With such a large variety of dumbbells on the market, it’s easy to become stuck in analysis paralysis when choosing the perfect dumbbells. Can you relate? Keep reading if you can. Because today I’ll be sharing 9 of the heaviest adjustable dumbbells you can get to build muscle!

Let’s jump right in.

First, here’s the quick lowdown:

Ativafit Dialtech 71.5 Adjustable11-71.5lb175.5lb$500£664 (amazon import)

Next, I’ll examine the pros and cons for each of these heavy-hitting dumbbells.

Being adjustable dumbbells, they all share common advantages:

  • Compact with a low footprint.
  • Quick weight changes.
  • Replaces an entire dumbbell set.
  • Ready to use out the box.
  • Versatile and can be used to train all muscle groups.
  • Relatively cheap compared to a fixed-weight dumbbell set.

Therefore I won’t include these in my analysis. Instead, I’ll only make points specific to each dumbbell.

Note: I’ve personally used and tested some of these dumbbells and others I rely on peer review. This will be made clear throughout the article!

1) Ironmaster Quick Lock – 165lbs.

ironmaster quick lock 165 is the heaviest adjustable dumbbell on the market

What They Are:

Remember in The Terminator movies how the robots just would not bloody die?

Well, that’s what the guys at Ironmaster have created- the dumbbell equivalent of the T-800.

“The worlds strongest adjustable dumbbell”

Ironmaster

Not only are the Ironmaster Quick Lock 165’s extremely resilient, due to the welded steel and iron design, but they are also very heavy.

In fact, they are the heaviest adjustable dumbbells on the market (as far as I know).

ironmaster dumbbells are extremely durable

The standard set weighs 75 pounds, but you have the option to upgrade to 120 and 165 pounds with their expansion kits.

The patented quick-lock screw system is a hybrid between a selectorized and spinlock adjustable mechanism.

And this allows you to quickly change weights.

Finally, they are moderately sized at 59.5cm x 16.5cm (23.5″ x 6.5″).

Why They Are Great:

  • Heaviest adjustable dumbbells you can get. Great if you want to lift heavy and build big muscle at home.
  • Looks and feels like a classic dumbbell. Perfect for the hardcore traditionalists.
  • Barbell-style handle. Solid steel with knurling (the ethcing on the handle) is a great feature for experienced lifters.
  • Solid steel and iron construction. No plastic components. Makes them virtually indestructible.
  • Flat endcaps can rest on the thigh. Important for exercises like the dumbbell bench press where the dumbbell needs to be kicked up.
  • Anti-roll square shape. Prevents them from rolling on sloped surfaces.

The Problems:

  • Very expensive. They are the heaviest adjustable dumbbells you can get, but also cost an arm and a leg.
  • Quick lock mechanism is not the fastest. Dial and pin selectorized adjustable dumbbells feature quicker weight changes.
  • Long dumbbell length. These dumbbells are long from end-to-end and this can feel awkward for exercises like the bench press as they bump into each other.
  • Requires math to select weight. These don’t have weight readouts, unlike the other adjustable dumbbells which have marked readouts.

Compared To The Other Heaviest Adjustable Dumbbells:

Ironmaster Adjustable Dumbbells Review: The Lifters Choice!

If you want the absolute heaviest adjustable dumbbell for your home gym, then these are ideal for you.

But they won’t come cheap.

The expansions required to take the Ironmasters to 165 pounds will cost $1477. And it’s even more expensive if you live in the UK (£1477).

That’s almost double the price of the other Premium brands (Bowflex and Powerblock).

But you get what you pay for.

And the competitors don’t even come close when it comes to overall weight, durability, and traditional look/feel.

2) Bowflex SelectTech 1090 – 90lbs.

Bowflex 1090 is one of the heaviest adjustable dumbbells in uk and usa

What They Are:

Bowflex is the OG of the adjustable dumbbell world.

Think of them as the equivalent to what Nike is in the world of sneakers.

The Bowflex SelectTech 1090 is the heaviest in the entire Bowflex adjustable dumbbell range.

They pack 17 different weights into a single 44cm x 24cm (17″ x 9″) unit.

The maximum and minimum weight is 90 pounds and 10 pounds, respectively.

both dials on the bowflex 1090 adjust each side independently

Weight changes are made using the dual-dial mechanism. Each dumbbell has 2 dials on either side controlling the weight on that particular side of the dumbbell.

