

PowerBlock off-centre grip is better than Bowflex.

Secondly, the grippy material covers the entire PowerBlock handle. In comparison, the grippy material only covers a portion of the Bowflex handle.

This makes a big difference when you’re doing exercises that use an offset grip (e.g. tricep extensions and supinated bicep curls) since the Bowflex offers very little grip when the handle is held off-center.

I performed a grip test on my PowerBlock and Bowflex dumbbells to find out which had the better handle.

Thirdly, I performed a simple test to find out which handle material provides the better grip– PowerBlocks TRP (thermoplastic rubber) vs Bowflex’s textured neoprene sleeve.

The test involved using my index finger and thumb to pinch the handle of each dumbbell set at 10lbs with just enough force to pick it up.

I then lifted it from the floor and timed how long I could hold the dumbbell (longer = more grip):

You can see the PowerBlock performed better on my grip test.

So overall, I do feel the PowerBlock handle gets a slight edge over and is better than, the Bowflex handle.

PowerBlock Vs Bowflex: Compactness And Space-Savings Comparison

PowerBlocks vs Bowflex dimensions and space-savings comparison.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Compact block-shaped design generally feels much less bulky and awkward during exercises, compared to the Bowflex.Comes with a storage cradle that protects the dumbbell and your floor.
Occupies around 25% less cubic volume compared to Bowflex dumbbells, making them better for small home gyms.
Can be stacked on top of one each other during storage.

My Choice:



Most customers feel that the Bowflex dumbbells are generally worth the money.

But one of their biggest issues is their sheer bulk.

Take the Bowflex 552 for example- the dumbbell measures 17″ from end to end, compared to the PowerBlock Elite which measures 12″.

PowerBlock is much more compact compared to Bowflex dumbbells.

What’s even worse though, is the fact that the Bowflex dumbbells don’t get shorter as the weight gets lighter (as PowerBlocks and fixed-weight hex dumbbells do).

This means the Bowflex dumbbells often bump into each other during small movements like the bicep curl.

This makes them feel awkward and sometimes incredibly frustrating to use.

PowerBlocks save more space in storage compared to Bowflex dumbbells.

Storage-wise, the PowerBlocks win again.

Not only are they more compact in all dimensions, but they can also be safely stacked on top of each other when not being used (perfect for small spaces).

However, one negative to point out with the PowerBlock Elite/Sports is that the steel rails sit directly on the floor.

This can scratch hardwood and tiled flooring if you aren’t careful.

But overall, I’d say the PowerBlocks are still much better with regards to their overall compactness and size.

You can check out my other post for more details on the differences between each PowerBlock and which one is the best.

Sturdiness And Durability Comparison

PowerBlock vs Bowflex durability and sturdiness comparison.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Steel rail block design is extremely durable for an adjustable dumbbell.Bowflex propylene weight plates are more scratch resistant compared to PowerBlock Elite/Sport powder-coating.
Can safely take body weight in exercises like the dumbbell push-up unlike Bowflex dumbbells.

My Choice:



For me, the clear winner is PowerBlock.

Bowflex dumbbells aren’t exactly flimsy. OK the weight plates rattle on the handle, they can’t be dropped, and you can’t lean your body weight on them in exercises like the dumbbell-push up.

However, if you look after them, they’ll last you a long term (my Bowflex SelectTech 552s have lasted me over 2 years now).

PowerBlocks are sturdy enough to support body weight.

But the PowerBlocks block design is definitely superior.

My PowerBlock Elites genuinely feel like they can take a pounding despite being the cheapest PowerBlock model.

I can safely lean my entire body weight on them and even drop them without the slightest sign they’ll break (not that I recommend you abuse this).

The only negative about PowerBlock’s durability is in their weight plate outer coating.

PowerBlock powder-coating is not as durable as Bowflex heavy-duty plastic.

On the cheaper models (Elite and Sport), the weight plates are powder-coated in thick enamel paint.

Whilst this is generally quite hard-wearing, it is by no means invincible to scratches and chips (not an issue with the Pro series urethane-coated plates).

In contrast, the polypropylene Bowflex plates are much more scratch-resistant.

But overall, I feel the Powerblocks are much better than the Bowflex dumbbells in terms of general resilience.

PowerBlock Vs Bowflex: Shipping And Warranty Comparison

Bowflex vs Powerblock shipping and warranty comparison.

PowerBlock Vs Bowflex Head-To-Head:

Why PowerBlock Is BetterWhy Bowflex Is Better
Extended 5-year warranty compared to Bowflex’s 2-year warranty.Ships in 1 parcel reducing the risk of transit issues.
More likely to be in stock on Amazon.

My Choice:



Both the PowerBlocks and Bowflex dumbbells are designed in the USA and made in China.

The shipping process is also similar for both dumbbells, taking just under 2 weeks and up to $200 for international delivery on Amazon (US shipping takes around 1 week and is free of charge).

The main difference comes down to the fact that PowerBlock dumbbells ship in two boxes (not a major issue since they both arrived with less than a days lag) and Bowflex dumbbells are delivered in a single box.

They are both sold in pairs.

It’s the warranty policy that sets these two dumbbells apart.

All PowerBlock comes with an industry-leading 5-year warranty that also covers damage as a result of drops less than 12″ in height.

In comparison, Bowflex only offers 2-years and does not cover damages as a result of drops.

So you can probably understand why I would say that PowerBlocks are much better than Bowflex dumbbells in terms of the warranty policy!

Right from the bat, the most noticeable difference seems to be that Bowflex dumbbells are much more popular than PowerBlocks.

However, these numbers should be treated with caution.

PowerBlock sells its dumbbells on its website as well as on Amazon. Additionally, they seem to have more authorized retailers compared to Bowflex.

Therefore PowerBlock sales on Amazon are likely not a true reflection of the number of units sold.

Furthermore, speaking from experience, I can say that Bowflex dumbbells are always available on Amazon; unlike PowerBlocks which are often out of stock.

There was no statistically significant difference between the % of reviews >4*/<2*.