Why They Are Great:

  • Sharp-looking design. Anyone else think these look like a dumbbell Optimus Prime would use?!
  • Quick weight changes. The dial-a-weight- mechanism is quick and intuitive (great for super sets and drop sets).
  • Anti-roll flat bottom. Prevents a heavy dumbbell from rolling on sloped surfaces.
  • Rounded end-caps. These are comfortable when rested on the thigh.
  • Traditional dumbbell shape. They can be used to replicate all dumbbell exercises including ones that use unconventional grips (like the overhead tricep extension).
  • Solid rotating handle with different grip choices. You can choose to have your grip resting on a knurled or smooth surface.
  • Dual weight adjustments on both sides of each dumbbell. Great for exercises which benefit from an uneven weight distribution (e.g. overhead extensions where it helps to have less weight plates on the bottom side).

The Problems:

  • Long length at lower weights. The length of the 1090’s remains the same regardless of weight. This can be awkward for smaller exercises such as the bicep curl.
  • Thick handles are not liked by all. The handle is thicker than traditional fixed-weight dumbbells and can be hard to grip at heavier weights.
  • Rotating handles can dig into your hands. This is especially annoying when using the heavier weight settings.
  • Plates need to be aligned when placed into the cradle. Otherwise the dumbbell can scratch or get stuck which can be tedious during workouts.
  • Fragile for a heavy adjustable dumbbell. It comes with a “do not drop” label which is something you’d expect to happen when lifting heavy dumbbells right?!

I BOUGHT THE BOWFLEX 1090 DUMBBELLS | REVIEW

If you live in the UK- the Bowflex 1090’s are the cheapest and best adjustable dumbbells in the UK that are from the premium brands (Ironmaster, Bowflex, and Powerblock).

That’s because the Powerblock Elite series (cheapest in US) is not currently available to UK residents, and needs to be imported.

So if you’re a Brit who’s after one of the heaviest adjustable dumbbells with a strong brand name and a good price, then these are for you.

Adjustable DumbbellMax WeightUS PriceUK Price
Ironmaster Quicklock 165165lb$1447£1447
Powerblock Pro EXP 70-90 90lb$817£910
Bowflex SelectTech 109090lb$799£750
Powerblock Elite USA 70-9090lb$627£1079 (ebay)

These 90-pound adjustable dumbbells will allow you to do heavy home workouts.

I’ve personally tested these, and they are awesome for heavy compound lifting. And the quick weight changes are great for quick workouts.

But the durability seems to be lacking when compared to the Ironmasters and Powerblocks.

So make sure you look after them!

3) Powerblock Pro Series – 90lbs.

Powerblock pro is expensive for a 90lb adjustable dumbbell

What They Are:

Powerblock is a company that started in 1993 and they are the other OG of adjustable dumbbells.

Where Bowflex is Nike, Powerblock could be considered the Adidas of the adjustable dumbbell market.

The Powerblock Pro series weighs in at 50-pounds standard.

But you have the option to upgrade to 90-pounds with the stage 1 and stage 2 kit (both required to create 90-pound adjustable dumbbells).

pin-select mechanism for the powerblock pro

It uses a pin mechanism to adjust the weight.

This replaces 28 weights you would otherwise have to purchase if you were to buy individual dumbbells.

And all this is packaged into a small 32cm x 18cm (12.5″ x 7″) unit!

Why They Are Great:

  • Lowest footprint of all the adjustable dumbbells. They have a 45% less cubic volume than the Bowflex 1090’s.
  • Great warranty and customer support. Each dumbbell comes with a 5 year limited warranty.
  • One of the fastest weight adjustment mechanisms. The pin mechanism can change weight in seconds.
  • Pin insertion makes a satisfying click noise. To me this is a sign of good build quality.
  • Feels very durable. Solid construction and a flexible pin makes the unit feel like it will last.
  • Long padded handles. These can accommodate different hand sizes.
  • Urethane-coated steel. Makes these dumbbell less abrasive to the floor and other belongings.

The Problems:

  • Unconventional dumbbell shape. Makes the unit feel awkward to use for people who are new to Powerblocks. These aren’t the best dumbbells for exercises such as the goblet squat and overhead tricep extension.
  • Pin susceptible to damage. The pin is flexible, but will snap/bend if inserted incorrectly.
  • Relatively expensive. More costly than the Bowflex 1090’s and Powerblock Elite series.
  • Chrome tubes rattle when shaken. The tubes allow you to make 5lb increments, but rattle inside the cavity.

Compared To The Other Heaviest Adjustable Dumbbells:

Powerblock PRO EXP Dumbbells Review- Stage 1, Stage 2 and Stage 3 Kits

I’ve personally tested the Powerblock Pro, Elite, and Bowflex 1090 series.

These are all 90lb adjustable dumbbells.

The Powerblock Pro series is the most expensive, but you don’t really get much more for the money.

All 3 are some of the heaviest adjustable dumbbells you can find (only the Ironmasters go heavier) and I would personally choose the other 2 dumbbells over the Powerblock Pros.

That being said, the Pro series does feel very durable.

So if you want a heavy adjustable dumbbell with a solid feel, then spend the extra cash for the Powerblock Pro’s!

4) Powerblock Elite USA Series – 90lbs.

powerblock elite is a 90lb adjustable dumbbell which is cheaper than the elite series

What They Are:

The Powerblock Elite series is the younger brother to the Pro series (available in the US only)

The two dumbbells are very similar, only differing in build quality.

As with the older brother, the Elite series comes standard with 50-pounds which can be expanded to 90-pounds.

And just like the Pro series, the Elite’s adjust weight with a pin-selector mechanism.

Why They Are Great:

  • Small and compact unit. They have the lowest cubic volume out of all the heavy adjustable dumbbells.
  • Weight-guide label informs you how much weight is selected. Great for beginners to choose weight effortlessly.
  • Flat base prevents rolling. This makes them perfect for ground exercises like the dumbbell push-up and renegade row.
  • Cheaper than the Powerblock Pro series. And has a similar degree of functionality.
  • Quiet weight changes. The pin-selector mechanism is slick and does not cause much noise.
  • Urethane-coated steel construction. Rust-proof, durable, and non-abrasive.
  • Flat base. Can be rested comfortably on the thighs.

The Problems:

  • Structural support columns can get in the way. This restricts certain ways you can grip the dumbbell (like in the overhead tricep extension).
  • Internal handle cavity is small. Can be restrictive of you have large hands.
  • Same issues as the Elite series.

Compared To The Other Heaviest Adjustable Dumbbells:

Gyms are CLOSED, Now What | Power Block Elite Dumbbell Review | Dad’s Home Gym

For US residents- these are an awesome pair of 90lb adjustable dumbbells.

Having tested both the Pro and Elite, I would choose the Elite series purely because I don’t feel the extra cost of the Pro’s are justified (just my opinion).

For UK residents- these are only available as imports, or from Ebay (at the time of writing). And this makes them extremely pricey.

There are other UK adjustable dumbbells you should consider instead (Bowflex 1090’s, Powerblock Pros, and budget brands).

So depending on where you are buying from, the Elites could be good or bad.

But overall, the Powerblock Elites are a great pair of 90lb dumbbells.

If you’re happy with a heavy dumbbell that’s protected by a great warranty and will get the job done, then these are for you!

5) Net Fit Boss Adjustable – 90lbs.

net fit boss makes one of the cheapest and heaviest adjustable dumbbells in the us

What They Are:

The Net Fit Boss 90’s are the flagship model from this small US retailer.

At 90 pounds, they are one of the cheapest and heaviest adjustable dumbbells on the US market.

The design itself is based on the Bowflex 1090 dumbbell.

It features 17 weights that take the dumbbell from 5 pounds all the way to 90 pounds.

And the weight is selected by a dial-mechanism just like the Bowflex.

Just a heads up: these are re-branded generic dumbbells.

This means the retailer has sourced a generic dumbbell design from China and sold it as their own.

That said, they are a great way to lift heavy weights at an affordable price.

These are not available in the UK domestic market.

Why They Are Great:

  • The retailer is very old. It’s a small company but they’ve been around for a while.
  • Great price-weight ratio. At $3 per pound, they are one of the cheapest and heaviest adjustable dumbbells you can get in America.
  • Sleek and modern design. Similar looks to the Bowflex 1090’s.
  • Contoured handles with knurling. Provides the dumbbell with comfortable lifting ergonomics.
  • Anti-roll flat base. Prevents the dumbbell rolling on uneven surfaces.
  • Very cheap for 90lb adjustable dumbbells. They cost $3.05 per pound.

The Problems:

  • Small independent retailer with mixed reviews. This is not a reputable brand like Ironmaster, Bowflex, or Powerblock.
  • Fragile and can’t be dropped. Just like the Bowflex’s which they are based on.
  • 1 year limited warranty. This isn’t great for a small-time dealer with mixed reviews.
  • Generic dumbbell. Made in China and rebranded in the USA. Same design can be found from other retailers.
  • Weight plates become easily scuffed. The paintwork is not the most durable.

Compared To The Other Heaviest Adjustable Dumbbells:

These are some of the cheapest 90lb adjustable dumbbells you can buy in the US.

I’ve not personally tested them and the company themselves don’t have great reviews.

As such, I would recommend you to spend the extra $80 and go for the Powerblock Elites.

Doing this would also give you reputable customer support and a 5-year warranty from Powerblock.

6) DN Fitness Adjustable – 90lbs.

dn fitness adjustabell dumbbells are based on the nuo 80 design

What They Are:

The DN Fitness 40’s are the UK generic equivalent to the Nuobell 80’s (which you’ll see later are great adjustable dumbbells).

Being a generic model, the retailer has sourced it from China and rebranded it.

That being said, it packs a lot of features, and many dumbbells are made in China these days (even premium brands).

These are one of the more affordable and heaviest adjustable dumbbells in the UK.

They contain 17 weights which go from 10 pounds all the way to 90 pounds.

The weights are selected with a handle-turn mechanism.

Why They Are Great:

  • Mid-range adjustable dumbbell brand. Up to 30-50% cheaper than the premium brands but still offer some of the heaviest adjustable weights in the UK (when purchased at their current discounted price).
  • Handle-turn mechanism is very efficient. Makes for rapid weight changes.
  • Great design. Minimalistic and looks and feels like a traditional dumbbell.
  • 2 year warranty. Not bad for a mid-range dumbbell.
  • Great reviews. An average of 5 stars.
  • Quick and efficient customer support. User-feedback is positive.

The Problems:

  • Long length makes it awkward for some users. Expect the dumbbells to bang into each other in exercises such as the bench press and curl.
  • Relatively expensive when not on sale. At £700 RRP, you could spend an extra £50 and get yourself a pair of Bowflex’s.
  • Generic adjustable dumbbell. Based on the popular Nuobell 80’s but without the same build-quality.

Compared To The Other Heaviest Adjustable Dumbbells:

I’ve not personally tested these, but the user reviews seem great.

Worth every penny if you want to train at home, all i’ve got is a bench and a set of these and I don’t need anything else.

Jimmy (customer review)

If you’re looking for one of the cheaper (yet heaviest) adjustable dumbbells in the UK, then these are for you.

They go up to 90lbs just like the Powerblock and Bowflex, but at a fraction of the price.

In fact, these are some of the best UK adjustable dumbbells if you’re looking to lift heavy (and don’t mind them being rebranded generics).

7) Braingain Adjustable – 90lbs.

braingain makes the cheapest and heaviest adjustable dumbbell in the UK

What They Are:

The Braingain 40 adjustable is the UK equivalent of the Net Fit Boss 90 (from the US).

In fact, they are the exact same generic dumbbell sourced from China.

These are the cheapest and heaviest adjustable dumbbells you can get in the UK (at 90lbs) but come with the same drawbacks as the Net Fit Boss 90.

It uses a dial-selector mechanism just like the Bowflex 1090.

Why They Are Great:

  • Same benefits as the Net Fit Boss 90.
  • Braingain has great customer support. 100% positive user-feedback and 4.8/5 on Trustpilot.
  • Cheapest 90lb adjustable dumbbell in the UK. They cost just £2.22 per pound.

The Problems:

  • Same drawbacks as the Net Fit Boss 90.
  • 6 month warranty is not very long. Not many reviews mention the long-term durability of these dumbbells.

Compared To The Other Heaviest Adjustable Dumbbells:

Just as with the Net Fit Boss 90’s, I’ve not personally tested these.

But the reviews are generally great (5-star rating) and they are THE cheapest and heaviest adjustable dumbbells available in the UK (as far as I know).

If you want a pair of 90lb adjustable dumbbells without forking out the cash for the premium brands, then these are for you.

However, you should also be aware that the 6 month warranty won’t cover you for very long!

Go for the DN Fitness 40’s if you want a longer warranty period.

8) BWSS Nuobell – 80lbs.

Nuo 80 adjustable dumbbells use a rotating handle to change weight

What They Are:

The Nuobell 80’s are the new hit from this Swedish company.

They aren’t the heaviest adjustable dumbbell on the market, but they have one of the fastest weight-change mechanisms out there

These dumbbells go from 5 pounds to 80 pounds.

Nuo 80 rotating handle weight adjustment mechanism

The weight is adjusted by a handle-twist mechanism.

Rotating the handle causes the selected wight to click into place (which is highlighted by a rectangular readout).

It also looks and feels just like a traditional dumbbell.

Why They Are Great:

  • Fastest weight change mechanism. Adds up to quicker workouts.
  • Satisfying clicking sound from weight changes. Indicates a great build quality.
  • Traditional dumbbell shape. Great for exercises like the overhead tricep extension and goblet squat which requires you to hold the dumbbell using an unconventional grip.
  • Straight knurled and steel-welded handle. Feels like a barbell handle.
  • 80lb max capacity. Not the heaviest, but still heavy enough for most peoples needs.
  • Machined iron weight plates. These are very sturdy and long-lasting.
  • 2 year limited warranty. Long-term protection.

The Problems:

  • Not the heaviest adjustable dumbbell on the market. Go for 90lb dumbbells if you need a heavier weight.
  • Plastic connective components are susceptible to failure. These are located on the weight plates and handle joints.
  • High weight-cost ratio. At $4.68 per pound, these are expensive for the weight you get.
  • Requires proper alignment when re-inserting into the cradle. Otherwise they can become stuck. This can be tedious during workouts.
  • Shape plate edges are abrasive. They can damage floors and be uncomfortable on exercises like the goblet squat.
  • Rattles when shaken. This is a sign of mediocre build quality and susceptible to failing.

Compared To The Other Heaviest Adjustable Dumbbells:

NÜOBELL Review: the Good & the Bad

I’ve not personally used these but overall, the reviews are positive.

If you want a sleek and well-designed dumbbell and don’t mind paying the premium for the fast weight change mechanism, the Nuobells are awesome.

In fact, the rapid weight change mechanism is their main selling point (not the weight capacity).

Adjustable DumbbellTime Required To Change From 10-90lbs
Nuobell<1 second (^)
Powerblock2 seconds (*)
Bowflex3 seconds (*)
Braingain3 seconds (^)
Net Fit Boss3 seconds (^)
Ativafit2 seconds (*)
Ironmaster9 seconds (^)
* Based on personal testing / ^ based on video reviews.

If on the other hand, you want the heaviest dumbbell at a reasonable price, then the Nuobells may not be suitable.

At this kind of price, you can get the Bowflex, Powerblocks, and even the budget dumbbells which provide you with 90 pounds per hand.

9) Ativafit Dialtech – 71.5lbs.

The ativafit adjustable dumbbell is a mid-range weight

What They Are:

The Ativafit Dialatech 71.5’s can be thought of as the poor man’s Bowflex.

But that’s more of a statement about the price of Bowflex than it is about the quality of Ativafit.

The design and concept are similar to the Bowflex.

weight adjust mechanism on the ativafit adjustable dumbbell

These dumbbells go from 11 pounds to 71.5 pounds. And the weight is adjusted using a single dial-selector mechanism.

Unlike the Bowflex, which requires you to adjust both dials, the Ativafit changes weight by turning just one dial.

This makes for faster weight changes.

Why They Are Great:

  • Mid-range company selling moderately priced heavy dumbbells. Not as premium as Bowflex or Powerblock, but still an established name.
  • Mainly iron and steel components. These come together to form a durable dumbbell.
  • Single dial-mechanism is fast. Leads to quicker workouts.
  • Smooth dial changes. The mechanism feels good quality.
  • Contoured rubber grip with knurling. Easy to grip and good for beginners who don’t like metal knurling.
  • Compact design. An inch smaller in all dimensions compared to the Bowflex 1090’s.

The Problems:

  • Long dumbbell length. Awkward to use for some exercises such as the bench press.
  • The paint on the weight plates are prone to scratches. This will become more prominent over time.
  • Plastic safety switch susceptible to cracks. This switch needs to be pressed to unlock the weight change dial. So if this becomes damaged, the mechanism becomes unusable.
  • Not the heaviest adjustable dumbbell available. Only goes up to 71.5 pounds.

Compared To The Other Heaviest Adjustable Dumbbells:

Ativafit Adjustable Dumbbells Review (HOME GYM DUMBBELLS)

Having tested these when they first came out, I can say that the dumbbells themselves are of great build quality for the price.

They feel sturdy (more so than the Bowflex’s but less so than the Powerblocks).

So if you want a heavy adjustable dumbbell that’s slightly cheaper than the premium brands, then these are for you.

But bear in mind they aren’t the heaviest adjustable dumbbells you can get, and only go up to 71.5lbs.

If they were to go up to 90lbs, they would be a great choice for most people.

In general, UK buyers should avoid these as they can currently only be imported and are pricey (go with the Bowflex, Powerblock, Braingain, or DN Fitness dumbbells instead).

In general, you get what you pay for.

Ultimately, these are all some of the heaviest adjustable dumbbells in the US and UK.

Conclusion

Today I’ve shared 9 of the heaviest adjustable dumbbells you can get in the US and UK.

The heaviest adjustables on the market go up to 90lbs.

And these can be found for between $500-900, depending on the brand.

In contrast, budget brands such as Braingain, Net Fit Boss, and DN Fitness are cheaper yet they can still reach 90lbs.
